Working principle

A mechanical cleaning mechanism removes retained matter from the filter surface for discharge. Performance depends on solids shape, adhesion and the fluid.

Construction & flow path

The filter surface, mechanical cleaner, drive and discharge path form the unit. Timed, differential-pressure or manual control is configuration-specific.

Applications & filtration duty

For duties with frequent element changes or online-cleaning needs. Verify removal and discharge, especially with adhesive or entangling solids.

Technical parameters

Use these specifications for selection. Materials, dimensions and operating conditions follow the selected model and agreed specification.

Selection information

  • Fluid & viscosity
  • Operating flow (m³/h)
  • Operating / design pressure (MPa)
  • Operating / design temperature (°C)
  • Connection size & standard (DN / in)
  • Contaminant characteristics
  • Differential pressure & service trigger (MPa)
  • Dimensions & service clearance (mm)

Model and configuration notes

Configuration for your application

Share the fluid, filtration goal, operating conditions and installation requirements. Existing models, nameplates or drawings help us review the configuration.

Information to prepare for an inquiry

Use this family’s selection priorities to share available operating conditions, equipment information or drawings.

  • Provide particle shape, adhesion, hardness and loading.
  • Confirm drive, power and control-trigger needs.
  • Review discharge volume, disposal limits and handling.

Operation & maintenance

Before opening, replacing elements or disassembly, stop and isolate under the equipment procedure, depressurize, drain and confirm zero pressure. Inspect cleaner wear, drive and discharge valves, and record pressure drop and discharge results. Automatic cleaning still requires planned maintenance.

Common operating inputs
  • Fluid and major composition
  • Target flow and operating pattern
  • Operating temperature and pressure
  • Contaminant form and target rating
  • Material, connection and space constraints
  • Maintenance frequency and existing equipment
