Advantages of Bag Filter
01.
Efficiency
Thanks to the shape of the bags and the way the device operates, bag filters allow you to keep your work environment clean and free of contaminants efficiently.
02.
Application versatility
The structure of the filter bags is modular and adaptable. As a result, the sizing and shape of the filter can be adapted to the production layout and the characteristics of the line, offering an extremely versatile solution.
03.
Easy maintenance
Automated cleaning systems make filter maintenance easy, reducing the time and costs involved.
04.
Energy saving
Reduced resistance to the flow of air passing through the sleeves requires less energy for the overall operation of the system.

The Working Process of Bag Filter
Inertial impaction:
Larger particles, unable to follow the airstream, impact directly onto the fabric surface.
Interception:
Medium-sized particles flowing with the air contact and adhere to the filter fibers.
Diffusion:
Tiny particles move randomly due to Brownian motion, eventually contacting and sticking to the filter material.
Electrostatic attraction:
Some filter media utilize electrostatic charges to attract and hold particles.
Bag Filter: Filter Bag Material
Acrylic
Acrylic filter bags are best suited for high-temperature situations, as they can operate at up to 265°F (130°C).
Aramid Felt
Aramid, also known as aromatic polyamide or Kevlar makes for very abrasion-resistant filter bags. Filter bags can function at consistent temperatures as high as 400°F (204°C).
Fiberglass
Fiberglass shines at high temperatures and can operate at a whopping 500°F (260°C).
Polypropylene
Polypropylene filter bags are very resistant to chemicals and moisture, making them a great choice when dealing with corrosive or wet dust particles. They’re also very durable and are popular in pharmaceuticals, chemical processing, and food and beverage.
Polytetrafluoroethylene (PTFE)
PTFE, also known by its brand name Teflon, is a synthetic polymer that offers superior chemical resistance and low friction properties.
