Hi,welcome to CLEAN-LINK!

How to choose the air filter of the central air conditioner?


In addition to constant comfort temperature, central air conditioning can also improve indoor air quality to a certain extent. The improvement of indoor air quality is mainly due to the important role of central air conditioning air filter, what is the air conditioning filter, how to choose the central air conditioning filter?

Air conditioning air filter definition

The air-conditioning air filter is mainly used for air conditioning in the engine room, pre-filtration of the ventilation system, air-conditioning clean room air-conditioning filtration, high-efficiency filtration pre-filtration, and air compressor pre-filtration. The outer frame is cardboard, the filter material is non-woven fiber felt, the folding filter material, and the back is supported by metal square hole net, which is economical.

Air conditioning air filter classification

The air-conditioning air filter can be mainly classified into three types according to the filter grade, namely, the primary air conditioner filter, the medium-efficiency air conditioner filter, and the high-efficiency air conditioner filter.

Primary air filter

The primary air filter is suitable for primary filtration of air conditioning systems and is mainly used to filter dust particles above 5μm. The primary filter has three styles: plate type, folding type and bag type. The outer frame material is paper frame, aluminum frame, galvanized iron frame, filter material is non-woven fabric, nylon mesh, activated carbon filter material, metal hole net, etc. The net has double-sided sprayed wire mesh and double-sided galvanized wire mesh.

The characteristics of the primary filter: low cost, light weight, good versatility and compact structure. It is mainly used for primary filtration of central air conditioning and centralized ventilation systems.

Medium efficiency air conditioner filter

The medium efficiency filter is mainly used for central air conditioning and centralized air supply systems. It can be used for primary filtration of air conditioning systems to protect the next level of filters and systems in the system. In places where air purification and cleanliness are not critical, the air treated by the medium efficiency filter can be sent directly to the room.

The medium efficiency air filter is mainly used for collecting 1-5μm particle dust and various suspended solids, and is widely used in various air conditioning systems. The main products are bag-type structure, the outer frame material is mainly made of aluminum alloy and galvanized steel plate, and the filter material is mainly made of non-woven fabric.

High efficiency air conditioning filter

The high-efficiency air filter can capture fine particles of 0.10.5um, mainly used in the microelectronics industry, precision instrumentation, medical and health, bioengineering, etc., generally as the end of the air for all kinds of clean rooms, clean tunnels, and efficient air outlets. Level filtering. The products are made of ultra-fine glass fiber filter material, hot sol as separator, special aluminum profile frame and so on.

From the above classification users can understand: in the central air conditioning, select the primary air conditioning filter and the medium efficiency air conditioning filter. At present, central air-conditioning is generally based on household or commercial use. There is no strict requirement for the filtration grade of the filter. In addition, the high-efficiency filter is expensive, so the air-conditioning filter is generally not recommended for central air-conditioning.
