The DD2400 will handle about 80% of all Concrete Grinding Dust Extraction Applications and that percentage is growing daily as more and more applications are being fulfilled by this very powerful, compact, versatile and east to handle and maneuver vacuum.

How Powerful is the DD2400?  You'll be impressed when only two (2) motors are used!  This can be especially important when only a 15 Amp Circuit is available.

Benefit of switching from 3 to using only 2-Motors.  After heavy grinding or after using the coarse grit diamonds, when you switch to the finer diamonds it is suggested that you only use 2-motors.  By using 2-motors you'll find that by reducing suction power (or lowering the CFM) the incoming dust and debris will fall naturally inside the collection tank before it can reach the vacuum's filters.  This procedure further helps at preventing the filters from premature blinding.

Applications:  Masonry and Concrete Grinding using Floor Grinders up to 25", Tuck Pointing (see Y-Hose Splitter, below), Manufacturing, Industry, Chimney Sweep Cleaning, Hardwood Floor Sanding, General Purpose Commercial, Residential & Industrial Use.

The DD2400 (3-motor) is very similar to our DD2000 (2-motor) Vacuum, including is collection capacity (150 lbs. of silica dust) and our AIRFlow HEPA Filter System.

The difference is the motors:

  • DD2400 uses high speed motors that create more CFM - used for airborne dust applications.

  • DD2000 uses 2-stage motors that create above average CFM but significantly greater H20 values (for lifting heavier objects.)

Extremely Durable, Portable and Compact.  The 24 Gallon Tank,  while providing large collection yields, is very mobile easy and compact.  Its handles, wheels and casters are all built into the tank to provide A+ protection from breakage and for transporting through residential door ways.

The strong, molded polyethylene tank provides incredible versatility and durability:  Highly recommended for abusive situations and applications, including its ability to withstand breakage such as when a fork lift rams into it or when falling out of the truck when going down the highway.

Productivity Vacuum for Tuck Pointers - With 3-motors you can add the Y-Splitter to operate two dustless hand grinders from the DD2400.  With this combination, both tuck pointers can grind brick mortar joints all day "without having to clean filters or empty the tank!"

Collection & Productivity Advantage:  Powerful 2 and 3-Motor suction plus its large tank (but still compact and portable) easily doubles operation or productivity times.

AIRFlow HEPA Filter System - Expect to extract large volumes of the finest of powders without suction drop or contamination of neither the inside of the tank or your work area.

Additionally, the Dust Director's unique HEPA rated cartridge filter permits simultaneous dry and wet recovery without the hassle of changing filters during a clean-up project.  The filter is easily removed from its filter cage for washing and re-use.

Easy Storage, Transportation & Handling - Equipped with durable metal tank-clamps that won't crack, snap or wear from heavy use ~ even when the tank is completely full and being handled with its collection capacity of 140 lbs. of silica (without incurring suction drop.)

AIRFLOW HEPA FILTER SYSTEM - Background, Filter Information

AIRFlow HEPA Filtration - the Ultimate Filter System?  The AIRFlow HEPA Filter System includes a HEPA Efficiency Pleated Cartridge Filter and your choice to use the Clean Extreme Filter Collection Bags or the Self-Cleaning Flutter Filter:


Dust Release & Water Shredding HEPA Cartridge Filter, included with each Dust Director Vacuum & Cyclone.DUST DIRECTOR's CLEAN EXTREME HEPA CARTRIDGE FILTER.  Product Made in the USA.

Utilizing state of the art manufacturing and in house testing, the filter has been specifically designed to provide the performance required for the proper operation of a Dust Director® Vacuum.

Wet & Dry Use + HEPA Rated + Longer Life with Applied PTFE Membrane:  The Non-stick Dust Release & Water Shredding PTFE Membrane enhances the filter's capabilities in several areas, including filtration efficiency (meets or exceeds a HEPA rating), cake release, cake prevention, "extreme" service life.

A filter's base fabric is typically made of woven or felted synthetic fibers, natural fibers or fiberglass.  The membrane is a mechanically applied surface treatment (extremely thin, from 0.4 to 10.0 mils) that requires the filter's fabric for support.

