PTFE Membrane Pleated Dust Filter Cartridge for Industrial Pulse Jet Dust Collector & Powder Coating Booths

Production Technology & Structural Composition

A complete dust filter cartridge consists of 5 core parts: functional pleated filter media, inner & outer anti-rust support mesh, metal/plastic filter end caps, EPDM elastic sealing gaskets and fixed tension bands.

Deep uniform pleating process maximizes effective filtration area without media extrusion, boosting dust storage volume and extending service life.
Hot melt integral bonding eliminates gaps between filter media and end caps, completely blocking unfiltered air bypass leakage.
Double-layer internal and external metal support skeleton withstands high-pressure pulse backblowing and long-term airflow vibration, preventing pleat collapse and cartridge deformation.
Multiple mounting structures (flange type, six-lug quick-disconnect, threaded top, twist-lock bayonet) support rapid tool-free replacement on all mainstream dust collector housings.

Main Filter Media & Applicable Working Conditions

1. Standard Spunbond Polyester Media

Cost-effective general grade, good air permeability, stable performance under dry normal-temperature environments.

Application: Woodworking dust, stone cutting, general workshop dry dust removal.

2. PTFE Membrane Laminated Polyester Media

Surface filtration design, dust barely embeds into fiber layer, easy pulse self-cleaning, ultra-high interception efficiency for submicron fine particles.

Application: Powder coating recovery, welding smoke, pharmaceutical fine powder, grinding ultra-fine dust.

3. Anti-Static Conductive Filter Media

Mixed conductive fiber to eliminate static sparks, explosion-proof for flammable dust working sites.

Application: Flour mills, chemical pigment powder, aluminum/magnesium metal dust processing.

4. PPS High-Temperature Resistant Media

Continuous working temperature up to 200°C, resistant to acidic flue gas corrosion.

Application: Boiler flue gas, metallurgical kiln waste gas, asphalt mixing plant dust collection.

5. Flame Retardant Polyester Media

Class B1 flame retardant performance, suppress dust combustion risks.

Application: Aluminum polishing, carbon black processing, combustible mineral dust workshops.

Core Competitive Advantages

✅ Ultra-High Stable Filtration Precision

Gradient fiber & PTFE membrane surface structure fully traps micro suspended particles, stable exhaust index to pass strict environmental monitoring inspection.

✅ Super Large Dust Holding Capacity

Optimized deep pleated layout extends service cycle, reduces replacement frequency and long-term spare parts expenditure.

✅ Low Airflow Resistance & Energy Saving

Smooth internal air passages reduce fan load and power consumption, lower factory daily operation costs.

✅ Excellent Repeated Pulse Ash Cleaning Performance

PTFE coated media prevents dust embedding, maintains consistent filtration efficiency after thousands of backblowing cycles.

✅ Reinforced Anti-Deformation Structure

Double-layer internal and external metal support mesh withstand strong pulse impact, no collapse or damage under long continuous operation.

✅ Diversified Mounting & Easy Installation

Universal modular interfaces match most domestic and imported dust collector brands, quick disassembly without professional tools to shorten maintenance downtime.

Wide Application Scenarios
