RF600LW Self-cleaning Eel Screen & Intake Strainer

From £6,110.00 GBP

The RF600LW self-cleaning Eel Screening intake strainers provide industrial strength, low maintenance filtration for surface mounted pumps. They are coarse screened filters fitted with 1 mm - 6 mm stainless steel mesh screens. When fitted with 2 mm mesh they are an ideal Eel screen.

The RF600LWs are extremely tough stainless steel self-cleaning basket filters that protect pumps and other connected equipment from blocking and blinding when pumping dirty water.

Our award-winning self-cleaning mechanism in the filters provides a continuous backwash keeping the filter mesh free of weed, debris and other suspended solids, and their low intake velocity protects elvers, and other aquatic wildlife. Eel Screens are EA Eel Regulation compliant.

The RF600LWs can handle 160m3 to 730 m3 per hour.

RF600LW Self-cleaning Eel Screen


Description

RF600LW Self-cleaning Eel Screen & Intake Strainer

Rotorflush RF600LW Self-cleaning Eel Screen Intake Strainers have been specifically designed to meet regulations for the Protection of European Eels. Anyone pumping more than 20 m3 of water per day from rivers, lakes and reservoirs must ensure that measures are in place to protect eels and elvers. Our Eel Screens are designed for use on the suction hose of surface mounted pumps. They can also be used as gravity fed intakes as long as a pump is used to supply the backwash.

RF600LW Self-cleaning Eel Screen - how it works

 

The RF600LW Self-cleaning Eel Screen Intake Strainers can deliver a maximum of 160 m3/ hour – 730 m3 / hour through tensioned woven Stainless Steel mesh. The maximum flow rates for RF600LW screens for elvers and glass eel protection range from 81 m3 / hour – 366 m3.  This is so that the intake velocity of the water does not exceed 0.1 metres a second.

The RF600LW range of Eel screens can be fitted with 1 mm or 2 mm woven 316 Stainless Steel filter mesh with a 60% open area. The mesh is under tension and forms the body of the screen, maximising the mesh area.

Rotorflush self-cleaning eel screens use a proportion of your pump’s output to supply a feed to an internal backwashing rotor. The self-cleaning mechanism is powered by taking a ‘T’ off the already filtered pump output to supply the Rotorflush internal rotors. The cleaning rotors continuously backwash the mesh screen pushing away anything that might cause it to block.

Our self-cleaning Eel Screens can also be gravity fed but will then need a small backwash pump to provide a water supply to the backwash jets.

All our filters and strainers use the same patented technology, providing an efficient self-cleaning backwash to keep their filter mesh clear and to protect aquatic life.
