▲Firm frame could be detachable: by adopting firm panel aluminum frame, matched with aluminum angle, strong and steady structure. Thus, filters could be operated and not easy to be changed in shaped in bad condition. Detachable frame could be convenient for filter medium change and repeat use.
▲Light weight panel structure, quality PET synthetic fiber filter medium materials, which is low initial resistance good fireproofing character. Reinforcing rib of filter mesh enhances more sturdiness. Meanwhile, uniform space and double reinforcing rib design ensure equal height pleating shape of filter mesh. Thus, filters could reach max dust holding capacity at min initial resistance.
▲Filter medium materials is made by quality PET synthetic fiber and have durable service life, which could be washed many times. Fluffy and gradually thick structure ensure high dust holding capacity rate. Therefore, service life is e of medium efficiency filter after it is expended efficiently.
Applications of Pleated pre-filter with media holding frames:
HVAC ventilation systems of office buildings, meeting room, hospitals, commercial plaza, airport and other buildings. Also as pre-filters for factory workshops or central ventilation air conditioning of cleaning room.

Structure: Filter medium materials is PET filter fabric or synthetic fiber fabric. Filter efficiency: G2 G3 G4. Aluminum mesh or powder coated wire mesh as Protection mesh. Frame is galvanized steel plate, aluminum or stainless steel.
▲Low initial resistance, high dust holding capacity;
▲Economical and practical, good washability;
▲Temperature resistance 100℃ and humidity 100%
For coarse efficiency filtration, pre filter for HVAC system.
