PTFE Membrane Dust Collect Filter Cartridge 43x77
product description
The PTFE membrane dust collect filter cartridge 43×77 is a high-efficiency pleated cylindrical filtration element engineered for industrial dust collection systems requiring superior particulate capture performance. This compact air filter delivers exceptional filtration efficiency for fine and submicron dust particles in space‑constrained equipment.
The filter media features a PTFE membrane laminated onto a high-strength polyester non-woven fabric substrate. The PTFE microporous membrane is produced through a specialized mechanical stretching process that creates a uniform pore structure without altering the material's inherent properties. This advanced composite construction combines the mechanical durability of polyester with the surface filtration characteristics of PTFE, enabling surface filtration rather than depth filtration. Dust particles are captured on the membrane surface rather than penetrating the filter media fibers, preventing internal clogging and maintaining low and stable pressure drop over extended service life.

product FEATURES
-
* High Filtration Efficiency : The PTFE microporous membrane captures submicron particles with >99.99% efficiency for 0.3μm particles. The surface filtration mechanism ensures that even the finest dust—including welding fumes, laser cutting smoke, and pharmaceutical powders—is retained on the membrane surface.
* Surface Filtration. No Internal Clogging : Unlike conventional depth filters where dust penetrates and embeds within the media, the PTFE membrane captures particles on its smooth surface. Dust is easily released during pulse-jet cleaning, preventing pressure drop build-up and extending service life.
* Excellent Release Properties : PTFE has one of the lowest coefficients of friction of any solid material. Almost no substance adheres to the PTFE surface, ensuring that dust cakes release easily during pulse cleaning.
* Durable & Long Service Life : The rigid pleated construction withstands repeated pulse-jet cleaning cycles without deformation. The robust design ensures reliable operation with minimal maintenance and extended replacement intervals.
FAQ
Q1: What is the difference between PTFE membrane filters and standard polyester filters?
A1: PTFE membrane filters use a microporous PTFE layer laminated onto a polyester substrate, enabling surface filtration. Standard polyester filters rely on depth filtration where dust penetrates the media. PTFE membranes capture particles on the surface, preventing internal clogging, maintaining lower pressure drop, and providing easier cleaning during pulse-jet cycles.
Q2: What is the maximum operating temperature for PTFE membrane dust filters?
A2: Standard PTFE membrane cartridges operate continuously from -10°C to +120°C. For high-temperature applications, special grades can withstand up to 260°C continuously. Always consult the product datasheet for your specific model.
Q3: What filtration efficiency can I expect?
A3: PTFE membrane filters achieve ≥99.99% efficiency for 0.3μm particles. This high efficiency ensures compliance with stringent environmental emission standards, with outlet concentrations ≤5mg/m³.
