Leak detection method of high efficiency filter

Basically, the leakage test of the high efficiency air filter is to apply challenge particles to the upstream of the high efficiency air filter, and then search for any leakage on the surface and frame of the high efficiency air filter with a particle detector. There are several different ways of leak testing, which are suitable for different occasions. The test methods are:

I、 Gas gel photometer test method;

2、 Particle counter test method;

3、 Full efficiency test method;

4、 External gas test method. (The content is for reference only. If you have problems or encounter problems, please consult online or call us. We will serve you wholeheartedly.)
