PTFE Filter Bag

Filter material
100% PTFE needle-punched felt fiber, single-filament/multi-filament structure; some products are equipped with ePTFE membrane surface to improve filtration accuracy and enhance anti-adhesion.

Surface treatment
It can be treated with hot pressing, singe, calendaring or PTFE coating to form a smooth, low friction, and non-dust-stick surface.
Edge-sealing form
The top is often equipped with PTFE or stainless steel sealing rings, which ensure reliable sealing through sewing or ultrasonic hot melting.

Filtration accuracy: 0.05–200µm is optional, and the common accuracy is 0.5, 1, 5, 10, 25µm.

Filtration efficiency: relative efficiency is about 85%; single filtration efficiency of coating/film layer can reach more than 99%.

Gas filtration fineness: PTFE membrane surface filtration efficiency of 0.2–3µm pore size reaches 99.99%.


Advantages and Features

Extreme environment resistance: resistant to high temperatures of 260–300°C, chemically stable at pH 1–14.

Efficient ash removal: Smooth surface has low adhesion, suitable for pulse/backblowing ash cleaning.

Low pressure drop design: high air permeability combined with coating film structure, effectively reducing system energy consumption.

Long service life: high mechanical strength, and can be used for more than 12,000 hours.


Application scenarios

High temperature industrial flue gas: filter bag dust removal such as power plants, steel plants, incinerators, etc.

Chemical process: strong acid, strong alkali or corrosive particles capture.

Food/Pharmaceutical: High cleanliness requirements, no pollution in the materials, no shedding particles.

Environmentally friendly emissions: Comply with strict emission standards, high particle filtration efficiency of PM0.2–3µm.
