About the Material
Why Choose Polyester Filter Bags?
Polyester, commonly abbreviated as PE or PES in industrial filtration markets, is a widely used filter media for liquid filtration. Compared with many general-purpose materials, polyester offers a strong balance of mechanical strength, dimensional stability, abrasion resistance and operating temperature capability.
Polyester filter bags are especially suitable for processes where repeated flow, particle loading and higher operating temperatures demand more durability. Ince supplies standard and custom polyester liquid filter bags for bag filter housings used across a broad range of industries.
Good Heat Resistance
Suitable for higher process temperatures than many standard polypropylene applications.
Strong Abrasion Resistance
Handles particle-loaded liquids and demanding filtration cycles effectively.
Stable Dimensions
Maintains filter bag shape and structure under normal industrial operating conditions.
Wide Industrial Use
Suitable for water, coatings, oils, chemicals and manufacturing process liquids.
PE Media Performance
Designed for Durable, Consistent Filtration
Our polyester felt filter bags are engineered to capture suspended particles through depth filtration. The three-dimensional fiber structure provides high dirt-holding capacity while supporting stable flow rates.

Frequently Asked Questions
Polyester Filter Bag FAQ
What is a polyester filter bag?
A polyester filter bag is a replaceable filter element made from polyester media and installed inside a compatible bag filter housing. It captures suspended particles as liquid flows through the filter media.
What is the difference between polypropylene and polyester filter bags?
Polypropylene filter bags are often selected for broad chemical compatibility and cost-effective filtration, while polyester filter bags are commonly chosen when improved abrasion resistance, dimensional stability or higher operating temperature capability is needed.
What micron rating should I choose?
The correct micron rating depends on the target particle size, required product clarity, flow rate and process conditions. For general industrial filtration, 25, 50 and 100 micron grades are common starting points.
Which filter bag sizes are available?
Standard sizes include #01, #02, #03 and #04. Ince can also manufacture custom diameters and lengths for special housings.
Can you supply custom polyester filter bags?
Yes. Custom micron ratings, dimensions, rings, collars, seams, labels, cartons and private-label packaging are available.
