Custom Polyester Fabric Air Filter Element 133x936
Product Description
The Custom Polyester Fabric Air Filter Element 133×936 is a high-capacity cylindrical filtration cartridge engineered for industrial dust collection systems, baghouse retrofits, and high-volume particulate control applications. This pleated polyester filter element is purpose-built to your exact specifications, delivering the filtration area, efficiency, and durability that standard off-the-shelf cartridges cannot provide.
Within a pulse-jet dust collector, dirty air flows from the outside through the pleated media to the inside. Dust particles are captured on the outer surface, forming a filter cake that actually aids in finer particle capture. Clean air exits through the center tube. Periodically, a high-pressure blast of compressed air pulses through from the inside, flexing the media and knocking off the accumulated dust cake, which falls into a hopper for disposal

Application Area
* Woodworking & Furniture Manufacturing : Captures sanding dust, sawdust, MDF fines, and wood flour from dust collectors in cabinet shops, millwork plants, and panel processing facilities. Pleated polyester cartridges offer longer life than traditional felt bags in wood dust applications.
* Metal Fabrication & Grinding : Removes metal fines, grinding swarf, and abrasive dust from high-volume metalworking operations. Polyester‘s abrasion resistance makes it ideal for handling coarse metal particles.
* Cement and Mineral Processing : Filters cement dust, limestone powder, gypsum, and mineral fines from finish mills, raw mills, bulk pneumatic conveying, and bin vent dust collectors.
* Plastics and Polymer Processing : Collects resin dust, regrind fines, and additive powders from compounding lines, extrusion processes, and pneumatic conveying systems.
* Coal and Power Generation : Filters pulverized coal fines, fly ash, and limestone dust from coal mill collectors and material handling systems.
* Powder Coating and Paint Booths : Captures powder coating overspray and paint booth particulate. PTFE-coated polyester provides excellent dust release and prevents sticking from sticky overspray particles.
* Recycling and Waste Processing : Removes dust from shredding operations, sorting lines, and material recovery facilities. Polyester‘s durability handles the high dust loading common in recycling applications.
* Metalworking Fume and Welding Fume : Captures fume particulates and fine metal oxides from welding, plasma cutting, and laser cutting extraction systems.

FAQ
Q1: Can this filter capture submicron particles like welding fume or pharmaceutical dust?
A: Standard polyester (spunbond or felt) captures down to 1‑3 microns with ~95‑98% efficiency, but not submicron particles. For submicron capture (0.2‑2 μm) at 99.99% efficiency, you need a PTFE membrane laminated to the polyester. The membrane also prevents sticky dust from blinding the filter.
Q2: Is polyester resistant to moisture and hydrolysis?
A: Polyester has good moisture resistance, but hydrolysis (chemical breakdown from high heat + high humidity + alkaline conditions) will destroy it. Keep below 100°C in wet, alkaline environments. For continuous wet or acidic service, switch to PTFE or PPS.
Q3. Can I clean and reuse this cartridge, or is it disposable?
A: Polyester cartridges are disposable. In-service pulse cleaning removes surface dust, but you should never wash or water-clean them – water causes shrinkage and hydrolysis damage. Replace when pressure drop stays high after pulsing or visible dust emission occurs.
