SUKO offers high‑quality PTFE filter bags made from 100% virgin polytetrafluoroethylene (PTFE). These bags are designed for industrial dust collection, flue gas treatment, and corrosive gas filtration. Thanks to PTFE’s exceptional chemical resistance, low friction coefficient, and thermal stability, they perform reliably even in harsh conditions where standard filter media fail.
All listed sizes are in stock and ready for immediate dispatch. You can select your required diameter and length, add to cart, and check out directly – no custom order or long lead time needed.
Each bag is manufactured with precision stitching, strict quality inspections, and consistent filtration efficiency. The non‑stick PTFE surface prevents dust build‑up, makes cleaning easy, reduces system pressure drop, and extends service life significantly.
Key Features
Superior chemical resistance – withstands most acids, alkalis, and organic solvents; ideal for chemical, waste‑to‑energy, and metallurgical applications.
High temperature tolerance – suitable for continuous operation up to 240°C (464°F) and short peaks up to 260°C (500°F) (depending on actual gas composition).
Smooth, easy‑to‑clean surface – low friction and anti‑adhesive properties improve pulse‑jet cleaning efficiency.
High filtration accuracy – effectively captures fine dust and meets stringent emission standards.
Standardised dimensions, ready to ship – popular diameters and lengths are kept in abundant stock for fast delivery.

Frequently Asked Questions
Q: Are these PTFE filter bags really in stock?
A: Yes – all sizes shown on this page are regularly stocked. If you need a size not listed, please contact us to check availability or alternatives.
Q: Can they be used in high‑temperature environments?
A: PTFE offers excellent heat resistance, but the maximum safe temperature depends on gas composition, moisture, cleaning frequency, etc. We recommend providing your operating conditions for a more accurate suitability check.
Q: What is the expected service life?
A: Lifetime varies with dust load, temperature, chemical attack, and cleaning cycles. Under suitable conditions, PTFE bags outlast standard polyester or polypropylene bags by a wide margin. Regular inspection is always advisable.
Q: Do you accept returns or exchanges?
A: Standard, unopened items in resalable condition can be returned within 7 days (subject to our policy). Used or non‑standard (custom) items are non‑returnable. Please confirm dimensions before ordering.
Q: Are there discounts for bulk purchases?
A: Yes – the unit price decreases with larger quantities. Check the tiered pricing on the store page or contact our support for a volume quote.
