Feature
1.The filter cloth is based on the thickness of the whole filter layer and belongs to deep filtration
2. the depth of the whole filter layer is formed from the fiber into a three-dimensional porous structure, from the inside and outside to the outside
Dense, forming gradient filtering
3. high pollution capacity, long filtration life, low pressure difference
4.Repeated cleaning, economic benefits
Application
1) The fume and smoke treatment and particle removing system in metallurgy plant, alloy plant, steel works, moulding factories, fire-retardant factories and power stations
2) Fume filtration, tiny particle recycle and division of liquid and solid in aluminum electro analysis, tin, zinc, cooper and other rare metals
3) Smoke filtration in garbage burning, coal-feed boiler and liquidized laid boilers
4) Division of liquid, solid and tiny particle recycle in chemicals, coke, carbon, dyestuff, pharmacy and plastics
5) Asphalt concrete mixture, cements, ceramics, building materials, lime and plaster
6) Dust treatment, purification and collection in electronics, mining, foodstuff processing, flour and timber processing.

Q1: What is a polyester filter bag used for?
A1: Polyester filter bags are widely used in industrial dust collection, air filtration, and liquid filtration systems, such as in cement plants, chemical factories, food processing, and water treatment.
Q2: What is the filtration efficiency of polyester filter bags?
A2: The filtration efficiency can reach up to 99%, depending on the fiber density, surface treatment, and operating conditions.
Q3: What temperatures can polyester filter bags withstand?
A3: Standard polyester filter bags can withstand up to 150°C (302°F) continuous temperature, and peak temperatures up to 170°C (338°F) for short durations.
Q4: Are polyester filter bags resistant to chemicals?
A4: Polyester filter media have good resistance to mild acids, alkalis, and most organic solvents, but they are not suitable for strong acids or strong alkalis.
Q5: What are the available sizes and micron ratings?
A5: We provide a full range of sizes from #1 to #5 standard filter bags, and micron ratings from 1μm to 200μm. Customized dimensions and ring types (plastic, stainless steel, galvanized steel) are also available.
Q6: How should I clean and maintain polyester filter bags?
A6: They can be cleaned by reverse air, pulse jet, or manual shaking depending on the dust collector type. Regular cleaning extends service life and maintains filtration efficiency.
Q7: Can you produce customized filter bags?
A7: Yes. We offer OEM/ODM services according to your required size, material, temperature resistance, and filtration precision.
Q8: What is the typical service life of polyester filter bags?
A8: The lifespan varies from 6 to 24 months, depending on the working environment, temperature, dust type, and cleaning frequency.
