The National Sanitation Foundation (NSF) tests and certifies technicians for biosafety equipment testing. Precision Air Technology has 10 NSF-certified technicians. We have seven technicians with each over 20 years experience in this field, and an additional five with over ten years of lab equipment certification experience.

Our customers for biosafety equipment testing range from the largest medical research universities in the country with thousands of pieces of equipment, to small, start-up laboratories with only a few safety cabinets, fume hoods, or clean benches. We also test in-line HEPA housings in air handlers, animal racks, and table-top HEPA exhaust units.

The ASHRAE 110 fume hood test is a much more stringent test for fume hoods than a simple, airflow velocity test. In this image, the mannequin mimics a lab technician. We inject sulfur hexaflouride gas inside the fume hood. The test measures the amount of gas that escapes the hood and is in the breathing zone of the “technician.” Precision Air Technology has offered ASHRAE 110 testing for over 15 years, and has multiple technicians trained for this service.

Our ASHRAE 110 Fume Hood Testing manager is a Subject Matter Expert for the Controlled Environments Testing Association, 230 Washington Avenue, Suite 101, Albany, NY 12203 (CETA), ASHRAE 110, 2016 fume hood certification curriculum.

In this image, a Precision Air Technology technician installs a low flow, damper kit to retrofit an existing fume hood into a high-efficiency fume hood. Such installations reduce the amount of exhaust air taken in through the hood, lowering energy costs while continuing to protect lab personnel working in the fume hood.

Some containment laboratories have exhaust systems utilizing high-efficiency carbon filters to remove toxic gases in the airstream. The efficiency of these filter banks must be verified; we offer this type of testing as well. Much of the work we do in high-efficiency carbon certification is in government facilities. Precision Air Technology uses an infrared spectrometer to detect leakage, and Vertrel gas as a challenge agent.
