Product Overview

Polyester filter bags, also known as polyester dust collector filter bags or PE filter bags, are widely used in industrial dust collection systems.

Polyester needle felt provides a combination of mechanical strength, abrasion resistance, filtration performance and cost efficiency, making it one of the most commonly used filter media for industrial dust filtration.

Polyester filter bags are suitable for a wide range of dry dust collection applications where operating temperatures and chemical conditions are within the applicable range of polyester media.

They can be used in pulse jet baghouse dust collectors, industrial dust collectors, cartridge-to-bag filtration systems and customized dust filtration equipment.

Polyester Filter Bag for Pulse Jet Dust Collector

Polyester filter bags are widely used in pulse jet baghouse dust collectors.

During filtration, dust-laden air enters the dust collector and passes through the polyester filter bag. Dust particles are captured on the filter surface while clean air passes through the media.

When dust accumulates, compressed-air pulse cleaning removes the collected dust from the filter bags.

Proper filter bag selection depends on:

• Dust collector dimensions

• Filter bag diameter

• Filter bag length

• Cage dimensions

• Cleaning pressure

• Cleaning frequency

• Air-to-cloth ratio

• Gas temperature

• Dust characteristics

---

Polyester Filter Bag Surface Treatment

Different surface treatments can be used to improve filtration characteristics and dust release performance.

Singed Polyester Filter Bag

Singed treatment reduces loose fibers on the filter surface and provides a smoother filtration surface.

Calendered Polyester Filter Bag

Calendering creates a smoother and more compact surface that can improve dust release characteristics.

Water and Oil Repellent Polyester Filter Bag

Water and oil repellent treatment can be considered for applications involving moisture or oily dust.

Antistatic Polyester Filter Bag

Antistatic polyester media can be used for selected applications where static electricity control is required.

PTFE Treatment

PTFE treatment can be considered for applications requiring enhanced surface filtration characteristics.

---

Polyester Filter Bag for Cement Plants

Polyester filter bags are widely used in various cement and mineral processing dust collection applications.

Typical applications include:

• Cement grinding

• Cement milling
