Product Introduction
Our dust filter cartridge is the key filter element for industrial dust removal equipment, with complete specifications and reliable quality. Matched with Dust Collector Filter, Air compressor filter and other supporting filter consumables, it supports diversified dust treatment for different industrial working conditions. The filter cartridge adopts multiple filter media including ordinary polyester non-woven fabric, PTFE membrane coated polyester, anti-static polyester, water & oil repellent polyester and wood pulp fiber paper. It features filtration precision from 5 to 10 microns, high dust collection efficiency up to 99.99%, good air permeability and stable mechanical strength. Multiple surface treatments such as smooth finishing, water & oil repellent coating, PTFE membrane lamination and conductive dipping are available to adapt to high temperature, humid, oily and explosive dust environments.
Working Principle
The dust-containing airflow passes through the outer surface of the filter cartridge. Dust particles are intercepted and captured on the surface of the filter medium under the effect of inertial collision, diffusion and adsorption. Clean air penetrates the filter medium and flows into the inner cavity of the filter cartridge, then enters the clean air duct. When dust accumulates on the outer surface and the pressure drop rises to the set value, pulse back-blow compressed air is injected into the inner cavity of the filter cartridge. The instantaneous airflow shakes off the attached dust, and the dust falls into the ash hopper to realize automatic cleaning, so the filter cartridge can maintain continuous filtration capacity.
Filter Media Types & Features
Ordinary Polyester Non-woven Fabric Made of polyester fiber, filtration precision ≥5μm. Suitable for powder spraying, sandblasting, pigment, wood processing, cement and general dust filtration conditions.
PTFE Membrane Coated Polyester Non-woven Fabric Adopts imported PTFE membrane coated filter material. It delivers high filtration accuracy and easy dust cleaning by pulse back-blowing. The service life can reach 1–2 years under normal working conditions. Widely used for welding fume, sand casting, pharmaceutical, cement, tobacco and textile industry for coal dust control.
Anti-static Polyester Non-woven Fabric With anti-static aluminum film coating on the filter surface, the conductive aluminum layer prevents static sparking. It is specially designed for metal dust filtration and explosion-proof dust removal sites.
Water & Oil Repellent Polyester Non-woven Fabric Fluorine resin coating on fiber surface provides water repellent, oil repellent and anti-fouling performance. Dust is not easy to stick to the surface, and back-blow cleaning is much easier. Ideal for humid, oily, high dust concentration environments, also works well for dry large particle dust.
Wood Pulp Fiber Filter Paper Composite wood pulp fiber filter paper. It is widely applied for gas turbines, air compressors, sandblasting, tobacco, fly ash and bleaching industry filtration.

Installation & Maintenance
Check the sealing rubber gasket before installation to avoid air leakage and dust bypass.
Keep the pulse back-blow system working normally to reduce dust clogging.
Replace the filter cartridge timely when the pressure difference exceeds the normal range.
Cooperate with Dust Collector Filter and Air compressor filter for graded filtration to extend the service life of the main filter cartridge.
Avoid sharp objects scratching the filter medium during installation and replacement.
FAQs
Q1: What is the difference between PTFE coated filter cartridge and ordinary polyester filter cartridge?
A: PTFE membrane coated filter cartridge has ultra-fine surface membrane, higher precision, better stripping performance and longer service life, suitable for fine dust such as welding smoke.
Q2: Which filter cartridge should I choose for metal powder with explosion-proof requirement?
A: Anti-static polyester filter cartridge is recommended, which can prevent static electricity and avoid spark risks.
Q3: What is the maximum temperature resistance of the dust filter cartridge?
A: Ordinary polyester medium can work up to 120℃; special high-temperature filter material can reach 200℃.
Q4: Can the filter cartridge be cleaned repeatedly?
A: It can be cleaned by pulse back-blowing on site. For severely clogged or damaged filter media, direct replacement is required.
Q5: Is this filter cartridge compatible with self-cleaning air filter equipment?
A: Yes, it can be used as internal filter elements for self-cleaning air filters, air compressor intake filters and cartridge dust collectors.
