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.

Compressed Air Calculations, Optimization, and Tips

EXAIR uses our blog platform to communicate everything from new product announcements to personal interests to safe and efficient use of compressed air. We have recently passed our 5 year anniversary of posting blogs (hard for us to believe) and I thought it appropriate to share a few of the entries which explain some more of the technical aspects of compressed air.

Here is a good blog explaining EXAIR’s 6 steps to optimization, a useful process for improving your compressed air efficiency:

One of the Above 6 steps is to provide secondary storage, a receiver tank, to eliminate pressure drops from high use intermittent applications. This blog entry addresses how to size a receiver tank properly:

Here are 5 things everyone should know about compressed air, including how to calculate the cost of compressed air:

These next few entries address a common issue we regularly assist customers with, compressed air plumbing:

In a recent blog post we discuss how to improve the efficiency of your point of use applications:

Thanks for supporting our blog over the past 5 years, we appreciate it. If you need any support with your sustainability or safety initiatives, or with your compressed air applications please contact us.  

Have a great day,

5 Things Everyone Should Know About Compressed Air

Most industrial facilities use compressed air as a common utility.  From running air tools to complex pneumatic controls, compressed air use is common.  What isn’t as common is a solid understanding of compressed air systems and their effects on a company’s bottom line.  Here are five basic things everyone should know about compressed air.

  1.  It isn’t free.  Many people, even those in the industry consider compressed air to be free or a low cost utility.  The fact is compressed air is a “secondary utility” in that it is generated as the result of consuming a primary energy source.

  2.  It can be your most expensive utility.  Because compressed air is created through a compressor driven by an independent energy source, generating compressed air can be costly.  The DOE conducted a study in 2004 which found that in a typical industrial facility approximately 10% of electrical consumption was consumed for the generation of compressed air.  The DOE also has a handy formula for calculating the cost of generating compressed air at your facility.

3.  The DOE has an incentive program for reducing energy used to create compressed air.  A new program launched nationally in 2012, the Superior Energy Performance (SEP) program provides industrial facilities with a roadmap for achieving continual improvement in efficiency while maintaining competitiveness.

4.  Safety concerns are real.  OSHA is in existence for a reason and their directives on compressed air driven devices aren’t to be taken lightly.  Fines hurt!!  Note – All EXAIR products comply with OSHA directives 1910.242(b) and 1910.95(a)

5.  Engineered compressed air products are the solution to the previous 4 concerns. We have put a great deal of time into the design and function of our products and it shows!  Installing an EXAIR engineered air nozzle has been proven to save over 50% of the compressed air when compared to common open pipe blow offs while maintaining or even improving the blow off force.

In the comparison above, the EXAIR model 1100 nozzle is consuming 53% less compressed air than the copper tube, while maintaining 13 oz. of force.  It pays to use engineered solutions!!

In short, we always like to say “Don’t waste your air!”  Our engineering staff is here for a reason – the design and implementation of intelligent compressed air products.  If you need assistance with your compressed air application, feel free to reach out.
