The primary filter is suitable for the primary filtration of air-conditioning systems, mainly used to filter dust particles above 5μm. The primary filter has three styles: plate type, folding type and bag type. The outer frame materials include paper frame, aluminum frame, and galvanized iron frame. The filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc. The net has double-sided sprayed wire mesh and double-sided galvanized wire mesh.
Mainly used:
· Central air conditioning and central ventilation system pre-filtration
· Large air compressor pre-filtering
· clean return air system
· Pre-filtration of local high-efficiency filter device
Filters of this efficiency are commonly used in primary filtration of air conditioning and ventilation systems, and are also suitable for simple air conditioning and ventilation systems that only require primary filtration.
G series coarse air filter is divided into eight varieties, namely: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature resistant filter) coarse filter).
