The BLACKBOX-270SUPERMAX is a portable, all-in-one macerator waste disposal solution — a commercial-grade wastewater holding tank with a commercial 1100 W cast iron automated sewage cutter pump (macerator with a tungsten cutter blade). It's the perfect way to move waste water from portable cabins, portable offices, baches, semi-permanently sited vehicles or general dwellings to a suitable waste or grey-water disposal location.
How it works
Waste water from the kitchen, bathroom, wash house and toilet drains into the 270-litre holding tank. Inside sits a large-capacity pump with a built-in float switch: when the fluid reaches a set level, the float automatically switches the pump on and the waste is pumped out through the 40 mm outlet pipe; when the level drops, the pump switches itself off. Fully automatic — no manual emptying.

Performance
The BLACKBOX-270SUPERMAX pumps fluids up to 300 m in distance or up to a 15 m head height. We recommend working on 250 m distance or 13 m head height — it's best to be conservative with toilet waste.

"We build portable accommodation and find the BlackBox to be a great unit. They are located outside the building so that if there is ever a blockage/leak or any other problem, there is no mess inside and the toilet doesn't have to be removed to get access like other macerator units. These are a great solution!" — Josh
