The BLACKBOX-270MAX is a portable, all-in-one waste disposal solution — a commercial-grade wastewater holding tank with an upgraded, Italian-technology automated pump system. 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 centrifugal 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.
Why BLACKBOX-270MAX
- Simple to install outside or beneath a building or recreational vehicle
- No moving parts to clog up or break
- Designed for minimal stress on all components and a long operational life
-
Manufactured in New Zealand from best-quality components
- Simple installation
Performance
The BLACKBOX-270MAX pumps fluids up to 250 m in distance or up to a 13 m head height. We recommend working on 200 m distance or 11 m head height — it's best to be conservative with toilet waste. The pump has a 40 mm flow diameter.

"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
