The CAP12 is ideal for the domestic or commercial market; and is a perfect solution for up to 12 inhabitants (e.g. small commercial premises or 7 – 10 bedroom residential).

The CAP12 uses a bio-media systems and delivers a pollutant removal level of 96.2%, combating common problems associated with small packaged domestic plants such as media blockage and inadequate oxygen supply.

The CAP12 model can easily be installed using a 2.5-tonne mini digger resulting in simple, cost effective installation with minimal damage to the surrounding area.

The model has a quiet running compressor housed under the flat lid, therefore the operational use is virtually silent. It also dramatically reduces long term operating costs as, the only component that requires maintenance is the compressor.

The system is odourless as the waste is purified with micro-organisms during the treatment process, and is therefore an acceptable addition to the garden, or anywhere where it is housed near to the required working area.
