The spraying booth filter cotton has various types and it generally means air filter cotton. This filter cotton can be divided into four types according to its materials: Synthetic fiber filter cotton, non-woven cotton filters, glass fiber filter cotton and activated carbon filter cotton. It is widely used in industries like automobile manufacturing repair industry, furniture manufacturing, industrial coating equipment, hi-tech electronics, military and aerospace.

Advantages of Spraying Booth Filter Cotton

1. Dense outlet side and low initial resistance
2. High dust holding capacity
3. Good fire retardant performance and long working life
4. The surface of synthetic fiber air filter cotton is reinforced by covered net scrim which is economical and reliable.
5. Moisture resistance and up to 100% relative humidity.
6. Activated carbon composite materials with dust collecting and deodorizing functions

Features of Spraying Booth Filter Cotton

Ceiling filter
The ceiling filter is mainly used in surface spray-paint industry, especially for final filtration in spray booth. The synthetic fiber air filter cotton is processed by high powered nonwovens of anti broken synthetic fiber. Due to the complete penetration of viscosity in media, dust particles cannot pass. To achieve the best spray results, the fully filtered air evenly spreads to form a laminar flow state.

Fiberglass filter

The fiberglass filter is composed of continuous monofilament fiberglass and it is progressively encrypted from the inlet side to the outlet side in fluffy state. The spraying booth filter cotton is used for heat recovery system. The inlet side is green and outlet side is white. Its good compressible properties can ensure its stability and strong nature. The filter media can store mist and dust.

Activated carbon filter

The filter bag is composed by high-adsorption activated carbon fiber and filter media which has high fine surface adsorption ability. The spraying booth filter cotton can get rid of the odor, sulfur dioxide and other volatile organic pollutants in the air effectively.
