What are the characteristics of the primary air filter?

Time: 2022-07-27

Primary air filter is mainly used in the primary filtration of clean room for filtering dust particles above 1μm, which is widely used in optical electronics, medical and pharmaceutical, food and beverage, biological laboratory, touch screen, precision instruments and other industries, generally used with other air purification equipment, such as ffu, air shower room, clean room, etc. The outer frame material of primary air filter can choose stainless steel, paper frame, aluminum frame, galvanized frame and so on. The filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal hole mesh, etc. The protective mesh includes double-sided sprayed wire mesh and double-sided galvanized wire mesh, etc.

The primary air filter is the primary filtration of air conditioning system, and there are three styles of panel, folding and bag.

The primary air filters are G1 primary air filter, G2 primary air filter, G3 primary air filter and G4 primary air filter.

Primary air filter features.

Low price, light weight, good generality, compact structure.

Mainly used for.

1, central air conditioning and centralized ventilation system pre-filtration.

2, large air compressor pre-filtration.

3, clean return air system.

4、Pre-filtration of local high-efficiency filtration device.

5, high temperature resistant air filter, with stainless steel outer frame, high temperature resistant 250-300 ℃ filtration efficiency.

Composition of G series coarse air filter

The outer frame of disposable paper frame filter is generally divided into general hard paper frame and high-strength die-cut hard cardboard, and the filter element is pleated fiber filter material lined with single-sided metal wire mesh, with beautiful appearance and durable structure. The outer frame is made of strong waterproof board, which is used to fix the filter material that has been folded. The diagonal design of the outer frame can increase the filtration area and make the inner filter material adhere closely to the outer frame. The outer frame is bonded with a special professional adhesive around the perimeter to prevent air leakage or breakage caused by wind resistance pressure.

The filter material is folded into a high-strength die-cut cardboard, which increases the windward area. The dust particles flowing into the air are effectively blocked by the filter material between the pleats. Clean air flows out evenly from the other side, so the airflow through the filter is gentle and uniform. Depending on the filter material, the particle size it blocks varies from 0.5μm to 5μm, and the filtration efficiency also varies.
