Patented step regulation 

The three-fold step regulation of the cover determines the length of effectiveness of the integrated MB-ActiveCube, thus enabling durability to be controlled.

Integrated MB-ActiveCube  

The integrated MB-ActiveCube improves hygiene and prevents residue, crusting due to organic matter, urine residue and grease on the inside of the odour trap, and in the drain pipe.

Visual display indicator (unique patent) 

After the MB-ActiveCube has been removed, the red contact area beneath the transparent cover indicates that the odour trap on the waterless urinal needs to be replaced.

Vertically closing membrane system

The vertical membrane technology ensures absolute odour proofing. Under-pressure and over-pressure are compensated for by the membrane. No sewer gases can escape.

Functional description

Draining urine is fed through the funnel into the odour trap of the waterless urinal and then runs through the vertical membrane into the sewer system.

When there is no more urine flowing, the membrane closes and thus prevents any sewer odours from escaping.
