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
- “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:
|Type of fiber||RK code||Temperat. restist. °C – continuous||Temperat. restist. °C – peak||Acid resistance||Alkali resistance||Hydrolysis resistance||Oxidation resistance|
|Polypropylene||PP||90||95||very good||very good||very good||partial|
|Polyphenylene Sulfide||PS||190||200||very good||very good||very good||partial|
|Advanced Fiber Blend||AB||240||260||good||good||good||good|
|Polytetrafluoroethylene||TF||250||280||very good||very good||very good||very good|
Filtering materials can be enhanced by the application of treatments appropriate to their working conditions:
|HydroTech||protection against moist or oily dust||presence of moist or oily dust, cement, lime, wood, energy industries, other|
|ConduTech||electrostatic discharge||explosive dust, ATEX zones, woodworking industry, food industry, metallurgy, cement industry|
|SparkTech||protection against sparks and glowing particles||sporadic occurrence of sparks and glowing particles, metallurgical industry, other|
|ResisTech||protection against aggressive chemical environment||presence of moist, oily, sticky dust, energy industry, thermal waste treatment, cement sector|
|MicroTech||special fine fibers for better dust separation and longer life||fine dust, low dust emission limits, cement, metallurgy, lime, power industry|
|MembraTech||surface lamination with ePTFE membrane for better dust separation, more effective cleaning and extended filter bag life||fine dust, very low dust emission limits, cement, metallurgy, chemical industry, thermal waste processing|
|PureTech||separation of very fine and hazardous dust particles||hazardous and carcinogenic dust, workplace air purification, wood industry|
|AluTech||special roughened filtration surface for better separation of fine dust||fine dust, aluminum industry fine dust, aluminum industry|
|FoodTech||food-safe filter medium and approved for direct food contact||food industry, pharmaceutical industry, food contact|
|ReleaseTech||Special surface for improved release of dust cake||waste incineration plants, cement, lime, power industry|
In addition, Remark-Kayser, based on the specific requirements of its customers, develops and realizes, in cooperation with a selected supplier, proprietary and individual filter media solutions to achieve the expected performance and to meet stringent emission requirements.
The highest quality of Remark-Kayser filter bags is achieved by an experienced and qualified production staff, modern machinery and strict quality control procedures.