Benefits of the Expanded PTFE in Dust Collection Applications:

Increases Filtration Efficiency to help meet EPA-mandated limits on exhaust emissions while providing the following benefits:

1)  Provides surface filtration rather than depth filtration (which is provided by conventional filter fabric).  Surface filtration keeps the captured dust particles away from becoming impregnated into the base fabric, thus reducing fabric abrasion and extending the filter's service life.  With longer service life you won't need to change the filter nearly as often which reduces your replacement cost and downtime during operations.

2)  Reduce pressure drop, cut energy (motor) costs.  The membrane typically prevents pressure drop across the filter by about 10 percent.   This in turn cuts wear on the vacuum's motor(s) while reducing power consumption by as much as 33 percent!

3)  Extreme Dust Cake Release / Extreme Dust Cake Prevention.  The expanded PTFE membrane is slicker than a conventional filter fabric and it easily releases any dust cake during cleaning.

4)  Most people purchase a vacuum cleaner based on improvements or features of the vacuum cleaner.  The vacuum's cartridge filter alone, applied with a PTFE membrane, will increase the vacuum's performance by as much as 25 percent - thereby increasing production rates for your entire operational process.

5)  Extreme & Diverse Applications.  The expanded PTFE membrane can withstand the most abusive of applications, dry or wet, and temperatures up to 600°F --- highly suitable for high-temperature applications such as when removing hot mastics.  Additionally, as stated, the filter is complete washable.

6)  While the PTFE membrane increases the filter's and vacuum's cost, the initial cost is offset by improved filtration efficiency, vacuum performance and longer filter life.


Clean/Extreme Filter Collection Bag.  HD, cloth filter bag installs into any W/D vacuum, maintains suction performance, collect dry, wet, sharp debris.CLEAN EXTREME FILTER COLLECTION BAGS (3 included per vacuum):

With a Clean Extreme Filter Bag installed you can expect to collect large volumes of silica dust - to the tank's inlet port - without incurring suction drop or without the filter bag tearing or accidentally bursting inside the tank.

Improve Productivity.  How many times are you stopping to clean or maintain the vacuum's filter or having to empty the tank all too often?  With a Clean Extreme Filter Bag installed, suction power stops when dust begins to exit through the tank's 2" inlet port --- fine powders collected and contained within the Clean Extreme Filter Bag will not cause blinding (i.e. the powder will not cake the bag's lining, suction is not diminished.)

When vacuuming any type of power, for hours at a time and you happen to notice suction drop . . . With a Dust Director Vacuum you simply turn off the vacuum, doing so will cause the Clean Extreme Filter Bag to deflate;  when you turn the vacuum on the bag inflates and suction resumes 100% ~ Guaranteed.

Are you grinding dry and you come across wet concrete, stone or mortar?  No problem - Clean Extreme Filter Bags work even better when the surface is damp!

Besides maintaining suction and collecting large volumes of powder without suction drop, Clean Extreme Filter Bags also collect:  Moist debris, sharp objects and hot mastics ALL AT THE SAME TIME.  Additionally, when you remove the filter bag you'll notice that the inside that the inside of the tank, the outside of the bag and the HEPA cartridge filter are "clean":

Clean Extreme Filter Bags:  Collects anything - powders to sludge - they fill to capacity, powders do not blind suction, no accidental bursting or tearing inside the tank or while being handled during disposal, and everything stays clean ~ Guaranteed.

Extreme Filter Bags install into wet/dry vacuums with an inlet port - Tanks stay clean, cartridge filters stay clean - even after collecting 140 lbs. of dry concrete dust.

HEPA Cartridge Filter Stays Clean

Clean/Extreme Filter Bag:  Large collection yields, everything stays clean including cartridge filter, tank & the outside of the bag.

FLUTTER FILTER - Optional Filter.

Flutter Filter Basket - Constantly shakes, beats & flutters, prevents filter blinding without electronic pulsing.The Flutter Filter is a self-cleaning drop-in filter that may be used instead of the Clean Extreme Filter Collection Bag.  As soon as the vacuum is turned on the tightly weaved "but loose fitting" Flutter Filter beings to flutter and shake, using the air speed and turbulence inside the collection tank to create its motion.

