5. High temperature resistant air filter, stainless steel frame, resistance to high temperature 250-300 ℃ filtration efficiency

This efficient filter, commonly used for primary filtration in an air conditioning and ventilation system, is also suitable for simple air conditioning and ventilation systems that require only one level of filtration.

G series of eight varieties, coarse efficiency air filter points are: G1, G2, and G3, G4, designed.the GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature resistant coarse filter).
