PTFE Membrane Pleated Dust Filter Cartridge For Powder Coating Booths

Production Process & Internal Structure

A complete dust filter cartridge consists of pleated filter media, inner & outer galvanized/SUS304 stainless steel support mesh, upper and lower end caps, EPDM elastic sealing gaskets and tension fixing bands.

Deep uniform pleating maximizes effective filtration area, expands dust storage space and extends replacement cycle.
Hot melt integral bonding tightly combines filter paper and end caps without gaps, completely avoiding unfiltered air bypass leakage.
Double-layer internal and external metal support skeleton resists high-pressure pulse backblowing and long-term airflow vibration, preventing pleat collapse and cartridge deformation.
Multiple mainstream installation structures: six-lug quick disassembly, flange type, threaded top, bayonet twist-lock, compatible with most imported and domestic dust collector brands.

Main Filter Media & Applicable Working Conditions

Standard Polyester Spunbond Media

Cost-effective universal material, suitable for woodworking dust, stone cutting and ordinary dry workshop dust removal.
PTFE Membrane Laminated Polyester Media

Surface filtration design, dust not easy to embed, easy pulse self-cleaning, ultra-high efficiency for submicron fine powder, widely used in powder coating, welding smoke and pharmaceutical dust recovery.
Anti-Static Conductive Filter Media

Blended conductive fiber to eliminate static sparks, explosion-proof for flour mills, aluminum dust, chemical pigment and flammable powder production workshops.
PPS High-Temperature Resistant Media

Continuous working temperature up to 200℃, acid and flue gas corrosion resistant, used for boiler flue gas, asphalt mixing plant and metallurgical kiln dust collection.
Flame Retardant Polyester Media

Class B1 flame retardant performance, suppress dust combustion risk for metal polishing, carbon black processing.

Core Technical Parameters

Outer diameter: 160/320/325/350/490mm, oval, square and special shapes customizable
Height range: 300mm–2000mm as customer demand
Filtration efficiency: ≥99.9% for 0.3μm micro dust particles
Operating temperature: -30℃ ~ 200℃ (depends on filter media)
Support mesh: Hot-dip galvanized steel wire mesh / SUS304 stainless steel mesh
Sealing ring: Aging-resistant EPDM/silicone rubber, zero air leakage

Core Competitive Advantages

✅ Super High Filtration Precision

Gradient fiber and PTFE membrane interception tiny suspended particles, stable exhaust index to pass environmental supervision inspection.

✅ Large Dust Holding Volume

Optimized deep pleated layout reduces replacement frequency, lowers spare parts cost and production downtime.

✅ Low Airflow Resistance & Energy Saving

Smooth internal air passages reduce fan load and power consumption, save factory daily operation cost.

✅ Excellent Repeated Pulse Cleaning Performance

PTFE coating prevents dust embedding, filtration efficiency remains stable after thousands of backblowing cycles.

✅ Reinforced Anti-Deformation Structure

Dual metal support mesh bears strong pulse impact, no damage under long continuous operation.

✅ Universal Modular Installation

Diversified installation interfaces match domestic and imported dust collectors, quick disassembly without professional tools.

Wide Application Scenarios
