PTFE Membrane Pleated Cylindrical Air Filter Cartridge For Powder Coating Booth & Welding Fume Collector

Production Craft & Structural Composition

The complete cylindrical pleated air filter cartridge consists of folded filter media, inner support mesh, outer protective mesh, upper & lower end caps and EPDM sealing ring.

Precision Deep Pleating Process

Uniform, orderly pleats maximize filtering area within limited cylindrical space, increasing dust holding capacity and extending service intervals compared with ordinary non-pleated cylindrical filters.
Reinforced Double-Layer Support Mesh

Galvanized steel or SUS304 stainless steel inner and outer mesh prevents pleat collapse under continuous airflow and repeated pulse backblowing.
Hot Melt Integral Sealing

Filter media tightly bonded with end caps without gaps, effectively avoid air bypass and unfiltered air leakage.
Diversified Installation Methods

Open end, flange type, six-lug quick disconnect, threaded top and other interfaces, compatible with most domestic and imported dust removal equipment.

Optional Filter Media & Applicable Conditions

Polyester Spunbond Filter Media

Cost-effective universal material for general dry dust, woodworking dust, stone cutting waste dust.
PTFE Membrane Laminated Polyester Media

Surface filtration design, fine dust not easy to embed, excellent pulse self-cleaning performance, suitable for welding smoke, powder coating, fine chemical powder recovery.
Anti-Static Conductive Filter Media

Eliminate static sparks, explosion-proof for flour mills, aluminum dust processing and flammable powder workshops.
PPS High Temperature Resistant Filter Media

Continuous operating temperature up to 200℃, acid and flue gas resistant, used for boiler air intake, asphalt mixing plant dust collection.
Waterproof & Moisture-Proof Composite Media

Adapt high humidity, foggy and wet workshop environments.

Core Competitive Advantages

✅ Larger Effective Filtration Area

Three to five times more filtering area than smooth cylindrical filter elements of the same size, greater dust storage capacity and longer replacement cycle.

✅ Low Airflow Resistance & Energy Saving

Smooth pleated channels reduce wind resistance, lower fan load and cut long-term power consumption.

✅ Stable Pulse Cleaning Performance

Reasonable pleat spacing allows dust to peel off smoothly during backblowing, maintain stable filtration efficiency after repeated cleaning cycles.

✅ Anti-Collapse Reinforced Structure

Dual metal mesh support resists strong airflow impact, avoid pleat deformation and damage during long continuous operation.

✅ Zero-Leakage Sealing System

Elastic rubber gasket fits closely with filter housing, prevent raw air bypass and protect downstream equipment.

✅ Highly Customizable

Adjust diameter, height, pleat density, filter material and installation interface according to customer equipment parameters.
