Primary Efficiency Air Filter


●Product Features:
◎High dust-holding capacity
◎Low resistance
◎Panel Filters use light panel structure and good polyester synthetic fibers. Low initial resistance and good fire resistance.

◎Efficiency:G3、G4(EN779)

●Structure:
◎Use panel structure frames (paper, galvanized, aluminium, stainless steel) and ABS plasticor aluminum alloy coners,  to assure steable structure.

◎Use net-cover polyester fiber as material which makes our products have lower resistance and higher dust-holding capacity.

●Applications:
◎Pre-filtration of general air conditioner and ventilation system, to avoid inner pollution of dust collecting.
◎Pre-filtration of large air compressor.
◎Filtration of central ventilation& recirculation air conditioner system in clean rooms. Extend service life of next step high-efficiency filters.

◎Pre-filtration of ventilation system in general plants, reach standards for normal clean air requirements.
