The primary filter is suitable for primary filtration of air conditioning system. It is mainly used to filter dust particles above 5 meters. The primary filter is made of imported polyester fiber filter material. The internal and external melting points of the fibers are interlaced in space without direction. The structure is close, the fiber bond is firm, resistant to fracture, not easy to fall off. It has high light weight, high corrosion resistance, wear resistance and elastic recovery. It has low fluid resistance, high filtration rate, large dust capacity and long service life.
The primary filter filters out the dust, impurities, tiny particles and some strange gases (smoke, the air has some unpleasant smell) in the air conditioning unit, which is very beneficial to our daily life. Our life and work are closely related.
First of all, we must understand the effect of the primary filter on the application of the hepa filter. The primary filter is usually installed in the front of the air conditioning unit to filter some larger dust particles. It ACTS as a pre-filter for medium and high efficiency. The service life of the air filter is also extended due to more dust in the first contact. It is so fast that it usually has to be replaced every one to three months.
The main filter of air conditioning unit is divided into two parts: outer frame and filter material. First of all, let us introduce the preliminary effect of the frame, it is divided into: aluminum frame, paper frame, galvanized frame.
Filter medium: the effect of the filter medium on the primary screen is very important because it determines the level of the filter. Primary filter cotton is also known as nonwoven. It is a multi - component non - woven fabric with *** polyester fiber. It is heated and combined with the fiber to form an irregular staggered shape, resulting in a high dust removal effect, and has a strong adhesive force and will not break. In this way, *** will not cause re-pollution.
