Product Description

Antistatic dust filter bag is made from high-quality polyester needle felt with conductive fibers to effectively dissipate static electricity. It offers excellent abrasion resistance, high mechanical strength, good air permeability, and efficient dust release, making it ideal for explosion-proof dust collection systems.

Compared with striped designs, the square Antistatic dust filter bag provides a more uniform conductive surface for stable antistatic performance. The tightly bonded polyester fibers create fine, even micropores that ensure reliable filtration while maintaining low airflow resistance.

The polyester needle felt structure gives the Antistatic dust filter bag excellent durability, flexibility, and filtration efficiency. With optional PTFE membrane lamination, it delivers longer service life, easier cleaning, and cost-effective performance for low-temperature industrial dust collection.

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.
