Duplex Self Cleaning Inlet Filter
Description
Rotorflush RF100 Duplex Filter – Technical Specifications
The RF100 Duplex doubles the capacity of the smallest of Rotorflush’s award winning filters. It gives a maximum usable flow (depending on conditions) of 60 litres per minute. The RF100 Duplex self-cleaning inlet filter is designed to protect surface mounted pumps and other equipment. Ideal for domestic use, light industrial applications, as a pond filter and for protecting water features.
The latest version of this highly adaptable and efficient dirty water filter now has an easy to use quick release enabling simple and fast filter mesh changes.
Ideal for:
- Small irrigation systems
- Protecting equipment from weed and debris
- Filtration of samples to online analysers
- Protecting newts and tadpoles as a pond pump filter
- Rainwater harvesting systems
- Industrial Process Filtration
- Ponds, fountains and water features
- Anywhere a flow of filtered fluid is required.


The Duplex self cleaning inlet filter uses a proportion of the pump’s output to drive an internal backwashing rotor. The twin jets of the cleaning rotor rotate at about 60 rpm in each filter head. They clean the whole screen every ½ second. Approximately 20 – 25% of the pump output is required to supply the cleaning rotor.
As the cleaning mechanism is on the filtered side of the screen debris in the water will not obstruct the mechanism.
For a larger capacity (up to 90 litres per minute) these filters can be combined to form a triple headed duplex version that uses the same technology and filter cages, giving 50% more the flow rate.
For a smaller capacity (up to 30 litres per minute) we offer the RF100-IND filter, a single RF100 filter that uses the same technology and filter cage, giving half the flow rate of the Duplex.
