Fabric Filter Bag

Fabric Filter Bag Production

Fabric filter bags are high-performance filtration components developed to prevent dust and particulate matter generated during industrial production from spreading to the environment. These bags are specially designed to be integrated into jet pulse filter systems and are used together with filter cages to both increase filtration efficiency and provide structural strength.

Filter bags are mounted externally over filter cages. This way, mechanical support increases and air flow in the system is properly directed. In jet pulse systems, dust accumulated on the bag surface is cleaned with pressurized air given through pulse valves. This contactless and controlled cleaning method provides long-lasting use and performance continuity without damaging the fabric.

Each filter bag is specially produced according to the technical requirements of the filtration system; considering capacity, diameter, height, and environmental conditions. As Fora filter, we produce filter bags and cages in special dimensions and forms that will provide full compatibility with your system.

Basic Criteria Considered in Production

Fabric filter bag production begins with technical analyses for the operating conditions of the system. The following parameters are considered in this analysis:

Type and model of filtration system
Production volume and generated dust load
Filtration capacity and physical dimensions of the system
Area where installation will be made (indoor/outdoor environment, horizontal/vertical placement)
Operating temperature range
Physical and chemical properties of dust (humidity, abrasiveness, content)

In light of this information, the correct filter media is selected to increase system performance and provide long-lasting use. The most commonly used materials include:

Polyester
Meta-Aramid (Nomex)
Antistatic Filter 
Polypropylene (PP)
Polyimide (P84)

All bag filters are specially designed and produced according to your facility's operating conditions. This way, the risk of incompatibility is eliminated and the filtration system operates smoothly.

How Are Fabric Filter Bags Produced?

The production process begins with converting fiber-based raw materials into dense, durable, and permeable filter fabric using the needle punching method. For this reason, these products are often referred to as "needle felt filter bags" in the industry.

The fabric converted to felt undergoes performance-enhancing processes:

Hydrophobic impregnation is applied to provide water and oil repellent properties
Glazing process is applied to one surface to reduce dust adhesion and improve air flow

The processed fabric is rolled and taken to the cutting-sewing line. Here:

It is cut according to order-specific dimensions
It is sewn with high-strength chain stitch machines
A leak-proof cap is sewn to the bottom, and a flexible collar that facilitates attachment to the filter cage is sewn to the top

Each filter bag whose assembly is completed is thoroughly inspected by the quality control unit, final cleaning processes are performed, and it is carefully packaged and made ready for shipment.
