The SPELFilter™ is a cartridge filter system that incorporates an upflow treatment process, through a spiral wrapped media configuration that maximises surface treatment area.  Flow through the filter cartridges utilises a self-regulating siphon which results in a low maintenance and high performance stormwater treatment. The automatic backwash at the end of each storm event further lengthens the lifespan of the filter.

The spiral wrapped media cartridge provides a significantly greater surface contact area to footprint ratio than other filters. With a flow rate of 2.83L/s per cartridge and underground installation, the SPELFilter provides excellent removal efficiency whilst maintaining site surface yield.
