About Us ACGIH Guidelines

Air Dynamics Follows the Standards of ACGIH

The American Conference of Governmental Industrial Hygienists, (ACGIH), provides guidelines on occupational health, including ventilation and exposure limits for airborne contaminants.  Where applicable, Air Dynamics designs its equipment and systems in accordance with the ACGIH Industrial Ventilation: A Manual of Recommended Practice, which sets forth best practices for controlling airborne contaminants to ensure safe, healthy environments for workers by effectively managing airflow, temperature, and contaminant control.

Key product types that support ACGIH‑compliant ventilation and air‑quality control include:

Local Exhaust Ventilation (LEV) Systems
  • Capture hoods, enclosures, and systems like the ActiveWallTM,  located at the source of dust, fume, or vapor generation
  • Custom ductwork and airflow controls sized per ACGIH capture‑velocity guidelines

 

Dust Collection Systems

 

Fume & Vapor Scrubbers
  • Activated‑carbon beds for solvent and VOC adsorption
  • Packed‑bed or venturi scrubbers for water‑soluble gases and mists
  • Regenerative and catalytic oxidizers when destruction is required

 

Mist & Oil‑Mist Eliminators

 

Portable & Central Vacuum Systems
  • HEPA‑filtered portable vacuums for spot cleanup of hazardous powders
  • Central vacuum networks delivering high‑flow, low‑pressure suction to multiple pick‑up points

 

General (Dilution) Ventilation Units
  • Make‑up air handlers and roof‑top units providing controlled fresh‑air flow rates per ACGIH air‑change recommendations

 

Environmental Test Chambers with Ventilation Controls
  • Chambers that maintain safe, ventilated operator zones for R&D or QA while meeting ACGIH exhaust criteria

 

Each of these products must be engineered—hood geometries, duct velocities, fan selection, filtration stages—to match the ACGIH’s specified capture velocities, face velocities, and airflow rates. When sized and installed correctly, they ensure workplace exposures remain below ACGIH Threshold Limit Values (TLVs) and support both worker safety and regulatory compliance.

 

Testimonials

"We love the vacuum and use it just about every day in our normal everyday routine. It has been a major help with maintaining clean floors and machines. We have also used it to unplug clogged pneumatic conveying lines where compressed air did not effectively work. In the past, we used brooms and compressed air to clean which caused the dust to float in the air, moving from surface to surface. The PLECO vacuum eliminates floating dust and its suction is powerful enough to get the fine dust out of the cracks and off the floor quickly. I like that it’s portable to move it where you need it."

Testimonials

"Daniel Lehman was so much more knowledgeable than the competition- probably more knowledgeable than anyone in the country, about industrial vacuums."

- C. Milum, Textile Company
Testimonials We recommend Air Dynamics!

"Working with Air Dynamics was an incredibly enjoyable experience for our engineering firm. They brought expertise to the table that we did not necessarily have in-house, and they conveyed it in a way that was easy for us, our shareholders, and our executives to understand. We would recommend Air Dynamics for anyone looking for a pneumatic or material handling conveying solutions."

- L. Samuelson, Engineer, power company
Testimonials

"The Desert Wind is the best technology we have found for testing and calibration laboratories. We use it within the aerospace and military sectors to assist the creation of parts development and provide part of the certification needed."

- Stephane Carpentier, Dir. Innovation & Development, CTA
Testimonials

"We purchased the PLĒCO 8.5 HP vacuum for our powdered colors business. We chose this substantially built vacuum over a European import that didn’t offer what this American made system did. We purchased a second unit because the first system performed excellent even after filling the canister again and again without affecting the pressure drop across the filters at all.

- G. Maynard, A Powdered Color Products Firm
Testimonials

"Technical support to design and evaluation of dust control / vacuum systems was stellar. Proposal and services associated with selected option are amazing. Product and service exceeds expectations."

- J. Paradis, Director of EH&S, USA Recycle
Testimonials

"The Air Dynamics’ dust collector is an excellent vacuum and has never cost us any downtime – it works great. Of all the vacuums I have ever used in the industry, it is the most robust - zero maintenance issues running 20+ hours a week with multiple users."

- R. Mason, Plant Manager, a plastics manufacturing company
Testimonials

"We’ve connected the vacuum hoses to our grinders and tried them out for the first time in last night’s shop class. The draw across all 5 dust collector machines is amazing! We are very pleased and praise your team for a job well done!"

- C. Zimmerman, Manufacturer’s Association
Testimonials Although they laughed, that didn’t faze us – we did our research and we had confidence in Air Dynamics’ application engineer we worked with.

"We’re a resource recovery company. We selected two PLĒCO 30 HP portable vacuum systems configured for bulk pickup. Our customer just laughed at us when the Air Dynamics PLĒCO vacuums showed up. They actually said, ‘they‘d never work!’ Although they laughed, that didn’t faze us – we did our research and we had confidence in Air Dynamics’ application engineer we worked with. The plant had a $100,000 central vacuum system; they even tried a “super sucker” with no decent results. The company gave up trying to recover the powdered tungsten themselves. We had their plant cleaned up in record time, even though the powdered tungsten weighed 1,150 pounds per cubic foot!"
