What are the classifications of air filters?

1. Primary filter

The filter material for the primary filter is generally non-woven fabric, metal wire mesh, glass wire, nylon mesh, etc. The commonly used coarse efficiency filters include ZJK-1 automatic winding herringbone air filter, TJ-3 automatic winding flat air filter, CW air filter, etc. Its structural forms include plate type, folding type, belt type, and winding type. Our common primary filters are plate filters and bag filters.

2.Medium efficiency filter

Common medium efficiency filters include M-I, II, IV foam plastic filters, YB glass fiber filters, etc. The filter materials of medium efficiency filter mainly include glass fiber, medium and fine porous polyethylene foam plastic and Synthetic fiber felt made of polyester, polypropylene, acrylic fiber, etc.

3. High efficiency filter

The commonly used high-efficiency filters are GB type and GWB type. The filter material is ultra-fine glass fiber filter paper, with very small pores. Very low filtration rate is adopted, which enhances the screening and Diffusion of small dust particles, so it has high filtration efficiency.

4. Ultra efficient filter

A filter with a named interval between U15-U17 is an ultra efficient filter, with a filtering efficiency of over 99.9995%.

Classified by form: plate filter, bag filter, V-shaped filter, filter equipment. These are detailed in our product introduction, mainly distinguished by the appearance of the product.

Classified by product characteristics: salt resistant bag filter, molecular filter, activated carbon filter, paint mist filter, oil mist filter, high-temperature filter, etc., mainly named and distinguished according to the specific usage characteristics of the product.
