Camfil Farr leak tests each Megalam Panel and Ducted Ceiling Module HEPA/ULPA filter. Testing is performed in Class 100 (M3.5) clean zones within a Class 10,000 (M5.5) clean room. All testing is conducted by the controlled and documented procedures of Camfil Farr's ISO 9001-2000 certified quality system. To enhance upstream sampling capability, leak-scanning systems are equipped with dilution equipment for measuring high particle concentrations. Probe geometry has been optimized to maximize traverse rate and eliminate undetected leaks while maintaining isokinetic sampling. The entire face of the filter is scanned with overlapping strokes including the media to frame interface. As per customer requirements, Polystyrene Latex Spheres (PSL) and Emory 3004 are Camfil Farr's standard challenge aerosols.
Any leak with a penetration exceeding five (5) times the filter's average rated penetration is repaired with an alcohol-based silicone sealant according to industry standards or customer specifications. Polyurethane and other repair materials are available
