Polyester Filter Bags By Features
Features of Polyester Filter Bag
Polyester filter bags have excellent chemical and physical properties, and are economical and practical, suitable for medium and low temperature dry dust conditions. They are widely used for dust removal in industries such as cement, wood, and metallurgy.
Polyester fiber has excellent tensile and tear resistance, can withstand high mechanical loads, and is suitable for mechanical vibration cleaning.
Processing gases with high dust concentration and coarse particles has a longer service life.
Long term working temperature ≤ 130 ℃, short-term tolerance ≤ 150 ℃ (such as instantaneous high temperature flue gas).
Polyester is flammable, but its fire resistance can be improved through flame retardant treatment.
It can capture particles larger than 1 μ m and achieve a filtration efficiency of over 99% (depending on the weight and surface treatment process).
Dust is easy to peel off, with good dust cleaning effect, suitable for pulse back blowing dust cleaning system.
Polyester fibers themselves have moderate structural density, typically ranging from 200-300 L/(m ² · s) @ 200Pa.
Polyester has good acid resistance, weak alkali resistance, and resistance to organic solvents.
Customized Polyester Filter Bags
Filtedge specializes in creating 100% polyester needle felt filter bags for you, with standard weights of 300-600g/m², and can flexibly customize weight parameters according to your needs. We provide a variety of surface treatment processes such as PTFE coating, water and oil repellent, anti-static, etc., a variety of bag types such as round, star, flat, etc., standard diameters can be adjusted arbitrarily within the range of 100-300mm, and support your personalized customization needs for filter bag length and interface methods such as spring rings/flanges/slings, ensuring that each product can perfectly match your working conditions.
Chemical Properties of Polyester Filter Bags
The polyester filter bag you choose has balanced acid and alkali resistance (medium level). Although its hydrolysis resistance is relatively weak, it provides you with excellent antioxidant protection and excellent wear resistance. Under matching working conditions, it can continuously provide you with high-efficiency filtration performance, while showing excellent thermal stability, chemical resistance, moisture resistance and easy cleaning advantages, helping you easily cope with a variety of industrial filtration challenges!
Polyester Filter Bag Working Principle
The Filtedge polyester dust removal filter bag provides you with an efficient and reliable dust control solution through multiple collaborative filtration mechanisms. It can accurately intercept large particles of dust, such as cement powder and metal shavings, through the screening effect.
By relying on inertial collision, it firmly adsorbs mineral powder and coal ash in high-speed airflow onto the surface of the filter material. At the same time, for fine particles smaller than 1 micron, it combines diffusion adsorption and Brownian motion with the weak static electricity of the polyester itself to achieve deep capture.
It also has a three-dimensional mesh structure to deeply intercept small particles, ensuring that the filtration leaves no dead corners. Choosing our Filtedge polyester filter bag is to select a professional guardian for your dust removal system that is efficient, stable, and long-lasting.
Polyester Filter Bag Application
Filtedge dust removal filter bags can be used in a variety of industries, providing a full range of dust control solutions for your industrial production! In the cement industry, we specialize in solving the dust removal problems of kiln head and kiln tail, coal mill/cement mill dust collection and raw material crushing and screening dust; for the chemical and pharmaceutical fields, Filtedge can efficiently handle powder raw material recovery, reactor exhaust filtration and drying tower tail gas purification; for welding smoke, polishing dust and metallurgical smoke in metal processing, it can also be efficiently filtered.
In the field of energy and environmental protection, Filtedge can provide you with precisely matched filtration solutions for coal-fired boilers, waste incineration, and biomass power generation filtration, as well as food dust treatment, wood processing, plastic production, asphalt mixing, and other special working conditions.
We can provide you with Pulse jet filter bags, Reverse air filter bags and Shaker filter bags to meet your dust removal needs under different working conditions.
If you purchase regular polyester filter bags, the minimum order quantity is 10PCS; if you need customized filter bags, the minimum order quantity is 100PCS. We can also flexibly arrange production according to your needs.
The price of polyester filter bags will be determined by the weight of the fabric, the surface treatment process, and the size parameters such as the diameter and length of the bag. You are welcome to contact us and we will provide you with a detailed quotation based on your specific needs.
