Paper Frame Pleat Filter

1, Surface mesh adopt rust treatment process,with good appearance and duration.

2, Large media area

3, Save space

4, Adopted the synthetic fiber material, reasonable structure, large dust holding capacity and stable performance.

5, 100% factory inspection

6, Adopted the optimized “V” shaped filter bag structure, large air volume, low resistance and long service life.

7, It can be washed and reused . (this may cause the result that the product performance will be changed a little, the efficiency will be decreased, and the wind resistance will be increased. )

8, Not easily deformed and damaged, suitable for poor working conditions

Advantage：

Large filtration area: The filter area is about 5 times larger than that of the general flat filter by adopting the gradient folding structure, which can make full use of the filter surface and improve the filtration efficiency.

Large air volume and low resistance: It can allow a large air flow to pass through, and the resistance generated is small, which will not cause excessive pressure loss to the ventilation system and can ensure the normal operation of the ventilation system.

High dust holding capacity: The large filtration area and reasonable structural design enable it to accommodate more dust and particulate matter, extend the service life of the filter, and reduce the replacement frequency.

Compact structure: The volume is relatively small, occupies less space, and is easy to install and arrange in various ventilation systems, especially suitable for places with limited space.

Low price: Compared with other types of high-efficiency filters, the cost of primary folding filters is lower, with a higher cost-effectiveness, which can reduce the operating cost of the ventilation system while ensuring a certain filtration effect.

Environmental protection and energy saving: Some filters with paper frames can be incinerated after use, which is pollution-free and meets environmental protection requirements; and its low resistance can reduce the energy consumption of the ventilation system and achieve energy saving.

structure：

Structural composition: mainly composed of outer frame, filter material and protective net.

The outer frame is usually made of cardboard frame

The filter material is generally a synthetic fiber material such as non-woven fabric, chemical fiber cloth, etc., which is folded into the outer frame.

The protective net is mostly made of galvanized welded mesh, aluminum mesh or stainless steel mesh, which is attached to the air outlet surface of the filter material.

Working principle:

Filter dust particles in the air by interception, inertial collision and other methods. When air containing dust particles flows in, particles larger than the filter material sieve hole are intercepted: larger particles deviate from the airflow direction due to inertia, collide with the filter material and are filtered out. The folding design increases the windward area, making the airflow more stable and uniform when passing through the filter, which can effectively block dust particles between pleats, and clean air flows out evenly from the other side.

Product parameters：

Beside the above standard sizes, it can be customized any size and efficiency (G1, G2, G3, G4, F5, F6, F7,F8, F9) if you need.

Application field：

It is mainly used in the primary filtration section of clean rooms, mainly used to filter dust particles larger than 1μm. It is widely used in optical electronics, medical and pharmaceutical, food and beverage, biological laboratories, touch screens, precision instruments and other industries. It is generally used in conjunction with other air purification equipment, such as FFU, air shower room, clean room, etc.
