It houses all the same technology as a normal BD 300 but has a built-in Bio-Chamber suitable for up to 100lts of Fluidised Media or any other biological Media that is preferred for example Jap-Mat or Ceramic Media.

As standard in the Burtons range, these drums come with a 60-micron screen, and a weatherproof auto-control box, in which you can wire in and control both your UV’s and your water pumps.

These drums feature 3 x 110mm inlets and 3 x 110mm outlets. Plus 2 x 110mm outlets before the bio section.

The BD 300 Combi can handle up to 35,000ltr per hour through the drum section. We would recommend taking no more than 15,000 ltrs from the bio section outlets, if you want more flow we have added outlets on either side to pull the additional flow.
