There are 3 different sized combination filters. These all have the drum and the biological chamber built into the same unit.

Drawing on the experience and knowledge from our commercial development and collaborations we have transferred it to our range of smaller filter products to aid the modern water keeper.

The engineering and understanding of how filtration works was developed to produce the Combi range of filters. Fully curved base to eliminate corners that allow bacterial and debris build up.

Because of the clever design concept, the full length of the units (including under the drum unit), are utilised within the bio area. Thereby allowing the system to provide the maximum capacity to floor space without losing it to unutilised volume.

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. Option to utilise a forced wash at either 45 or 99 minutes (This is triggered only if an automatic wash has not completed within the specified time). 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.
Fully sealed nylon bodied water valve.
Low voltage so that only 12 volts DC 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.
77 micron stainless steel screen.
2 pin ancillary out from the control box facilitating you being able to utilise to your own requirements.
Extra deep waste tray with increased slope
