Filter Bags

We manufacture filter bags, filter cages and filter systems. The filter bag, which is indispensable for a cleaner air, is generally used in filter cabinets called jet pulse.

How do we choose filter bags?

The most important factor in determining the filter bag type is temperature. The higher the temperature at which the industry has worked, the higher the necessity of using a temperature resistant bag. Another factor in filter bag selection is acid, alkali, hydrolysis, solvent and oxide resistance. These parameters are important in determining the bag type according to the needs of the sectors. Bag types and temperature resistance values are given below.

Filter Bag Materials

Bags used in de-dusting and filtering systems are produced depending on operation conditions using felt fabrics made of %100 Polyester, %100 Polypropylene, %100 Homopolymere Acrylic (Dolanit), %100 Copolymer Acrylic, %100 Ryton (Polyphenylsulfide),%100 Meta-Aramid (Nomex),%100 Polyimide (P-84),%100 Teflon (PTFE), %100 Fibre glass and their quality is in accordance with European Norms.

Polyester Filter Bags

General Information

Polyester needle felt filter bag is a material commonly used in bag filter systems. Polyester filter bag is preferred because of its low cost and its smooth operation under many sectoral conditions. In particular, its solvent and oxide resistance is high, but its acid resistance is also moderate. There are weight values ​​such as 400, 500, 525, 550, 600 grams per square meter. The filter bag, whose content is 100% polyester, is internally textured and resistant to tensile and tensile stress.

By using the needling method in its manufacture, the fiber polyester material is turned into fabric and then dipped into hydrophobic liquids in order to gain water and oil repellency. Therefore, it is also called needle felt filter bag. The polyester filter bag, which becomes bright and smooth as a result of gassing on one side, ensures that the dust does not hold on. The moist and oily powder coming to the bag system is easily poured down with the help of pulses without holding onto the bag.

Polyester filter bags with a continuous operating temperature of 150 degrees work without any problems in sectors operating at normal temperatures. However, it is necessary to use bags such as nomex filter bags and P84 filter bags in systems operating at high temperatures and where the incoming air and dust are at a level that can melt the bags. Çözüm Filter A.Ş., an expert in the filtration sector. Do not forget to contact us to get detailed information about filter bags, which will be determined by the engineers according to the sector conditions.

You can get support from us on what material should be the material to be attached to your bag system, with the experience and expertise of many years in filtration. In case of need, we can come to your business site and make examinations and help determine the type of bag. Our solution team will guide you correctly based on the following points in determining the bag material:

- Sector

- The distance of the filter system to the production site

- Filter system capacity

- The temperature and dryness of the dust coming into the system.

Usage Area

• 150°C Polyester filter bags with a continuous operating temperature of 150°C are preferred in many sectors.
• Low Cost It is preferred because of its low cost and smooth operation in many sectors. Polyester filter bags providing high resistance to acids and oxides are strong against abrasion.

By applying hydrophobic impregnation, you can easily use the polyester filter bag, which has water and oil repellent properties, in sectors where dust comes in water and oily form. Bags with a gauze on one side prevent the dust from clinging to the bag by sliding easily from the surface.

Meta aramid (NOMEX) filter bags

General Information

Nomex filter bag should be preferred in sectors such as iron and steel melting plants operating at high temperatures, asphalt plants. This is because polyester filter bags can work at 150 degrees, while nomex (meta-aramid) filter bags work continuously at 200 oC.

The main material of this filter bag, known as nomex in the industry, is meta-aramid. This material, developed by Dupont, is sold under the Nomex® brand. Nomex (meta-aramid) products are produced in a way that does not melt, drip and does not catch fire in contact with air.

Acid, alkali and hydrolysis strengths are moderate, solvent and oxide strengths are good. It has variable weights between 400-525 grams per square meter and, like all other bags, it has hydrophobic impregnation application with water and oil repellent feature. Nomex filter bag is preferred in power plants and factories such as asphalt plants, ceramic, metal, waste enterprises, cement & lime plants, coal plants, power plants, foundries.

Many parameters are important in determining the most suitable material for the bag filter system. The most important of these is the degree of hot air and dust coming into the system. The operation of Nomex filter bags at 200 degrees is important for the sectors mentioned above. Polyimide P84 Filter Bag is recommended in sectors operating at a higher degree and in systems where the temperature of the air and dust coming into the system is higher due to the fact that the bagged systems are close to the operation area. The continuous operating temperature of these bags is 260 degrees and works smoothly in high temperature conditions.

Usage Area

• HIGH TEMPERATURES..In sectors with high temperatures such as iron and steel melting plants, asphalt plants, a high temperature resistant filter bag is needed to prevent the bags from melting with the incoming hot dust and air.
• 200°C..In order to meet this need, meta-aramid Nomex filter bags with a continuous operating temperature of 200°C (instantaneous maximum temperature 220°C) should be preferred.

Otherwise, the use of polyester filter bags that are resistant to lower temperatures will cause the bags in the system to melt

Antistatic Filter Bag

General Information

The production of antistatic filter bags is extremely important, especially because of the danger of dust generated in some sectors such as plastic and flour coming into the system under electrical charge. Although polyester filter bag products can be used in every sector, some sectors cause fires in the system as a result of dust and air reaching the system under electrical charge. Therefore, antistatic bag filters have been manufactured in order to make dust and air safe as a result of electrostatic studies. In this way, the possibility of fire has been eliminated and the focus is on the healthy operation of the system.

It prevents such dangers by being manufactured as conductive rods or conductive fiber strips placed in the bag. Antistatic filter bag production is carried out in this way and both the bags and the filter system are protected thanks to the conductive rods and the business continues production without any problems.

Usage Area
