PRE-FILTERThe FRONT FILTER IS THE latest development is MICron mesh filter, his mesh area is smaller than the general, in addition to adsorption of small dust particles, but also effective removal of hair. Surface purification after the treatment of fluxol, the dust attached to the surface of the fi

The air filter is the motorcycle's breathing system. If the air filter is blocked by dust, the intake resistance will become large, will make the engine output power decline, fuel consumption increases, the motorcycle sponge air filter how to clean and maintain?Motorcycle air filter with dry type

Motorcycle air filter is composed of box, partition, sponge filter, rice paper filter, box cover, intake pipe, is in the current use of air filter is insufficient on the basis of a primary filter sponge, this sponge can block more than 90% of the dust. Air filter for a long time don't clean up: t

When purchasing HEPA air filters, there are two elements to consider:the efficiency of the air filter and the resistance. An experienced air filter factory will estimate a resistance range based on air volume for your reference in order to make a preliminary selection of Hepa air filter ratings. S

Medium effect air filters can be used as intermediate filters for intake and exhaust devices, and are often used for return air filtration. It is usually divided into two forms: bag-type medium effect filter (windward surface is large, so the amount of empty dust is large) and plate medium effect

What kind of filter cotton is commonly used We usually divide them into three categories:What kinds of air filter material is divided into?First, synthetic fiber filter cotton:Synthetic fiber filter cotton is a new type of filter material, which has low resistance, light weight, large capacity, envi

(1) Use of primary air filter: filter section in general ventilation air treatment equipment or primary filtration of fresh air system. Features: The filter material can be replaced by itself, and the initial effect of the paper frame is one-time.Scope of application: suitable for primary filtration

As we all know air pollution is very serious, that is the main reason, more and more people choose HEPA filter.HEPA Filter full name is high efficiency particulate air filter.Effectively filter smoke, dust and pet dander and so on. Application area of high efficiency filter:At present, it is widely

Usually there are 3 types of air filter in air purifier. They are HEPA filter, activated carbon filter and prefilter. Different filters have different functions. Prefilter is in the first layer which can filter some large particle of dust. HEPA filter can filter out the 0.3 micron dust. And activate
