Plate type washable filter

This type of filter is used for the first filtration of fresh air in air conditioning systems, mainly filtering suspended particles and various foreign objects (such as dust, pollen, mites, sand and dust, spray paint, fiber dust, willow catkins, etc.) abo

frame	Aluminum alloy/stainless steel/galvanized steel sheet
filter material	high-quality polyester synthetic fiber
Skeleton	galvanized wire/stainless steel wire
efficiency	G2/G3/G4/M5/M6 (EN779)
Applicable condition	≤80℃
Product application	●Pre filtration of air conditioning and ventilation systems to avoid dust pollution inside the system ●Centralized ventilation and air conditioning system and return air filtration in the clean room extend the service life of the high-efficiency filter in the later stage ●The ventilation system of ordinary industrial plants meets the general cleanliness requirements for air ● Coarse dust filtration system for general building air conditioning ● Pre filtration of large air compressors

Product features

● Sturdy all metal frame structure with detachable outer frame design

The structure is sturdy and stable, ensuring that the filter will not deform or be damaged even in poor working environments. The outer frame can adopt a detachable design, making it easy to replace the filter material to achieve the purpose of frame reuse.

The supporting skeleton has high strength, ensuring that the filter layer can be used for a long time and is not easily deformed

The balanced spacing and double reinforcement design ensure the equal height pleat shape of the filter screen, so that the filter can achieve a large dust holding capacity when the resistance is low. Folding shape, the filter material is fixed diagonally at the front and back of this frame, and the filter material is tightly adhered to the frame to prevent any air leakage. Its filtering area is 2-5 times that of a general plane.

● High dust holding capacity, long service life

The filter material is made of high-quality polyester synthetic fiber, which can be cleaned and reused multiple times, with a long service life. The fluffy and gradually dense fiber structure ensures a high dust collection rate and a large dust holding capacity, effectively extending the service life of the back-end intermediate efficiency filter and reducing operating costs.
