A gas ballast valve (included in the standard equipment from U 5.70 and optional also with higher flow rates) prevents virtually all condensation of vapours. The gas ballast allows a dosed volume of fresh air to enter the compression chamber. Condensation is minimized by adding unsaturated fresh air to the saturated suction air. Noise emission is also minimized by the standard enclosure.

Optional water cooling allows the vacuum pump to be used in high ambient or suction temperature conditions. In addition, this significantly prolongs the service life of the lubricant. Thanks to its variety of accessories, the pump can be adapted to the most diverse purposes.
