We design and manufacture the following types of units: Vacuum and deep-vacuum units (which use a vacuum pump to create a near-full vacuum in the tank), Combi units (which use a high-pressure pump to clean dirt and debris from surfaces), Combi ‘HP’ units (combining two functions: a high-pressure system and a vacuum system – pressure 1000 bar), Combi sewer units (equipped with a vacuum pump that creates a near-full vacuum inside the residue tank to suck up wet materials) and Gully emptiers (a sewage collection vehicle for emptying septic tanks and street gullies. It can be retrofitted with a suction arm mounted on top of the tank).
