Technical parameters of polyester needle punched felt filter bags

May 12,2023

SFFILTECH polyester needle punched felt filter bag is a common dust collector filter bag with certain performance such as acid and alkali resistance, high temperature resistance, and wear resistance. It is commonly used in the field of flue gas emission treatment and is the most commonly used and economical dust collection filter bag. The technical parameters are as follows:

SFFILTECH polyester filter bag material: SFFILTECH usually uses polyester fiber as the raw material and is processed into polyester needle felt filter bags.

Filter bag specifications: SFFILTECH filter bag factories generally define specifications based on length and diameter. The length can be customized according to actual needs, and the diameter is usually between 100mm-200mm.

Thickness of needle punched felt filter bags: SFFILTECH filter bag companies can produce polyester needle punched felt filter bags of different thicknesses according to your needs, usually between 1.8mm and 3.0mm.

SFFILTECH polyester dust collection filter bag weight: SFFILTECH polyester filter bags are usually calculated based on the weight per unit area, usually between 450g/m2 and 800g/m2.

Polyester filter bag air permeability: refers to the volume of gas passing through the filter bag per unit time, and the air permeability of SFFILTECH filter bags is generally between 8-15m3/m2. min.

SFFILTECH needle punched felt filter bag breaking strength: refers to the force that the filter bag breaks when subjected to a certain tensile force. The polyester filter bag products of SFFILTECH filter bag company generally range from 800N/5cm to 2000N/5cm.

Temperature resistance of polyester needle felt bags: Polyester needle felt filter bags can generally withstand high temperatures of 120 ℃ -150 ℃, but temperature resistance is also related to specific processing technology.

In short, polyester needle punched felt filter bags have good wear resistance, acid and alkali resistance, and high temperature resistance, and are more cost-effective, widely used in various industrial fields.
