Slotted tubes

Slotted tubes

The slotted grate is a light and very strong structure, which is obtained by winding a wire of triangular section. This design eliminates clogging of the slit and gives maximum throughput.

The direction of filtration can be implemented according to the principle:

• Outside - Inward 
• Inside Out 

Benefits of TEKO-SLOT slotted grates:

• no clogging of the FEL's slots due to a V-shape wire profile used in the screen structure;
• high mechanical strength of filtering elements allowing to withstand high loads;
• high corrosion resistance due to usage of high-grade stainless steel, including acid-proof and heat-resistant steels;
• high penetration rate of the filtered media due to a large filtration area and specific slot design;
• low hydraulic friction;
• even distribution of the filtered flow;
• guaranteed slot with ±0.015 mm tolerance;
• FELs with possible inwards and outwards filtration direction;
• efficient cleaning of the slotted filter surface by liquid or steam backwash, compressed air or chemicals with filtering surface geometry staying unchanged;
• manufacture of filtering equipment with slotted screens of various size and configuration, as well as filter units.
