Bag filters

Bag filters

Bag filter is a very economic way to filter out suspensions and that’s the reason why it is so popular in many branches of the industry. It is commonly used in cleaning paints, lacquers, resins and very viscous liquids such as oils. Bag filters are very accurate and generate low investment and operating costs, especially when the liquid is not much contaminated.

Filter bags can be made of various materials depending on the client’s needs. Progressive density depth filtration delivers high efficiency (>99.98%) and long life.

Special housings for the bag filters make the change-outs really simple. Integral cover handle is easy to open and close.

While filtering out large amount of fluid, multi-bag filter housings are recommended. They can accommodate up to tens of filter bags.

Filter bags

Filter bags bring a new, high-performance alternative to applications requiring absolute filtration.

They are made of non-woven fabrics, such as polyester, polypropylene, nylon, etc.; woven fabrics, such as polyester multi- or monofilament, nylon monofilament, polypropylene monofilament, etc. or special fabrics, such as polypropylene melt blown micro fibre or polypropylene oil adsorbent felt.

Advanced media structure delivers both long life and absolute filtration. Progressive density design uses up to 12 layers of media which become finer and finer as fluid passes through. The result is gradual removal of contaminant without any single layer blinding prematurely.

Filter bags have performance efficiencies of over +99.98% absolute filtration. In many filtration applications of 1 micron and above.

They can be welded or sewn. Welded construction ensures that nothing bypasses the process media through holes in the fabric created from sewing the material.

Filter bag can be equipped with a flexible, chemically resistant seal which adapts to any filter vessel. A pressure-activated sealing lip responds to increases in differential pressure. As the pressure increases, the seal of the ring improves, guaranteeing bypass-free performance over all ranges of pressure, temperature and micron rating.

The elevated bag handles make removal quick and easy.
