Filtration and Environmental Testing

Filter testing ranges from flat sheet media to full size systems, in both air and liquid applications, in accordance with industry, military and commercial standards and specifications. In addition to qualification and third party comparative testing, laboratory and field test programs are implemented to support component and systems research and development, and to aid in developing strategies for solving specific filtration problems.

Airflow rates to 3,500 cfm; hydraulic, fuel and lube oil filter flow rates from 0.5 to 60 gpm at temperatures up to 250°F; and high pressure liquid flow rates to 10 gpm at 2000 psig, 8 gpm at 3,000 psig.