Constantly and naturally in motion, dry debris and roughly 50% of the powders are kept from blinding the surface of the Flutter Filter and causing suction drop.  

Like a Clean Extreme Filter Collection Bag, any accumulation or blinding on the surface of the Flutter Filter is naturally released when the vacuum is turned off and on:  When the vacuum is on the Flutter Filter raises, when the vacuum is turned on the filter drops . . . effectively releasing any caking.

DD1000 Watt - Shown with Flutter Filter installed.Additionally, to help prevent blinding while the vacuum is on, a floating filter cage inside the Flutter Filter swings freely and loosely as it shakes and knocks itself about using the air speed and turbulence inside the collection tank

When you're on a job site it's nice to have options . . . with a Dust Director® Industrial Vacuum Cleaner you're able to use either the Clean Extreme Filter Bags or the Flutter Filter.

Clean/Extreme Filter Collection Bag.  HD, cloth filter bag installs into any W/D vacuum, maintains suction performance, collect dry, wet, sharp debris.The Clean Extreme Filter Bags are the absolute best filter system on the market for collecting "large volumes" of silica dust while maintaining maximum suction performance and for keeping everything clean inside the tank and even during removing and handling ~ everything is kept clean and there isn't a mess.

But the Flutter Filter works impressively as well, reduces or eliminates the cost of replacement filter bags, uses no electronics to shake or pulse itself clean and it is completely re-useable and washable.

Flutter Filter - Specifications, Additional Features:

  • High Efficiency Filter Media, 96.5 @ 0.3 microns

  • Dry powders do not impregnate the material like commonly used "felt" filters

  • Keeps the vacuum's HEPA Cartridge Filter from caking.  While it may become dusty it will not cake.

  • Durable - Completely Washable

  • Versatile - Collects dry or wet debris without compromising its effectiveness.

OSHA's Silica Dust RuleOSHA's Final Rule to Protect Workers from Exposure to Respirable Crystalline Silica

Rule requires engineering controls (tools and equipment) to keep workers from breathing silica dust.

What is Respirable Silica Dust?  These tiny particles (known as "respirable" particles) can penetrate deep into workers' lungs and cause silicosis, an incurable and sometimes fatal lung disease.  Crystalline silica exposure puts workers at risk for developing lung cancer and other possible debilitating respiratory diseases such as chronic obstructive pulmonary and kidney disease.

How Much Respirable Silica Dust is Safe to Breath?  OSHA has issued their Final Rule to curb these respirable and kidney diseases in America's work force by limiting a worker's exposure to respirable crystalline silica to 50 micrograms per cubic over an 8-hour shift.

Packet of sugar - example of 53 micrograms.What Does 50 Micrograms of Respirable Silica Dust Look Like?  A good example may be one of those small paper packets of sugar or artificial sweeteners found in restaurants.

When used to demonstrate the dust concentration inside a building, the size of a football field (100 yards x 53 yards x 14' high).  The weight of one of those little packets is 53 micrograms, which is slightly over the PEL (permissible exposure limit) for Silica Dust of 50 micrograms.

Such a fine dispersing of dust at this concentration would essentially be invisibility.  It is also enough to put the workers at risk by contaminating the work area --- the size of a football field x 14' high.         


OSHA_Photo_1.jpg (848150 bytes)OSHA's Respirable Silica Dust Law - Effective:  23 June 2016.  Since 1999, the Dust Director® has been involved with various organizations aimed at improving the health and safety on construction sites.  On a meeting, dated 23 April 2014, the Dust Director® was invited to participate in a discussion about OSHA's upcoming Silia Dust Standard.  Besides the representatives from OSHA, the following organizations were also present:


  • CPWR (Center for Construction Research and Training)

  • Various university research scientists and professors

  • Health and environmentalist

  • Mike Kassman, National Safety Coordinator for the International Masonry Institute (IMI)

  • Jerry Scarano, Vice President of the International Union of Bricklayers and Allied Craft Workers (BAC).

