5. Nylon mesh primary filter

Good washability, high air permeability, low resistance, high-temperature resistance, moisture resistance, acid resistance, and alkali resistance.
1) Application: Coarse dust filtration, typically used in fresh-air handling units, air outlets, and other areas where the system is exposed to outdoor air. It is also suitable for indoor air handling units and other air-conditioning systems that require high-volume filtration equipment, as well as environments with special requirements such as resistance to acids, alkalis, or high temperatures.
2) Outer frame: Aluminum alloy outer frame or nylon edging
3) Filter media: Nylon mesh woven from monofilaments made of materials such as PP, PA, and PE.
4) Inner frame: Galvanized iron wire or stainless steel wire
5) Efficiency: G1, G2 (EN779)
6) Weighting efficiency: < 65%
