Polyester Needle-Punched Felt Filter Bag
It is a material widely used in polyester bag filter systems. Polyester needle-punched felt filter bags are preferred by many different industries because they are produced at low cost. While they have high solvent and oxidation resistance, their acid resistance is moderate. They are available in weight values such as 400, 500, 525, 550, and 600 grams per square meter. The filter bag, which has an inner texture, is made of 100% polyester. It is resistant to tearing and tensile stress.
Polyester Needle-Punched Felt
Polyester in fiber form is converted into fabric using the needle-punching method. After becoming a fabric, it is immersed in hydrophobic liquids such as water and oil to provide repellency. This process is also referred to as a needle-punched felt filter bag. As a result of singeing on one side, the polyester filter bag gains a bright and smooth surface, preventing dust from adhering to it. Moist and oily dust entering the baghouse system is easily discharged downward without sticking to the bag, with the help of pulse jets.
Information: Pulse valves are used in baghouse filters found in cement, ceramic, paint, feed, thermal power plants, concrete plants, detergent, glass, and iron–steel factories to shake off accumulated dust and prevent solidification of dust particles.
Polyester filter bags, with a continuous operating temperature of 150°C, work without problems in sectors operating at normal temperatures. However, in systems operating at high temperatures where incoming air and dust may reach levels that can melt the bags, special filter bags must be used.
POLYESTER NEEDLE-PUNCHED FELT FILTER BAG APPLICATION AREAS
Polyester filter bags with a continuous operating temperature of 150°C are preferred in many industries. They are favored due to their low cost and their ability to operate smoothly in most sectors. Polyester filter bags, which provide high resistance to acids and oxides, are also strong against abrasion.
Polyester needle-punched filter bags are used in Wood Factories, Flour Mills, Lead Factories, Metal Processing Facilities, Plaster Factories, and Polishing Plants.
As Tekspa, we manufacture all kinds of filter bags, filter cages, and filter system products. With our quality and experience in filtration, we cooperate with many of the world’s leading companies. We manufacture our polyester needle-punched felt bags in-house. For this reason, we can produce filters and auxiliary materials in any desired size and dimension for our valued customers. We operate with the principle of “Delivering quality products with quality service to our customers in the shortest time possible.” Since our establishment, we have continued our work uninterrupted with the positive energy we receive from our customers.
If necessary, we can visit your facility to conduct inspections and assist in determining the appropriate bag type. In determining the bag material, our solution team will guide you correctly based on the following criteria:
- Sector
- Distance of the filter system from the production area
- Filter system capacity
- Temperature of the incoming dust and whether it is dry
