Filter bags

What are they?

Filter bags are responsible for separation of process dust in industries such as energy, building materials, metallurgy, chemical, food and pharmaceutical, tobacco and many others. Filter bags are the key components of filtration devices, whose task is to clean the gases coming from technological processes and prevent the atmosphere from being contaminated with undesirable dusts and organic and non-organic chemical compounds.

Remark-Kayser is a manufacturer of premium quality filter bags that meet the most stringent environmental legislation and individual customer expectations. Our products have been helping to combat air pollution on nearly every continent for nearly 30 years. Remark-Kayser’s expertise and patented technologies for manufacturing high-performance filter bags provide us with a solid leadership position among companies providing environmental protection technologies.


Highly efficient and modern production lines allow us to offer a wide range of design solutions for filter bags used in

  • “pulse-jet”, 
  • “reverse air” type filtration systems with fan assisted backflow cleaning
  • filtration units with a shake system.

Our filter bags are suitable for both vertical and horizontal installation of filter bags in filtration units.


The filter bags manufactured by Remark-Kayser are made of the highest quality filter materials from qualified suppliers worldwide. Highly demanding supplier evaluation and qualification procedures ensure on the one hand the high quality of our products and on the other hand a high degree of flexibility in terms of delivery times and the availability of almost any filter medium.

The basic materials used for the production of filter bags are the following needle felts and fabrics:

Values refer to the physical properties of the materials under standardized conditions.

Filtering materials can be enhanced by the application of treatments appropriate to their working conditions:
