Features:

The filter material of the paper frame filter is 100% synthetic fiber, with an average efficiency (colorimetric method) of 30% to 35%; The weight calculation rule is 90%, 93%;

Glue the metal mesh onto the air outlet to prevent vibration and maintain consistent folding;

The outer frame is made of sturdy, moisture-proof hard paper frame. It will not deform, crack, or twist in a normal operating environment;

The filtering part is made by folding the filter material, which increases the filtering area, reduces the resistance of the filter screen, and achieves a longer service life than a flat filter screen;

Usage:

Paper frame filter screen is used for central air conditioning fresh air units and ventilation systems;

Used for program controlled switches and dedicated constant temperature and humidity air conditioning units in computer rooms;

Specially suitable for spray painting systems, pre filtration air compressors in spray painting workshops, and pre filtration systems for gas turbines;

Pre filtration system for high-efficiency filters;

Widely applicable for pre filtration of centralized ventilation systems in office buildings, shopping malls, hospitals, airports, and general industrial plants or clean rooms.