In past meetings, by the use of various air testing meters, NIOSH determined that the Permissible Exposure Limit (PEL) of a worker being exposed to silica dust should not be greater than 93.4.  [On record, NIOSH tested the Dust Director® System (dust control guard and vacuum), and determined the complete system "provided the greatest reduction of capturing silica dust at 94% than any other vacuum and dust guard that was tested.]

Currently, to simplify the understanding and importance of containing silica dust exposure, OSHA and all parties involved, have adopted the buzz phase of "visible dust," as their measurement of whether silica exposure is being sufficiently contained for both the workers and public.


OSHA_Photo_6.jpg (988907 bytes)CASE STUDY:  Dust Left to Fly from a Skyscraper ~ An interesting case study was provided by a Detroit contractor who was tuck pointing at a high rise office building in downtown Detroit, 35 floors above the sidewalks.  A summarization of his findings on silica dust exposure is as follows:

  • Two workers were tuck pointing an office building, 35 floors up, without the use of dust control

  • The thinking was, to leave the silica fly and let it disburse into the sky . . . that it wouldn't harm anyone or anything

  • As the safety coordinator for the company, he monitored the air quality of his workers

  • His air quality readings were as follows:
    >  Employee "A" was working in air quality that measured 85 times over the NIOSH established PEL
    >  Employee "B", working downstream from employee "A", was receiving a concentrated dose of dust as his air quality measured 135 times over the PEL!

While this case study shows how "visible dust" may be seen, more importantly was the moral obligation we need to take for our construction workers, the public, and the environment.


Dust Emissions --- Does Your Vacuum Leak Dust?

Dust linkage, from a standard type wet/dry vacuum. Dust linkage (rear view) from a standard type wet/dry vacuum.

Check your vacuum!  With OSHA'S "No Visible Dust Law", is there a gasket beneath the motor head to seal the tank?

With the OSHA ruling You will get fined using a vacuum that leaks.

  • With a Dust Director® Vacuum, Like-New Suction is Every Time -
    Unlike other vacuum cleaners where the same cartridge filter is used again and again and again . . .

  • With a Dust Directo® Vacuum, the HEPA cartridge filter stays clean.
    While it may get dusted, it will never become caked
    ~ Guaranteed.


Poured in place urethane gasket, beneath the head of a Dust Director Vacuum.Urethane Motor Head Gasket.  Beneath the motor head of every Dust Director® Vacuum & Cyclone is a poured-in-place urethane gasket that is used to ensure a positive airtight seal between the motor head and its tank.  Commonly used shop vacuums and even higher priced vacuums will use foam or nothing at all.

The urethane gasket ensures against dust leakage into your work area and prevents even the slightest loss of vacuum which would naturally reduce suction power.  Many wonder how the suction of a Dust Director® Vacuum and Cyclone seems so much more powerful than other brands, one of the reasons is the urethane gasket.

Dust Director's Increase in Suction Power?  While a complete Dust Director System (vacuum and dust guard) have been successfully monitored by NIOSH to operate within the guidelines of their established PEL, a very important  feature in all of the Dust Director® Vacuums and Cyclones is the poured-in place urethane gasket.

While some vacuums use foam as a gasket, 90% of all vacuums use nothing!  This startling statistic includes vacuum's that cost well over $2000 dollars.  While the Rigid vacuum, for example, does not use any type of gasket (while leaking profusely), the consensus among morally conscience contractors is a Rigid vacuum is simply not designed to be used for silica dust containment.



Dust Director® vs. the Competition:


Bosch Vacuum.


Fein Vacuum.


Hilti Vacuum.


Ridgid Vacuum.


On a visit to masonry tuck pointers in Chicago and Detroit, the suction power of the Dust Director® Vacuums was compared to the Bosch 3931 Airsweep, Hilti VC20 and Fein Turbo I vacuums.  Simply by placing our hand over the inlet port of  each vacuum, the following was the agreed upon results:

  • Dust Director® Model DD1000:  15% greater suction vs. Bosch & Fein, 25% greater suction vs. Hilti

  • Dust Director® Model DD1200:  Easily 20% greater suction than the DD1000

  • Both Dust Director® models where considerably lighter than Bosch, Fein and the Hilti vacuums.




