Thanks to its inherent quality and strong performance, the air filtration combination can be widely used in clean workshops, laboratories, dust-free workshops, electronics, machinery, communication equipment, etc. Air self-cleaning filters are available in five types: coarse, medium, high, sub-high, and ultra-high efficiency.
Coarse filters are mainly made of carbon steel, low-alloy steel, stainless steel, etc., and are marked as C, M, S. Generally, coarse filters are installed in the piping before the inlet of pumps and compressors or in front of flow meters.
Medium-efficiency filters belong to class F. The F-series medium-efficiency filters come in two types: with bags and without bags, including F5, F6, F7, F8, F9; the bagless types include FB, FB, FS, FV.
The main performance indicators of the air-source filter pressure reducing valve manufacturer include: filtration efficiency, rated flow, rated flow, initial resistance, dust-holding capacity, and dimensions. Tests were conducted according to the method described in JG/T22-1999 "Test Method for Performance of Air Filters for General Ventilation"; when the filter media particle size is greater than 1.0 micron, the removal rate is greater than 70%, and <99% is the effective type.
