What are they?
We offer a wide range of filtration media for production of filter bags for gas filtration used in various industry sectors. The materials we offer are mainly needle felts and fabrics of various characteristics. Moreover, they may be equipped with special treatment to increase strength or ensure improved performance of the materials.
Types of materials
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 to the standard material constructions indicated above, we offer you materials prepared especially for specific requirements such as characteristic working conditions, very low limits of dust emission into the atmosphere or other individual customer needs.
Thanks to a large storage area, the vast majority of standard material constructions are available immediately, and thanks to diversified methods of obtaining raw materials, special constructions designed for individual customers’ needs are realized in the shortest possible time.
Filtering materials in rolls are packaged for safe transport by road, sea or rail and can be stored in the customer’s warehouse.
