The BLACKBOX-85 is a portable, all-in-one waste disposal solution — a commercial-grade wastewater holding tank with an automated centrifugal pump system. It's an ideal way to move waste water from portable cabins, portable offices, tiny homes and semi-permanently sited RVs to a suitable drain on a suburban or rural property, building site, holiday bach and more.
How it works
Waste water from the kitchen, bathroom and toilet drains into the 85-litre holding tank. Inside sits a large-capacity 750 W centrifugal pump (15,000 litres/hour) 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-85
- Generally installed outside a building or recreational vehicle, but can also be installed inside a building or a boat
- No moving parts to clog up or break
- Designed for minimal stress on all components — problem-free service and a long operational life
-
Manufactured in New Zealand from best-quality components
-
Simple installation — no professional help (e.g. a plumber) required
Performance
The pump moves fluids up to 100 m in distance or up to an 8 m head height (manufacturer's specs). We recommend working on 80 m distance or 6 m head height — it's best to be conservative with toilet waste. The pump has a 40 mm flow diameter; connect 40 mm alkathene or 40 mm pressure pipe to the outlet.

Trusted across New Zealand
A local manufacturer of portable cabins has replaced over 100 of their customers' macerator systems to date with a BLACKBOX-type system. White, budget imported macerators are not comparable for performance.

"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
"The BlackBox is a great unit. Does its job well and very easy to install. Perfect for our tiny home. Tim was also awesome to deal with and got the unit to us very fast." — Johnnie
