The FR509 is better known as a Rowaphos reactor for its common use for fluidising Rowaphos however this quality reactor can be used for carbon or fluidising sand as a biological media.
The FR509 is a substantial fluidised reactor with a twist off bayonet lid to allow easy access for replacement of the media. The water is forced down a central tube and is returned back up through a diffuser plate. Sponges are fitted either side of the media section to retain the finer particles.
The lid is fitted with a tap to adjust the flow and two hosetails connected to unions for simple removal or to allow hard piping to be used.
Suitable for up to 1lt of Rowaphos or 1.2 lts of general media.
Flow rate :
Up to 500lt/hr (pump not supplied)
180 mm x 140 mm x 500mm high (including fittings)
*Please Note: The Inline Specialty Filters no longer include two filter sponges; rather they include one filter sponge for efficiency. These filters have been known to clog prematurely when using two sponges.
