Details

specificities

1. Made of polyester, polyamide, nylon and other chemical synthetic fibers, according to the fiber diameter and density of different, non-textile, multi-directional, gradual rolling.

Needle method, with high air permeability, low pressure loss, high dust collection characteristics.

2. Made of composite fibers with different melting points inside and outside, the joints between the fibers are firm, tightly bonded and not easy to fall off.

3. Without adding any chemical adhesive, use hot melt fiber to mix and stick the coarse and fine fibers together, it is not easy to prolong combustion when it meets the fire source, and the flame retardant point is in accordance with the German industrial standard DIN53438F1.

4. Can be cleaned and reused

5. Can be installed with galvanized steel frame or aluminum alloy frame, can also be installed with metal back screen, can effectively support the filter to withstand high air volume is not easy to deform.
