Hepa Filtration

HEPA Filtration

High-efficiency particulate air filtration

A few uncollected particles or gas molecules can have extremely serious consequences in sensitive healthcare environments. Just imagine what harm contaminated air could do to the manufacture of pharmaceuticals and to other sensitive processes.

Healthcare hospitals, surgeries and clinics have special requirements when it comes to air cleaning, so an important part of our business concept is to help you analyse and specify your requirements. We have a complete range of filter solutions to satisfy your every need.

HEPA/ULPA Testing
Leak tests

Camfil 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'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 Emery 3004 are Camfil's standard challenge aerosols. (see top banner, Left)

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
Smoke test

As in scanning test, leaks are located with the aid of heterogeneous, highly concentrated oil mist. The filter is placed horizontally and the oil mist is allowed to filter gently through the filter. With a dark background and suitable lighting leakage can be confirmed purely visualy. Wisps of smoke passing the filter through holes in the filter are clearly visible. (see top banner, right image)
