Slot Tubes & Cylinders

Optima slot tubes and cylinders are made using a traditional triangular shaped profile which is wrapped around support bars and welded at each intersection resulting in filters with high mechanical strength combined with maximum open area.

Having a large variety of tooling diameters along with a selection of profile wire & support rod specifications gives Optima the flexibility to supply our clients high quality products that best suit their application or requirements.

In general, supplies of slot tubes and cylinders are used for liquid filtration in industries such as petrochemical, food processing and brewing. They are regularly implemented into OEM filtration systems for use in back wash facilities or automatic cleaning systems.

Radial Slot Execution Special Design

Radial Slot Execution Special Design

For filtration from the inside to the outside (FITO). The profiles are welded with the widest profile dimension outermost to the internal support bars. The inside working surface is interrupted by the path of support bars.

Radial Slot Execution Standard Design

Radial Slot Execution Standard Design

For filtration from the outside to the inside (FOTI). The profiles are welded with the widest profile dimension outermost to the internal support bars. The outside working surface is smooth.

Axial Slot Execution Special Design

Axial Slot Execution Special Design

For filtration from the inside to the outside (FITO). In this type of execution the slot forming profiles are parallel to the length of the slotted screen cylinder. The internal working surface is smooth. The support wires are wrapped from the outside around the slot, forming profiles that are connected to them by pressure welding.
