Grid Pattern Anti-Static Polyester Dust Filter Bag CE RoHS Certified Washable for Industrial Pulse Jet Dust Collector System
Our grid antistatic PTFE membrane filter bag adopts polyester needle felt woven with carbon conductive grid fiber, compounded with imported PTFE microporous membrane. The grid conductive structure evenly conducts static electricity, effectively eliminate static accumulation and avoid spark risks for flammable dust. Adopting surface filtration principle, dust cannot penetrate into filter felt interior, ash falls off easily during pulse cleaning, preventing filter bag hardening and blockage. High filtration precision can trap ultra-fine dust below 0.2μm. Excellent chemical resistance against weak acid, weak alkali. Suitable for pulse dust collectors in powder coating, chemical raw material processing, plastic powder recovery and other explosion-proof required working conditions. We support customized sizes and multiple bag head styles to match different dust collector equipment.

Grid-pattern laminated anti-static filter bags | Core product selling points and advantages.
1. Grid Conductive Structure, Reliable Anti-static Performance
EN：Carbon fiber grid evenly distributed inside the felt, realize whole-surface static conduction, prevent static charge accumulation, avoid electrostatic spark, satisfy explosion-proof requirement for combustible dust workshop.
CN：滤布内部碳纤维方格均匀排布，实现全域导电，消除电荷聚集，防止静电火花产生，满足可燃粉尘车间防爆要求。
2. PTFE Microporous Membrane, High Precision Surface Filtration
EN：PTFE membrane forms a barrier on fabric surface, intercept ultra-fine dust above 0.2μm, dust stays on surface instead of penetrating into felt layer, achieve stable high filtration efficiency.
CN：PTFE微孔薄膜在滤布表层形成过滤屏障，拦截0.2μm以上超细粉尘，粉尘停留在滤袋表面不渗入毡层，持续保持高过滤精度。
3. Excellent Ash Release Performance, Not Easy To Block
EN：Smooth PTFE surface greatly reduces dust adhesion. Dust falls off rapidly during pulse jet cleaning, prevent filter bag clogging, stabilize system pressure drop and extend service life.
CN：PTFE膜表面光滑，大幅降低粉尘附着力；脉冲清灰时粉尘快速脱落，不易糊袋堵塞，稳定系统压差，有效延长滤袋使用寿命。
4. Good Chemical Resistance & Stable Temperature Resistance
EN：Base polyester material with PTFE composite layer performs well against weak acid, weak alkali and organic vapors. Continuous operating temperature up to 130℃, adapt to most industrial dust removal conditions.
CN：涤纶基材搭配PTFE复合层，耐弱酸、弱碱与部分有机烟气；长期使用温度可达130℃，适配绝大多数工业除尘工况。
5. Compact Weaving Process, High Tensile Strength
EN：High density needle punching technology, uniform fabric structure, strong tensile and wear resistance. Adopt high temperature sewing thread, avoid seam leakage under long-term pulse impact.
CN：高密度针刺工艺，毡体结构均匀，抗拉耐磨性能强；搭配耐高温缝纫线缝制，长期脉冲冲击下缝线不易开裂、杜绝缝线漏尘。
6. Flexible Customization, Perfect Matching Dust Collector
EN：Multiple bag top types including snap band, collar, flat top available. Custom diameter, length, bottom structure according to customer dust collector parameters, direct replacement for old filter bags.
Cleaning Challenges Q&A | Explosion-Proof Cleaning Conditions: Answers to Frequently Asked Questions
Q1：Combustible dust exists in powder workshop, ordinary filter bags accumulate static electricity and bring safety risks?
EN Solution：Common polyester filter bags have no conductive function, static cannot be released. Our grid antistatic filter bag adopts carbon fiber grid layout to conduct static evenly, avoid electrostatic spark, fully meet safety standards for flammable dust dust removal.
Q2：Ultra-fine dust penetrates into filter fabric, pressure difference rises rapidly and filter bags are blocked easily?
EN Solution：Ordinary needle felt relies on deep filtration, fine dust enters fiber gaps and causes blockage. PTFE laminated surface filtration keeps dust outside membrane, easy pulse cleaning, effectively slow pressure difference rising and reduce maintenance frequency.
Q3：Exhaust dust exceeds emission standard, hard to pass environmental inspection and faces rectification risk?
EN Solution：Conventional non-membrane filter bags cannot capture submicron dust. Our PTFE membrane filter bag achieves high interception efficiency for tiny particles, guarantee stable low emission concentration to satisfy environmental protection standards.
Q4：Hard ash cleaning leads to frequent shutdown maintenance and reduces production efficiency?
EN Solution：PTFE film surface has low surface energy, dust is difficult to adhere. After pulse blowing, most dust falls off automatically. Less shutdown maintenance time, improve continuous production capacity of workshop.
Q5：Slight acid & alkali flue gas corrodes ordinary filter bags, frequent replacement brings high cost?
EN Solution：PTFE composite layer provides excellent chemical resistance, protect base polyester felt from corrosive gas erosion, prolong filter bag service cycle and cut overall operating cost.
Q6：Standard filter bags cannot fit existing dust collector, equipment transformation brings extra investment?
EN Solution：We support full-size customization of grid antistatic PTFE membrane filter bags. Multiple bag mouth structures optional, produce strictly according to your drawing and dimension, direct installation without equipment modification.
