Polyester Needle Punched Felt is a non-woven fabric material made of polyester (polyester fiber) through a needle punching process, which is widely used in the fields of filtration and industrial dust removal.

●Technical parameters

●Specifically:
Material: Mainly made of polyester fiber, which has the characteristics of high strength, wear resistance, corrosion resistance, and good temperature resistance (generally applicable temperature is around 120°C).
Manufacturing process: Through the needle punching process, that is, a large number of fine needles are used to repeatedly puncture the fiber layer, so that the fibers are entangled and fixed to form a felt-like structure, which has good mechanical strength and stability.
Structural features: No woven wire, overall uniformity, uniform pore distribution, good filtering performance and air permeability.
●Main uses:
Industrial dust removal filter material
Used as the filter layer of dust removal filter bags and dust removal filter elements, it is widely used in power plants, steel plants, cement plants, chemical plants, etc.
Filter material
Applicable to liquid filtration, air filtration, oil filtration and other fields.
●Advantages:
Relatively economical price, high cost performance
Good mechanical strength, wear resistance
Stable filtration efficiency
Flexible processing, easy to form
●Disadvantages:
Limited high temperature resistance, usually not suitable for environments above 120℃ (special high temperature resistant polyester can be used at slightly higher temperatures)

●FAQ:

Q.What is the filtration efficiency of the room temperature dust bag?
A.The filtration efficiency of the general needle felt material is more than 99%. If the coating technology (PTFE coating) is used, the efficiency can reach more than 99.9%, which is close to "zero emission".

Q.What are the common specifications of the room temperature dust bag?
A.Common diameter: Φ130mm, Φ160mm, Φ180mm, etc.
Length: Commonly 2m, 2.5m, 3m, can also be customized
Installation method: round mouth (steel ring type), spring ring, flange mouth, etc.

Q.What should be paid attention to during use?
A.Avoid excessive temperature to prevent bag burning
Regularly check whether the bag cage and filter bag are damaged
Avoid blockage caused by oily or sticky dust
Keep dry to prevent condensation and bag sticking
