FR512 Fluidised Reactor

The New Deltec FR 512 has been added to the range to bridge the gap between the popular 509 and 616 models. Its most common use is for fluidising Rowaphos however this quality reactor can be used for carbon or fluidising sand as a biological media.


The FR512 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.
