Product Description

The antistatic dust filter bag is made of needle-punched felt, which reduces static electricity by adding conductive materials. It features a smooth surface, excellent abrasion resistance, and high strength. The fabric's splicing and twisting enhance permeability, allowing for quick water drainage and easy cleaning. Polyester antistatic needle felt is tightly woven, short-haired, and highly durable, making it perfect for explosion-proof dust collection.

Compared to stripe antistatic dust filter bags, the square antistatic dust filter bag offers a more uniform conductive surface. Made from polyester, it is designed for use at room temperature. The polyester staple fibers are densely interwoven, creating small, uniform micropores that provide excellent filtration.

Polyester needle felt, the primary material for bag filters, is produced by punching polyester fibers into a non-woven fabric. Coated polyester needle-punched felt bags are strong, elastic, and breathable. They are durable and effective at dust removal, making them a cost-effective filtration solution for low-temperature environments.

Advantages include:

- Uniform fiber distribution and large void filter for good air permeability.

- Low gas emission concentration with high dust collection efficiency.

- Resistant to blockage and deformation, easy to clean, and long-lasting.

Size:

There is no uniformly specified size standard for dust bag, and its size is determined according to the bag filter, the size of the flower plate hole and the length of the bag body.

Commonly used specifications are:

Calibre: ø120mm, ø125mm, ø130mm, ø150mm, ø160mm, ø180mm.

Bag length: 1m - 10m

Product Application

In the field of industrial dust removal, the dust has various properties, there are corresponding antistatic dust filter bags for different dusts, generally according to the temperature of the dust gas to choose the filter bag.

Room temperature or less than 130 ° C, commonly used polyester needle felt bags, 208, 729 filter bags.

Equal to or less than 150 ° C, the use of acrylic needle felt bag or fan of special medium temperature bag.

If it is greater than 150°C, use Flomax, PPS, Metas and so on.

If greater than 220 ° C, the choice of P84, PTFE, basalt, high silica and other filter bags.

When the water content is large and the dust concentration is high, waterproof and oil-proof dust bag (also known as anti-condensation filter media) or film-coated filter media dust bag is used.

If all kinds of coal dust, chemical dust, flour, aluminium powder, coke, carbon black, woodworking dust, etc., you need to use flame retardant antistatic dust filter bag.
