SUCTION UNIT
Suction is generated by two ejectors which generate, without the use of mechanical elements, a considerable vacuum inside the chamber, thus making suction possible.




A Venturi-powered wet vacuum that lifts heavy liquids and wet solids — driven entirely by your compressed-air line.
The WD AIR is a compressed-air wet vacuum engineered for the heavy end of industrial cleaning: large volumes of liquid, and liquid mixed with solids. Suction comes not from an electric motor but from a high-performance Venturi ejector driven by your compressed-air line, so there is no motor to service and the machine keeps drawing a continuous vacuum for as long as the air supply holds.
A dual, interchangeable filtration system lets one machine handle two jobs: fit the liquid filter for wet pick-up, or switch to the solid filter for dust and debris. The primary filter is an M-class polyester bag, backed by an additional anti-foam filter, and everything collects in a 130-litre high-strength steel container. A manual discharge valve drains the collected liquid without tipping or lifting.
Built from high-strength steel throughout, the WD AIR is engineered by Depureco as the manufacturer to keep working in demanding environments where lighter machines wear out — durability that pays back across the life of the machine. It carries CE marking and is intended for ordinary, non-classified industrial areas.
Suction is generated by two ejectors which generate, without the use of mechanical elements, a considerable vacuum inside the chamber, thus making suction possible.
Supplied with two washable filters, one polypropylene for liquid suction and one polyester for dust suction.
The material is collected inside a large coated steel container that is easy to move thanks to the 4 sturdy wheels.
A ball valve located at the bottom of the container allows the collected liquids to be easily discharged by gravity.
