Product characteristics of initial effect paper frame filter:

This series of filters is mainly used for filtering particles with a diameter of 5 μ m. Made from domestically produced high-quality non-woven fabric, glass fiber, and decomposed fiber blended with special materials or exported polyester fiber as filter materials, with a wedge-shaped folding shape to increase the filtering area, and a high-strength cardboard frame, it is made into a plate structure. The balanced spacing and dual reinforcement design ensure the equal height pleat shape of the filter screen, so that the filter can reach a large dust holding capacity when the resistance is low. Folding shape, the filter material is fixed diagonally at the front and back of this frame, and the filter material is tightly adhered to the frame to prevent any air leakage. Its filtering area is 2-5 times that of individual solids.

2. The filter material adopts high-quality polyester decomposed fibers, with a long service life and a loose and gradually dense fiber structure, which ensures a high dust collection rate and a large dust holding capacity, effectively shortening the service life of the back-end intermediate efficiency filter and increasing operating costs.

3. There are different thicknesses to choose from, including 1 inch (21, 25mm), 2 inches (46mm), and 4 inches (96mm). 1 inch adopts a flat plate structure, while 2 inches and 4 inches both adopt a pleated structure.

4. Optional filtering levels: G2, G3, G4, F5 (EN779)

Primary paper frame filter screen Secondary use Application:

1. Primary paper frame filter used for clean return air debris

2. Partial high-efficiency filtration installation with pre filtration

3. Large civil buildings such as office buildings, conference rooms, hospitals, shopping malls, airports, etc. have scattered ventilation and air conditioning systems,

In ordinary industrial plants or clean rooms, there is a harmonious and centralized ventilation system with fragmented pre filtration

4. The initial effect paper frame filter is used for pre filtration of large air compressors

5. The initial effect paper frame filter air filter products are widely used in electronic technology, medical and health, biological products, food and beverage, mechanical and electrical engineering facilities, fine instruments, metallurgy and chemical industry, coating, air conditioning, printing, environmental protection industries, etc!
