RF200A-E & RF200R-E Automatic Backwash Filter

Description

RF200A-E and RF200R-E Automatic Backwash Filter

Rotorflush RF200A-E and RF200R-E automatic backwash filter is a self-cleaning pump intake. It provides protection against blockage to dry-mounted pumps and other connected equipment. The RF200A-E and RF200R-E filters have a separate motor to drive their internal self-cleaning backwash, so that the cleaning mechanism is driven independently of the surface mounted pump.

They can be used where the pump output is variable without compromising the filter’s backwash. The motor continuously backwashes the mesh screen, blowing away anything that might cause it to block, whether your pump is pumping a low or high volume of water.

These are stainless steel dirty water suction intake filters with a capacity of up to 220 litres / minute (14 m³ per hour), capable of filtering from 60 microns to 6 mm.

The RF200A-E automatic backwash filter can be fitted with replaceable nylon mesh inserts; on average nylon mesh inserts need replacing every 5000 hours continuous use for 300 micron mesh, and every 1000 – 2000 hours continuous use for 60 and 115 micron mesh, although these maintenance intervals will vary according to water conditions.

The RF200A-E can also be fitted with stainless-steel filter mesh, and needs jet washing at similar intervals. The RF200R-E is designed for coarser filtration and can be fitted with 1, 2, 3 or 6 mm stainless-steel filter mesh.

When these filters are fitted with 2 mm woven stainless-steel mesh, the maximum flow rate that will comply with current regulations for Eel protection – at an intake velocity of 0.1 metres a second – is 192 litres a minute.  At their maximum flow rate, these filters comply with EPA Rule 316 (b) as their intake velocity does not exceed 0.5 ft per second.

The twin jets of the cleaning rotor rotate at about 60 rpm in each filter, clearing the whole screen every ½ second.  As the cleaning mechanism is on the filtered side of the filter mesh, debris in the water will not obstruct the mechanism, or affect the backwash pump.

For a larger capacity (up to 1000 litres per minute) please consider our RF400AR-E self-cleaning filter – up to 1000 litres per minute. All our filters and strainers use the same patented technology, providing efficient self-cleaning backwash to keep the filter mesh clear for a range of flow rates.
