Filter sleeves

Millimetric precision for a complete product

All filter bags are made with excellent quality materials, accompanied by a German BIA certification: polyester fibers, Nomex, Rayton, P84, polypropylene, acrylic, aramid, as well as a wide range of finishes (Teflon, hydro and oil- repellency, flame retardant, antistatic, anti-hydrolysis, non-stick just to name a few).

In addition to the filter bags, we also provide our customers with one complete set of accessories: from Venturi tubes (in plastic, aluminum or stainless steel), to rotating nozzles for cleaning the cartridges available in different heights, from differential pressure gauges for reading the pressure drop to precoating or fluorescent powders, up to the sleeve-tightening and bag-tightening bands.

What technologies do we use?

  • Automatic blade cutting with CAD/CAM.
  • Automatic tubing lines for cutting and tubularisation of felts and fabrics by heat sealing.
  • Line able to offer millimetric precision and very high reliability.
  • Manipulators for automatic folding and continuous packaging.
