Fume Hoods


Laboratory fume hoods provide protection to laboratory personnel and laboratory environments by preventing contaminants such as chemical vapors, dusts, mists and fumes from escaping into the lab environment and potentially harming the lab personnel.

Our personnel are trained in testing all types, brands and sizes of fume hoods. Testing consists of a visual inspection of the hood including checking all controls and alarms, face velocities readings to insure proper airflow, and smoke trace testing to insure that the fume hood is working properly. In addition, we can repair and upgrade fume hoods including new monitors, sash sensors, zone presence sensors and other recommendations for optimum operation of the fume hood and energy cost savings when the fume hoods are in use or not in use.

HEPA Filter Banks


We have worked with HEPA filter systems for over 40 years. We can test and certify existing HEPA banks, furnish and install new ones, or upgrade from current ASHRAE efficiency filters.

We also specialize in providing replacement of prefilters and HEPA filters in bag-in/bag-out containment equipment. Our technicians are trained and certified for respirator use as well as in gowning procedures. We can take care of any type of filtration need your facility requires.
