PTFE(Teflon) Filter Bags
PTFE dust filter bags—often known in the market as Teflon® filter bags—represent the highest tier of performance in industrial filtration. They are chosen for processes where temperatures, chemistry, or moisture levels exceed the limits of any other filter media. Unlike polyester, PPS, aramid, or even fiberglass, pure PTFE felt maintains its mechanical strength and surface stability even in extremely harsh environments.
PTFE fibres have an exceptionally low surface energy, which makes them naturally non-stick. In real baghouse operation this translates into cleaner bags, lower residual dust on the surface, and far more stable pressure drop during high-load periods. Plants running corrosive flue gas, high humidity, or highly variable operating windows rely on PTFE because it simply does not degrade the way other materials do.
Pure PTFE felt maintains a smooth, low-energy fibre surface that resists dust adhesion. This allows the dust cake to form evenly and release cleanly during pulsing, resulting in consistent emissions and predictable pressure drop even when gas chemistry fluctuates.
Where aramid or PPS would begin to weaken, PTFE stays in its comfort zone. In processes running between 200 and 240 °C—especially those with moisture spikes—PTFE provides unmatched thermal stability and maintains its mechanical strength far longer than other industrial felts.
PTFE is the only mainstream filter media that is effectively immune to acids, alkalis, solvents, and corrosive gas components. This resistance makes it ideal for waste incineration, chemical reactors, fertilizer production, and carbon black plants where flue gas chemistry can change from hour to hour.
Because PTFE fibres do not bind dust, the residual layer left after pulsing is extremely thin. This reduces fan load, improves airflow uniformity, and helps operators maintain stable production rates, even with high dust loading or variable humidity.
In real-world plants, PTFE bags often run for multiple years, even in gas streams that quickly destroy other filter materials. Reduced change-outs mean less downtime, lower labour intensity around the baghouse, and more predictable performance planning.
Each PTFE bag we manufacture is matched to the cage design, air-to-cloth ratio, chemical exposure profile, and cleaning system of the actual baghouse. Every production batch is checked for weight, permeability, membrane integrity, and seam strength—ensuring what arrives on site is tuned for your process, not simply “a PTFE bag.”

Pure PTFE filter bags handle continuous service close to 240 °C with peaks around 260 °C, while the fluoropolymer fibre structure resists acid dew point, strong alkalis and aggressive solvent vapours in harsh flue gas.
Optimised PTFE membrane and bag construction help keep stack emissions at or below 10 mg/Nm³, supporting the strictest environmental permits and cleaner plant operation.
From waste incineration and chemical processing to high-temperature mineral kilns, PTFE filter bags offer consistent emissions control in any application involving corrosive, high-acid or high-alkali flue gases.
Incinerators expose filter media to some of the harshest gas conditions: acidic vapours, corrosive compounds, temperature swings, and variable moisture. PTFE’s chemical inertness and stable surface performance keep emissions within strict limits year-round.
Fine powder, high temperatures, and abrasive particles demand a felt with both stability and release properties. PTFE bags maintain low pressure drop and minimise carryover, essential for product recovery and stack compliance.
Reactors, dryers, and chemical handling systems generate fumes that degrade most textiles. PTFE withstands acids, solvents, and oxidizers without losing strength, helping baghouses remain reliable between scheduled shutdowns.
