INSITU TESTING OF HEPA FILTER INSTALLATIONS

 

  INSITU TESTING OF HEPA FILTER INSTALLATIONS  


High Efficiency Particulate Air (HEPA) filters after manufacture are shop tested to remove >99.97% of the particles with a mean diameter of 0.3 microns from an air stream at rated flow and are evaluated in pre-approved test facility. After installation, these filters must be again evaluated in-situ at the point of use. This testing is used to detect leaks in HEPA filter installations in their operational condition, which is intended to test the seals, housing, terminal duct work and filter integrity. It ensures that all air entering the installation passes through HEPA filtration system.
