Cement Woodworking Dust PTFE Membrane Polyester Bag High Breathability Long Service Life Filter Sleeve
Our PTFE membrane laminated polyester filter bags adopt high-quality polyester needle felt as the base material, compounded with imported ePTFE microporous membrane through high-temperature lamination process. Combining the high toughness and wear resistance of polyester fabric with the ultra-high filtration accuracy and non-stick performance of PTFE membrane, it realizes absolute surface filtration and completely changes the defect of deep dust embedding of ordinary polyester filter bags. It stably intercepts 0.3μm ultra-fine dust with filtration efficiency up to 99.95%, achieving ultra-low emission standards. The smooth membrane surface provides excellent dust release performance, ensuring thorough pulse cleaning without residual clogging, maintaining long-term low air resistance and stable air volume. With excellent moisture and dust adhesion resistance, it perfectly solves the problems of bag blinding and incomplete dust removal in humid fine dust working conditions. It is the best cost-effective upgraded filter material for normal-temperature industrial dust collectors.

Key product selling points and advantages.
1. Absolute Surface Filtration, Zero Fine Dust Leakage
The compact ePTFE microporous membrane covers the fabric surface completely, realizing pure surface filtration. All ultra-fine dust is intercepted on the membrane surface, solving the problem of fine dust penetration and exhaust smoke of ordinary polyester filter bags.
2. Ultra-smooth Non-stick Surface, No Dust Embedding & No Bag Clogging
The PTFE membrane has ultra-low friction coefficient and non-stick performance. Dust cannot embed into fiber gaps. Pulse jet cleaning removes dust cake completely, permanently avoiding pressure drop rise and bag blinding.
3. High Filtration Efficiency, Meet Ultra-low Emission Standard
Accurately intercepts 0.3μm fine dust particles with 99.95% ultra-high filtration efficiency. Effectively controls workshop floating dust and exhaust emission, easily passes strict environmental protection inspections.
4. Excellent Moisture-proof Performance, Adapt to Humid Working Conditions
The integrated membrane layer isolates moisture and humid dust, prevents damp dust from adhering and hardening on the filter bag surface, and solves the failure of ordinary filter bags in high-humidity dust environments.
5. Polyester Base High Toughness, Wear-resistant & Long Service Life
High-density polyester needle felt base has strong tensile strength and wear resistance, resists frequent pulse impact and sharp dust scouring, no fiber shedding or damage, longer service life than ordinary filter bags.
6. High Cost Performance, Upgraded Replacement for Ordinary Filter Bags
EN:With PTFE ultra-high filtration performance at ordinary polyester price, it is the most cost-effective upgraded solution for normal-temperature dust removal, reducing long-term replacement and maintenance costs.
Explanation and answers regarding incomplete dust removal.
Q1:Ordinary polyester filter bags cannot filter ultra-fine dust completely, causing exhaust smoke and unqualified environmental emission?
Traditional polyester felt relies on deep fiber filtration, and submicron fine dust easily penetrates loose fiber gaps. Our PTFE membrane polyester filter bag adopts absolute surface interception structure, with 99.95% ultra-high efficiency to block all fine dust. The exhaust gas is clean and meets ultra-low emission standards, permanently solving the problem of incomplete dust removal.
Q2:Filter bags are prone to dust adhesion and hardening in humid dust conditions, resulting in frequent bag clogging?
Ordinary polyester filter fabrics have strong dust adsorption force, and humid dust is easy to embed and harden. Our PTFE membrane has excellent water resistance and non-stick performance, moisture cannot penetrate the membrane surface, and dust will not bond and harden. Pulse cleaning is always thorough to keep stable air volume.
Q3:Dust collector resistance increases and air volume decreases after long-term operation, restricting production efficiency?
The core cause of rising resistance is residual embedded dust in ordinary filter bags. Our PTFE membrane filter bag has a smooth and dense surface with no dust embedding. Each pulse cleaning completely removes dust cake, maintains low and stable operating resistance, and ensures continuous and efficient operation of the equipment.
Q4:A large amount of ultra-fine dust from woodworking, stone and cement cannot be intercepted by ordinary filter bags?
Ordinary polyester filter bags have large pore size and low precision, only blocking large particles. Our PTFE microporous membrane has uniform tiny pores, specially targeting 0.3μm ultra-fine dust and floating powder. It thoroughly solves the problem of workshop dust flying and fine dust leakage.
Q5:Frequent dust cleaning brings poor effect and high manual maintenance cost?
Ordinary filter bags have poor dust release performance, dust residue causes repeated clogging and frequent cleaning. Our PTFE membrane filter bag has excellent dust peeling performance, one-time thorough ash removal, reduces cleaning frequency and effectively saves labor and power consumption costs.
Q6:Want ultra-low emission filtration effect without high cost of full PPS or full PTFE filter bags?
Our PTFE membrane polyester filter bag perfectly balances ultra-high filtration performance and cost. The polyester base ensures toughness and wear resistance, while the PTFE membrane ensures ultra-low emission effect. It is the most cost-effective upgrade solution for normal-temperature dust removal, greatly reducing long-term operating costs.
