Cylinders are manufactured by welding the ring formed support profiles on the longitudinal surface profiles. Each contact point between profiles are welded by a precise welding technology.
The ring-shaped support profiles are always outside Cylinders are suitable for filtering from in to out (FITO). The inner surface is always smooth.
- Support profiles are always outside
- Support profiles are always circumferential and ring formed
- Surface profiles are always longitudinal 
- Minimum 10 microns slots
- Flow from in to out (FITO)
- Wide range of the lenghts and diameters
