Material and efficiency of primary effect panel filter
Material and efficiency of primary effect panel filterPrimary effect panel filter grade according to European standards to be divided into four categories, G1-G4, for the removal of particles above 5 microns, the efficiency of 40%-90%: G4 particle size efficiency ≥: 5.0um, the filtration efficiency is about 90%. Primary effect panel filter using non-woven fabric, fluffy glass fiber felt, plastic mesh or wire mesh, often non-woven fabric, glass fibre, etc. for the filter material, after pleating and fixing, the production of air ducts to increase the filtration area, the border from the economic point of view of the commonly used paper frames, due to the primary effect of the filter is often used in the central air-conditioning and centralised ventilation system pre-filtration, clean air return system, pre-filtering of large-scale air compressors, pre-filtering of local high-efficiency filtration devices. Considering the large air volume and its stability, it can also be clamped with metal wire mesh or supported by a keel frame and equipped with a metal frame to make special filter equipment with a plate structure. |
