Slot Tubes

Optima slot tubes 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.
