PET Polyester Fabric Air Filter 140.6x133

The PET Polyester Fabric Air Filter is a high-efficiency filtration solution designed for industrial dust collectors, fume extractors, and ventilation systems. With its compact dimensions, this air filter delivers reliable particulate removal in space-constrained installations.

Constructed from premium PET polyester fabric, this filter offers an excellent balance of filtration efficiency, durability, and cleanability. Polyester fibers provide high durability and dimensional stability, resisting deformation under temperature changes and humidity . The material is naturally hydrophobic, which helps maintain stable performance in environments with variable moisture levels , and offers good resistance to weak acids and alkalis .

Our engineering team can accurately recommend filter media and surface treatment solutions based on your dust characteristics, temperature, humidity, and other parameters, ensuring optimal filtration efficiency and lifespan.

* End-to-end quality control, reliable product delivery: We implement end-to-end quality monitoring from raw material intake and production to finished product testing. Every filter element undergoes rigorous inspection before leaving the factory to ensure perfect fit and reliable operation in your dust removal system.

* Global market validation, widespread trust: Our products are sold in over 120 countries worldwide and operate stably in industries such as cement, mining, woodworking, and metal processing. Twenty years of consistent quality is the cornerstone of our global customer trust.

* Response is fast and flexible, and customization is a one-stop solution: Whether it is non-standard size or special treatments such as flame retardancy, waterproofing, oil resistance, and antistatic properties, our R&D team can respond quickly and provide full-process customization services from prototyping to mass production.

Q1: What is the difference between paper and polyester fabric media for this cartridge?
A: Paper media offers excellent filtration efficiency (F7-F9) at a lower cost and is suitable for general industrial applications. Polyester fabric provides higher durability, better temperature resistance (up to 120°C), and is often cleanable and reusable . Polyester also offers better moisture resistance and is available with various surface treatments.

Q2: Can this dust collect filter cartridge be cleaned and reused?
A: Paper media cartridges are typically disposable and not recommended for cleaning, as cleaning can damage the delicate fiber structure. Polyester fabric cartridges can often be cleaned using pulse-jet systems or, in some cases, compressed air backflushing. Some polyester cartridges with appropriate treatments may also be washable—consult our engineering team for specific recommendations.

Q3: What is the operating temperature range?
A: The standard operating temperature range is -20°C to +100°C . For applications requiring higher temperatures, please inquire about our high-temperature media options.

Q4: What surface treatments are available for this cartridge?
A: Depending on the media selected, we offer various surface treatments including:

Flame Retardant: For applications with fire safety requirements

Waterproof: For humid environments or moisture-containing air streams

Oil-Proof: For applications with oil mists or oily particulates

Anti-Static: For explosive dust environments requiring static dissipation

PTFE Membrane: For maximum filtration efficiency and easy cleaning
