Product Details

DFR-3 FIBREGLASS FILTER ROLL 4" for spray booth use

Product Description

It is a high-arrestance filter made of high strength glass fiber with gradual density. Low compressibility keeps its shape and makes fiber purified air effectively. It can absorb the excess particles during paint-spraying operation and reducing pollution to the environment, makes the exhausted air more
environmental-friendly and inner circulating air more clean.

·Low initial resistance
·High separation efficiency
·Different color on inlet and outlet side
·Flexible
·Economical and practical
