 Description

Adopting non-woven cloth and glass fiber as filtering materials, primary-efficiency filter chooses pleated wedge shape to enlarge the actual effective filter area. It is designed as plank structure supported by metal mesh clip or inner joints frame together with metal outer frame. So it features low resistance, long endurance, washable, economical and practical.

Application

Primary-efficiency filter is fit to pre-filtering for central air-conditioning ventilation system, combustion gas turbine and air compressor.

Structure

Primary-efficiency air filter is designed for two kinds of structures-joint frame and general framework. The former is strong, even filtering material, but time-consuming in manufacturing whereas the latter is easy to change filtering material, time-saving but not as strong as the former.

Filtering material

Activated carbon filter adopts washable non-woven cloth, activated carbon, synthetic fiber, chemical fiber (imported), glass fiber (imported), Kam-convex mesh (nylon net). Non-woven cloth and glass fiber are more widely used with primary or medium efficiency.

 Related Common Sense

Adopting metal framework, primary-efficiency filter presents us feeling of Chinese characteristics. This choice is the same as that of disposable paper plate, but metal framework is strong, endure. Moreover, it reduces the cost because it only needs to change filtration core if its longevity comes to the end.

Confined to structure and cost, metal primary-efficiency filter adopts non-woven cloth as material. However, there is one point needing mentioning that some clients request the manufacture to use washable filtering material.

In principle, any material, after being washed (including rinse), will be greatly abated in filtering performance. That all parameters turn so bad will lead the filter to being abandoned as a total loss. Though some materials can be washed, they are at the expenses of reducing filtering efficiency. Therefore, we don’t support to sacrifice filtering performance to prolong the endurance. What we advocate is to change filtering core.
