General Information about RF400 self-cleaning filters

RF400 filters are our most popular general purpose suction intake filters with a built-in self-cleaning mechanism that back-washes the filter mesh as your pump draws water.  They are designed for use with a surface mounted pump, which can also supply the backwash to the screen from its output. Alternatively, these screens can be made with a built-in submersible pump to provide a dedicated backwash to the mesh separately from your main pump.

Farmers, industrialists, laundries, conservationists, water industry professionals and renewable energy companies love an RF400 intake screen. This is because dirty water is screened at source, helping to prevent the intake, pump and any connected equipment from blocking. These 400 mm diameter self-cleaning intakes attach to the suction of surface mounted pumps, small enough to be portable, large enough to screen a ton of water a minute.

Here are some typical uses of these filters:

  • Irrigation and livestock watering
  • Cooling water screening for EPA Rule 316 (b) and Eel Regulations compliance
  • Filtration for spray bars and fountains
  • Screening industrial process water
  • Screening water when draining / flooding wetlands
  • Protecting open loop water source heat pump installations

Rotorflush RF400 self-cleaning suction intakes can be fitted with:

Nylon Mesh inserts

The filter mesh is made up of replaceable bias-cut nylon mesh offering a very clean filtration, ideal for sampling. The inserts are inexpensive and easy to replace.

Available in 60 micron, 115 micron or 300 micron

316 Sintered Stainless Steel Mesh

A robust 2 layer sintered steel screen that can be easily cleaned with a pressure washer. Ideal for screening water for heat pumps and other application with small tolerances.

Available in 50 micron, 100 micron and 315 micron

316 stainless Woven Mesh

A medium / coarse woven mesh screen providing low maintenance cycles, filters and screens with coarse mesh come fitted with rubber backwash jets which are suitable for handling larger particles. Ideal difficult water conditions.

Mesh apertures available: 1 mm, 2 mm and 3 mm

Perforated 316 Stainless Steel Mesh

A coarse screen providing ultra-low maintenance cycles, filters and strainers with coarse mesh come fitted with rubber backwash jets which are suitable for handling larger particles. Perforated mesh strainers are used where water is very dirty and screening needs to remove larger debris and particulate.

Mesh apertures available: 3 mm, 6 mm and 10 mm

Because they can be easily moved these 400 mm diameter RF400 screens can be installed in a number of ways.

The key thing to remember is to make sure that they have a lot of clear space around the mesh for the backwashed debris to be dispersed into, and that they are not sited in any silt or sludge build up below the filter.

RF400s can be suspended or attached to a float.  We also manufacture stands and guide rails to help site our products.

Separate surface or built-in backwash pump

Set-up using filter with separate dry backwash pump.................................Set-up using filter with built-in submersible backwash pump

Usually very little. Although they are self-cleaning all of our products will require a manual clean every once in a while.

The nylon mesh inserts are easily replaced, and stainless mesh can be cleaned with a pressure washer. How often depends on your mesh size and what you are filtering.

As a minimum we recommend the following:

  • Mesh up to 115 micron should be cleaned or replaced every 1000 hours of use
  • Mesh up to 315 micron should be cleaned or replaced every 5000 hours of use
  • Coarse mesh that is 1 mm or bigger should be inspected and cleaned every 6 - 12 months

Full maintenance guidelines can be found in the instruction manual available from the download link above.

All our products are guaranteed for a year.  Full details in our Terms and Conditions.
