Product description

Small inlet filter series

The small inlet filters series consists of 3 sizes 30, 60 and 90 liters per minute. Named single, duplex and triplex.

The inlet filter, (strainer) uses a proportion of the pump’s output to supply a feed to the internal backwashing rotor. The twin jets of the cleaning rotor rotate at about 60 rpm, cleaning the whole screen every ½ second. Approximately 20 – 25% of the pump output is required to supply the cleaning rotor.

The smallest capacity, up to 30 liters per minute is on offer, a single RF100 filter, the strainer uses the same technology and filter cage, giving half the flow rate.

The middle capacity up to 60 liters per minute these filters can be combined to form a double-headed duplex version that uses the same technology and filter cages, giving twice the flow rate.

For a larger capacity (up to 90 liters per minute) these filters can be combined in a triple headed version that uses the same technology and filter cages, giving 50% more of the flow rate.
As the cleaning mechanism is on the filtered side of the screen, debris in the water will not obstruct the mechanism.
