The 'Drop In' Drums

The concept was to come up with a product that could drop in without a single modification to the original filter. It then had to be extremely easy to "wire up" and commission and then it had to be easy to maintain, with everything easily replaceable. It also had to have all the features needed to make a drum work but keep it within the chassis of the drum to allow it to be installed in almost any situation, no matter how tight.

All Models

  • The remotely sited 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. It also has 2 leads - one to plug in to the mains supply (110v and 230v, auto selectable) and one to plug in to the drum. Status of the unit is via 4 colour coded LEDs. We didn't think we could make it any simpler than that.
  • Low voltage, sealed water valves and drive units utilising an extremely low geared direct 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 12 watts and in full wash mode, use 35 watts. It is entirely possible to run it off a car battery for prolonged periods of time.
  • 58 micron stainless steel screen.
