Applications are in final filtration in clean rooms. These are rigid and compact high efficiency filters with large media area, which ensures low pressure drop even at high airflows. These are available in versions of Standard, Hi-flo and Super. The company has a state-of-the-art manufacturing set-up with pre, fine and HEPA media pleating machinery, aluminium foil corrugation machinery and a class 100000 cleanroom. HEPA filters are manufactured under class 100000 conditions and utmost care taken to achieve core tightness, strength against vibration and temperature resistance. They are also tested individually with thermal DOP to adhere to leak test with permissible leakage level of 0.01%. To ensure no compromise on quality, the company has a test rig based on CEN EN 779 fully equipped for testing pre and fine filters for dust spot efficiency and dust weight arrestance. The HEPA test rig is as per guidelines of IEST RP CC 001.3 to test the airflow, face velocity, scanning of filters against test aerosols for detecting leakages and fractional efficiency as per ASHRAE 52.2.
