Filter test system for general air filters according to ISO 16890. EN 779. ASHRAE 52.2
The Filter Test System has been developed especially for air filter testing according to standards ISO 16890. EN 779 and ASHRAE 52.2. We can fall back to a long-standing expertise in the field of construction and installing of filter test systems.
In the filter test stand the filter samples can be easily installed into the rotatable and movable duct sections. A filtrated air flow is loaded with particles. In this way information about the efficiency of the filters will be obtained. With these results the filter samples can be rated and classified.