Optional Equipment:

PS-300 Power Station, for use with any 1, 2 or 3-Motor Dust Director VacuumsOn large concrete grinding projects, for cost considerations, improved productivity and ease of disposal and handling of the extracted dust, you may want to consider a Power Station or a Separator:

Power Station:  A Power Station is simply an open cylinder placed between the vacuum's collection tank & motor head.  Installed, 1/3 of the motor head and the complete HEPA cartridge filter are removed from the collection tank.  Now, with 33% more room in the collection tank, collection yields increase 33% for longer operating or productivity times.

Additionally, by collecting an additional 33% more dust in the same Clean Extreme Filter Collection Bag, bag consumption cost drops 33%!  Plus . . . with the HEPA cartridge filter completely removed from the collection tank, as the filter bag fills it will not encased or suffocate the cartridge filter . . . which further helps at maintaining a high level of suction.

PS-55, Separator for a 55 Gallon Drum.Maxi-Bag Separator.Separator:   A Separator is simply placed in front of any size vacuum whenever you want more collection yields and/or productivity.  Additionally, if you are finding the filters in your vacuum are blinding or clogging too soon, you probably need to use a pre-separator.

Another way of looking at how a Separator works is as follows:

  • With the filter system of a Dust Director Vacuum maintaining incredible airflow, the vacuum is looked upon as the "power house" and the Separator as the vacuum's collection tank.

  • In this arrangement, besides keeping the vacuum's filters clean, Separators provide for easier remove, handling and disposal of the debris for increased productivity on the floor.

For any concrete or terrazzo floor grinding project, a Separator is essential as it:  Easily quadruples collection yields vs. filling the vacuum's collection tank, keeps the vacuum's filter cleaner and operating at 100% power, provides for easy handling and disposal of debris.

For additional information, pricing and ordering of a Power Station or Pre-Separator, see  Vacuum Accessories



30" Floor Sweep attached to the DD2400 to vacuum dry concrete dust or wet slurry.30" Squeegee / Dry Powder Floor Sweep.  A fast growing application for the DD2400 is the attachment of the 30" Floor Sweep for vacuuming dry powders, dirt and sand.

Extremely Fast and Effective - "Sweep as fast as you can walk." 

Simple to attachment to the 24 gallon poly tank.  With the vacuum's 3-motor suction power, floors are impressively swept and vacuumed for that "white glove" test - ready immediately for that next grit or before applying your sealer or coating.  As an added bonus, install the Wet Conversion Filter, and the DD2400 can now squeegee liquids, slurry and chemicals.

Either way, wet or dry use, incredible productivity is obtained with the 30" Floor Sweep.  And when you consider the mess and abuse that concrete slurry does to expensive automatic floor scrubbers, the DD2400 and a 30" Floor Sweep is considerably less expensive and easier to maintain.



2" Aluminium Y-Port, fits all Dust Director Vacuums.Y-Hose Splitter.  For using two (2) hand held dustless angle grinders with the DD2400.  Price includes the Y-Splitter, (5) Hose Cuffs (for 1-1/2" & 2" dust ports on the dust guards) and a second 2" x 12' hose.  

Dust Director 3-Motor Vacuum - operates two (2) dustless angle grinders.In the Dust Director's working relationship with OSHA, NIOSH and the Center to Protect Workers Right (CPWR), various studies have shown that 80 lbs. of silica dust is created in an 8 hour day when tuck pointing (the grinding mortar joints 1/4" wide x 1/2" deep).

For productivity considerations, your only limitation in using a Dust Director 1-Motor Vacuum will be the size of the collection tank.  With a 10 or 12 gallon tank you'll be stopping at least twice a day to empty them.

With a DD2400 Vacuum - its filter system, 3-Motors, Y-Splitter & 24 gallon tank, two (2) can grind all day without having to tank to empty the tank!



Extension Cover unsnaps to cut a wall's inside corner.TUCK POINTING.  Add multiple lengths of 2" x 25' hoses (up to 75') and keep the vacuum on the ground and grind brick mortar joints.  Or, use the above Y-Splitter to operate two dustless tuck pointing angle grinders from the same vacuum.  In this arrangement, you can tuck point all day without having to clean the filters or empty the tank!
