F5/F6/F7/F8/F9 Medium Efficiency Bag Air Filter Multi Pocket Filter for Air Conditioner and Ventilation System HEPA Filter

Medium-efficiency bag filters are typically used as pre-filters for high-efficiency filters and as final filters in air conditioning systems to reduce the load on high-efficiency air filters and extend their lifespan. 

They have a filtration efficiency of 60%-65% and are suitable for use in industrial cleanrooms such as pharmaceutical, hospital, electronic food, and automotive spray booths. 

The bag filters have a large filtration area, high dust-holding capacity, low cost, stable performance, and high dust capture rate. 

Special non-woven fabric or glass fiber filter media with electrostatic fibers provide a high dust capture rate (96%), high dust holding capacity, and high airflow permeability, ensuring long service life. 

They can be designed with frameless or framed options. Common sizes include 287*592*550, 592*592*550, and 592*592*600, but custom dimensions are available upon request.
