Plank Pre-filter, mainly filtering dust particles ≥5μm.

 Product Usage 
Mainly used in commercial and industrial ventilation systems, air conditioning systems pre-filtration.


· the filter material is made of high-quality polyester synthetic fiber with long service life, fluffy and denser fiber structure, the large air volume and high dust capacity, effectively extending the service life of the middle effect filter at the back end;

· lightweight plate structure with low initial resistance and strong flame retardant;

· the filter mesh can be made of galvanized mesh, filter mesh, stainless steel mesh, and plastic-sprayed mesh to enhance the filter strength;

· aluminum frame, galvanized frame, and stainless steel frame are optional for the outer frame to further enhance the hardness of the filter, which can avoid deformation, fracture, and distortion in the normal working environment.
