ALF 114 Test System
ALF 114 filter test system for general air filters according to ISO 16890, EN 779, ASHRAE 52.2
The ALF 114 Filter Test System has been developed especially for air filter testing according to standards ISO 16890, EN 779 and ASHRAE 52.2. Topas can fall back to a long-standing expertise in the field of construction and installing of filter test systems. Since 1995 we have been developing, manufacturing, and installing particle filtration test rigs compliant to standards and user-defined specifications. Test parameters include differential pressure drop, gravimetric efficiency, fractional efficiency and dust holding capacity.
In the ALF 114 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.
