This all pneumatic box will shut off the air supply to down-hole pumps when the tank, drum or IBC becomes full. This prevents overfilling of the drum and creating a spill. Ideal for LNAPL recovery projects.

Comprising of a separate control box and tank sensor, the control box can be mounted separately from the drum. The tank sensor is screwed into the drum and connected to the control box by a small air hose.
Being all pneumatic makes this inherently intrinsically safe.
Made in Australia.
