Self-Cleaning Filters

Supplier: Absolute Filters

Absolute self-cleaning filters have been designed specifically to provide efficient filtration of virtually all liquids, including those of high viscosity, whilst minimising both disruption of flow and liquid loss during the element cleaning process.


There is no operator contact with the process fluid. The high quality stainless steel wedge wire (or perforated) element is highly effective in removing contaminant particles as small as 50 micron (µm).

Cleaning is carried out by rotating the element against fixed scraper blades which remove debris from the surface of the element. This in turn is drained from the base of the filter.

The filter is available for either manual or fully automatic electric or pneumatic operation. The range of optional control devices make it particularly suitable for continuous processes and for service with high contamination levels.

Benefits of Self-Cleaning Filters

  • No operator contact with liquid during cleaning operation.
  • Minimised product loss - during both process production and system cleaning.
  • Increased quality output - minimum disruption to product flow.
  • Reduced contamination - less possibility of accidents or operator exposure to the fluid.
  • Reduced maintenance costs - automated units can eliminate manual cleaning.
  • Environment friendly - enclosed design with minimal flushing losses.

Main Features of Self-Cleaning Filters

  • Simple efficient cleaning process which minimises disruption to flow
  • Minimal amount of liquid loss during cleaning process

Options of Self-Cleaning Filters

  • Filters available in the following materials:
  • Head: stainless steel, cast steel, cast iron or SG iron Bowl: stainless steel or mild steel
  • Range of automated control devices available.

Note 1: Working pressure is stated at 100°C. To verify suitability of this equipment above this temperature or below 0°C, please contact our help desk.

Note 2: Whilst alternative seal materials e.g. EP, PTFE are available and can be used to offer a wide range of chemical compatibility and working temperatures up to 250°C, it is recommended that such applications are again discussed with our help desk.
