Polytetrafluoroethylene (PTFE) Dust Filter Bags

Using the finest fiber material possible in the market and high-speed modern needling equipment, we manufacture our own filter media for our dust filter bags guaranteeing the highest quality, reliability, and consistency

A wide range of surface finishes and chemical treatments that aid in the collection and release of the dust from the bags

Ultrasonic welded seam for increased efficiency and reinforced mechanical strength

Our laboratories are equipped with sophisticated testing equipment used to analyze and evaluate all aspects of your process and application

Custom fabricated bag designs to meet the unique needs of your bag house installation

Generally used for severe chemical environments at high temperatures

Excellent resistance to acids, alkalies, hydrolysis, oxidation, solvents

Abrasion resistance is generally superior to protein fibers but not as good as most synthetics

Requires a 20 verticalwire minimum support cage when used in tubular bag form

Expensive-excellent chemical and thermal resistance

Continuous operating temperature 500oF (260°C)
