Primary effect plate filter

Function of primary filter: it has a large wrinkle filtering area and can effectively filter large particles, dust, mosquitoes, hair, etc. Ensure the fresh air volume while the air enters the room from the outside.

Replacement period: three to four months, determined according to the air quality of the place of use.

1. The primary effect filter is mainly used to filter more than 5um of dust, which is used for pre filtration of air conditioning and ventilation system to avoid dust pollution inside the system; At the same time, the primary filter is used for pre filtration of large air compressor, centralized ventilation and air conditioning system in clean room and return air filtration, so as to prolong the service life of the later stage high-efficiency filter; In fact, the primary effect filter is also used in the ventilation system of ordinary industrial plants to meet the general clean demand for air.

2. The primary efficiency filter is divided into primary efficiency plate filter, primary efficiency folding filter, primary efficiency paper frame filter, primary efficiency nylon net filter and primary efficiency bag filter. As the pre filtration of air filter, they can effectively block dust particles in the air and protect the medium efficiency and high efficiency filters at the back end. The service life of high-quality primary efficiency filters under normal circumstances is 3-6 times. To avoid the impact of blockage on the air quality of the filter surface, we should still pay attention to the replacement cycle.

3. The primary efficiency filters are divided into: folding primary efficiency filter, flat primary efficiency filter, primary efficiency filter and bag primary efficiency filter that can be cleaned by the sub parent frame.

4. The filter materials of primary effect filter include polyester synthetic fiber, nylon net and activated carbon.

5. The outer frame of primary effect filter is made of aluminum frame, galvanized steel plate frame and paper frame.

6. The filtration efficiency level of primary filter is G1, G2, G3 and G4.
