2 Classification of air conditioner filters
Primary air conditioner filter
Scope of application: suitable for primary filtration of air conditioning systems. The primary air filter is suitable for the primary filtration of air conditioning systems, mainly used to filter dust particles above 5μm. The primary filter has three styles: plate type, folding type and bag type. The outer frame materials include paper frame, aluminum frame, and galvanized iron frame. The filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc. The net has double-sided sprayed wire mesh and double-sided galvanized wire mesh.
The characteristics of the primary filter are: low price, light weight, good versatility and compact structure. Mainly used:
Central air conditioning and central ventilation system pre-filtration
Large air compressor pre-filter
Clean return air system
Pre-filtration of local high-efficiency filtration device
High temperature air filter, with stainless steel frame, high temperature resistance 250-300 ℃ filtration efficiency
Filters of this efficiency are commonly used in primary filtration of air conditioning and ventilation systems, and are also suitable for simple air conditioning and ventilation systems that only require primary filtration.
Medium efficiency air conditioner filter
Medium-efficiency filters are mainly used in central air conditioning and centralized air supply systems. It can be used for primary filtration of air-conditioning system to protect the next-level filter in the system and the system itself. In places where air purification and cleanliness requirements are not strict, the air treated by the medium-efficiency filter can be directly sent to the user. The medium-efficiency bag filter frame produced by our company is in the form of cold plate spraying, galvanized sheet, etc. The filter material is non-woven fabric, glass fiber, etc., the filtration particle size is 1-5um, and the filtration efficiency is 60-95 % (colorimetry).
Medium-efficiency air filters are mainly used to capture 1-5μm particulate dust and various suspended solids. They are widely used in various air-conditioning equipment and air-conditioning systems, and are also used for intermediate protection of multi-stage filtration systems. This series of products are mainly bag-type structures, and the outer frame materials are: aluminum alloy, galvanized steel plate, and can also be made into frameless. The filter element material is mainly non-woven fabric.
1) Function: capture 1-5um dust particles
2) Type: frameless and framed bag
3) Filter material: special non-woven fabric or glass fiber
4) Efficiency: 60%～95%@1～5um (colorimetric method)
HEPA filter
High-efficiency air filters are mainly used in the microelectronics industry, precision instrumentation, medical and health, bioengineering, pharmaceutical and food industries and various types of clean rooms, clean tunnels, high-efficiency air outlets, purification workbenches, air showers and other purification equipment Air filter in the final stage. This product adopts ultra-fine glass fiber filter material, hot sol as separator, special aluminum profile frame, polyurethane two-component sealant, closed-cell sponge sealing strip, sprayed steel mesh uniform flow plate, etc. It is refined by strict process.
