FEL filtering elements (slotted drainage caps)

FEL filtering elements (slotted drainage caps)FEL filtering elements (slotted drainage caps) are the basic elements of the internal drainage distribution assembly of the water-treatment filters. The majority of internal drainage distribution assemblies produced by "TEKO"-FILTER represents a so-called "caps system" consisting of radial pipes or a false bottom equipped with FEL filtering element (slotted drainage caps).

FEL filtering elements (slotted drainage caps) are commercially produced in 4 versions:

  • version 1 — FEL with filtering surface facing upwards;
  • version 2 — FEL with filtering surface facing downwards;
  • version 3 — FEL with filtering surface facing downwards and upwards;
  • version 4 — FEL made of "TEKO-SLOT" wire-wound frame;
  • version 4-T — titanium FEL
  • version 4-P — plate-type FEL filtering elements;
  • version 4-Pl — plastic FEL slotted drainage caps;
  • version 4-PP/N — combined FEL made of stainless steel and plastics.

 

FEL Filtering elements are manufactured of 10X18N9 (AISI 304), 12X18N10T (AISI 321), 10X17N13M2T (AISI 316Ti) stainless steel, titanium, as well as of various plastics in compliance with the Specifications.

FEL filtering elements (slotted drainage caps) that have been produced by "TEKO-FILTER" company since 1992 are successfully used in filters of various purposes in different industry sectors: from large electric power stations and metallurgical plants to public and housing utilities and petrochemical industry.

 

Core benefits of FEL filtering elements (slotted drainage caps) produced by "TEKO-FILTER" company:

  • high corrosion resistance due to a high quality plastics and stainless steel used for FELs production;
  • high mechanical strength of the slotted drainage caps proved by the test results and operation characteristics;
  • resistance to high temperatures - FEL may be applied for the filtrate with the temperature up to 120°С;
  • relatively large cross-sectional area in combination with small sizes - surface usage efficiency factor is in the range of 0.36-0.46 depending on the slot width;
  • low hydraulic friction which may be ignored when calculating the drainage distribution assemblies' parameters;
  • guaranteed slot width ±0.05 mm;
  • any configuration of the slotted drainage cap’s attachments can be implemented: welded connections, threads of any types and sizes, collet fixture;
  • easy installation;
  • possibility of application in the food industry according to required Hygienic Certificates.

The slot width is essential in terms of designed application. Standard slot widths are 0.2 and 0.4 mm; 0.1 - 1.2 mm slot widths may be produced upon request.
