We have now released 3 different sized combination filters. These all have the drum and the biological chamber built into the same unit.
The controller has start / emergency stop buttons and a knob allowing you to change the length of wash. LED indicator shows the length of time between washes in minutes. Status of the unit is via 4 colour coded LEDs.
Low voltage, sealed water valves and drive units utilising an extremely low geared brushless motor drive system mean that only 12 volts is anywhere near your pond water.
Designed to run without a noisy and power hungry wash pump in most circumstances (they are available if required). On standby the unit can use less than 2 watts and in full wash mode, use 45 watts. It is entirely possible to run it off a car battery for prolonged periods of time.
