PTFE Membrane PPS Filter Bag High Efficiency Low Resistance Ultra-fine Dust Removal Filter Sleeve
Our pure PPS needle felt filter bags are made of 100% polyphenylene sulfide fiber, featuring excellent high temperature resistance, strong acid corrosion resistance and superior hydrolysis resistance. With a continuous working temperature up to 190℃ and instant temperature resistance of 230℃, it stably adapts to high-temperature flue gas dust removal from power plant boilers and waste incineration. The uniform fiber structure achieves 99.9% high-efficiency interception of 0.3μm fine dust, with low air resistance and stable air volume. Inherent flame retardant property effectively avoids combustion risks. Optional PTFE membrane treatment further enhances surface dust release performance, preventing dust embedding and bag clogging. It maintains stable filtration performance in long-term acidic and humid working conditions, greatly extending service life and reducing overall equipment operation and maintenance costs.

Dust Removal Challenges Q&A: A Special Round of Questions and Answers on Incomplete Dust Removal
Q1：Ordinary filter bags cannot withstand high-temperature boiler flue gas, easy to deform and damage with short service life?
Conventional polyester filter bags can only withstand 130℃, and are prone to shrinkage, brittleness and failure in high-temperature flue gas above 160℃. Our pure PPS filter bag stably operates at 190℃ with instant 230℃ temperature resistance. It maintains complete fiber structure and stable filtration performance in long-term high-temperature working conditions, avoiding frequent bag replacement and downtime loss.
Q2：Strong acidic desulfurization flue gas corrodes filter bags, causing aging and poor long-term dust removal effect?
Ordinary filter materials are severely corroded by sulfur-containing flue gas, resulting in fiber breakage and dust leakage. Our PPS filter bag has inherent strong acid resistance, effectively resists erosion of sulfur dioxide and acidic condensate. It keeps intact filtration structure in harsh acidic working conditions, permanently solving incomplete dust removal caused by corrosion damage.
Q3：High temperature and high humidity flue gas causes filter bag hydrolysis, clogging and rising operating resistance?
Common filter bags are prone to hydrolysis and fiber degradation in humid and hot environments. Our PPS filter bag features excellent anti-hydrolysis performance, no swelling or pulverization in long-term humid flue gas. Equipped with surface anti-sticking treatment, it avoids dust adhesion and bag clogging, maintaining low-resistance and stable operation all year round.
Q4：Sparks from boiler and incineration working conditions bring fire risks to ordinary filter bags?
Our PPS filter bag has high oxygen index and inherent self-extinguishing flame retardant performance. It will not continue to burn when leaving the fire source, effectively blocking spark ignition risks. It solves both safety hazards and dust leakage problems, ensuring safe and stable operation of dust removal system.
Q5：Dust collector air volume decreases over time, ultra-fine dust cannot be filtered completely and exhaust emits smoke?
Ordinary filter bags have loose fiber structure, ultra-fine dust penetrates easily and embeds into gaps, causing increasing resistance. Our high-density PPS needle felt forms a dense deep filtration layer, intercepting 0.3μm fine dust completely. Optional PTFE membrane realizes surface filtration with zero fine dust leakage, fundamentally solving incomplete dust removal and exhaust smoke problems.
Q6:Frequent filter bag replacement in high-temperature corrosive conditions leads high operation costs?
Our PPS filter bag integrates high temperature resistance, acid resistance and hydrolysis resistance, adapting to various harsh industrial flue gas working conditions. Its service life is 2–3 times longer than ordinary filter bags. Reducing replacement frequency and equipment shutdown time, it comprehensively lowers long-term spare parts and maintenance costs.
