Award Winning HEPA Vac

Continuing my series of EXAIR award winning products for 2014.  Plant Engineering’s readers voted the Heavy Duty HEPA Vac a silver award for Environmental Health. The HD HEPA Vac differs greatly from most of the EXAIR products.  We often improve a work environment by reducing noise level from compressed air blow offs or limiting the energy usage of a facility by conserving compressed air, but when EXAIR introduced the Heavy Duty HEPA Vac, we entered a new area of environmental health.


High Efficiency Particulate Air standards are set by the US Department of Energy. Originally, the standards were created to protect workers, the public and the environment from particulate that may be found in DOE’s nuclear facilities. (For more information on HEPA filtration consult DOE-STD-3020-2005.) The Heavy Duty HEPA Vac filter meets the HEPA standards to filter a minimum 99.97% at 0.3 micron level.  Each filter is tested in strict accordance with IEST-RP-CC-007. After testing the filtration, vacuum and ventilation companies discovered the added benefit of using HEPA filtration is to remove particulate that may inflame allergies or asthmatic symptoms. Pollen, pet dander, and dust are physically too large to pass through the HEPA filter. For instance, most pet dander is 5 microns and will become trapped inside the circuitous air passage route inside the HEPA filter. Also, HEPA filters will even filter airborne pathogens.  Engineering Toolbox list several nominal particle sizes to give you the idea of scope. By meeting these strict standards, EXAIR’s Heavy Duty HEPA Vac can be used in a whole new industry where HEPA filtration is required.

But wait there’s more!

We haven’t even talked about the HEAVY DUTY DRY VAC component of the Heavy Duty HEPA Vac.  The Heavy Duty HEPA Vac features the same hardened alloy construction of the Heavy Duty Dry Vac.  This alloy holds up to abrasive materials such as garnet, crushed glass, sand or hard materials like stainless steel chips, pipe plugs, or brass piping caps.  We tested the conveying power of the Heavy Duty Dry Vac, it moved 32 pounds per minute of steel shot blasting media, 146% percent more than a standard Chip Vac.  With all this vacuuming power, it still maintains a surprisingly quiet 82 dBA of sound level.

The Heavy Duty HEPA Vac would be the perfect item to clean out that clogged filtration system, or to clean up that spilled kitty litter that will clog up a standard electrical vacuum. It will not blow tiny particulate all over your shop and it can help protect your personnel from airborne particulate.

EXAIR Could Save You $15 While Eating Lunch

At EXAIR we manufacture engineered compressed air products.  We have compressed air saving nozzles, safety air guns, vortex tubes, and even pneumatic vacuums – all engineered to be as efficient as possible.

Considering that compressed air is the most expensive utility to generate, it makes sense to keep compressed air use to a minimum.  Replacing open pipes used to blow off or cool an application with an EXAIR engineered product can save time and add OSHA compliance to a workspace.

Mold Application 2

For example, the photos above show a dry mold application.  The end user initially used drilled holes in a series of pipes operated at 80 PSI to blow off and cool the molds during production.  Not only was this an inefficient use of compressed air, it was also unsafe.

With an average hole size of 1/8”, and an average of (60) drilled holes per mold, the potential savings were HUGE!  An open 1/8” hole at 80 PSIG can consume 18.4 SCFM.  Replacing this drilled hole with an EXAIR model 1103 1/8” Mini Super Air Nozzle will reduce the air consumption to 10 SCFM – a savings of 47%!  With the potential to upgrade 240 drilled holes to an EXAIR engineered nozzle, the total compressed air savings are over 2,000 SCFM.

With a savings of 2000 SCFM, and a lunch break of 30 minutes, this end user would save 60000 SCF – during lunch!  At a cost of $0.25/1000SCF, this equates to a savings of $15.00 every day during lunch alone.  Extrapolating the savings out on an 8 hour shift, the savings become:


$1,200/week  (operating (5) days/week)

$62,400/year  (operating (52) weeks/year)

In short, EXAIR nozzles put over $60k back into this company’s bottom line.
