Lab Equipment Testing

NSF-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 over 20 years each experience in this field, and an additional five with over ten years of lab equipment certification experience.

Our customers for this type of certification work 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. The mannequin in the picture mimics a lab technician. The test procedure measures the amount of sulfur hexaflouride gas ( which is injected inside the fume hood) that has escaped 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 CETA (Controlled Environments Testing Association) ASHRAE 110-2016 fume hood certification curriculum.

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 has to 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.
