For specific applications, the dedusting material is given a corresponding post-treatment, such as:
- Antistatic treatment: for fine and explosive substances
- Flame retardant treatment: for applications where glowing particles are present
- Anti-hydraulic treatment: to combat humidity and consequent clogging, skid resistance and degradation
- Opticatch treatment: smooth top layer for higher efficiency and resistance to clogging and abrasion in cases of high particulate matter and emission.
Filter bags, hoses & folders
You will find filter bags in every industry. From the paint industry to the food industry and the automotive industry. Where previously more expensive filtration systems were required, nowadays a filter bag is cost effective and easy to use. And all of this of excellent quality. At Euro Manchetten, we make filter bags, hoses and envelopes to order for any industry and any application in our own workshop.
By keeping up with the latest materials and developments in our production techniques, we can provide a wide range of possibilities with regard to cloth filtration. Besides the well-known cotton filter bag, envelope and hose, we also make filter bags from polyester and polypropylene needle felt and from aramid seam felt with special coatings.
Bag filters are often used in air treatment installations and ventilation systems. They are available in all standard sizes and filter classes (G1 - F9) but are also made to order. Depending on your process, you can choose from glass fibre or synthetic bag filters.
We also supply hybrid bag filters with a filter cloth that consists of a combination of a glass fibre and synthetic medium,
If there is limited space available for a filter a compact filter can offer a solution. By applying a large number of minipleats a very large filter surface is achieved which can still be filtered efficiently. Compact filters are standard supplied in glass fibre, but are also available in synthetic materials. The frame in which the filter is mounted is usually made of plastic because this provides an optimum seal in the filter frame. However, they can also be manufactured in wood, metal, or stainless steel.
Materials & Coatings
Various filter materials are used for filtration. For specific applications, the material for the dedusting products is given a corresponding post-treatment. A short summary:
Polyester fibers, Nomex, Rayton, P48, Polypropylene, Acrylic, Aramyde with an extensive possibility of finishing such as:
- Teflon coating
- Water and oil repellent coating
- Flame retardant coating
- Antistatic coating
- Hydrolysis coating
- Non-stick treatment
To improve filtration, the materials can undergo various treatments.
- Calendering: using hot rollers the material is heated and pressed on one or both sides. This affects the surface, reducing air permeability and improving dust filtration.
- Laminating: seam felt with a PTFE membrane that ensures very fine filtration and good cleaning of the filter surface.
- Nanotechnology: a treatment which gives the filter material self-cleaning properties. This also increases the service life.
- C.I.P. filter material with special treatment for food applications. An FDA-EC 1935 certification with declaration of conformity is also issued.
- High temperature resistant filters, mainly polyimide P84 or PTFE fabric with PTFE needle felt or PTFE laminate.
In addition, a standard is used, the BIA standard, to determine the filtration in working conditions. Government emission requirements also provide sufficient information to make a choice
