The name says it all: VARIAIR Direct Screw (VADS)

VADS is the first direct-drive dry-running screw. With integrated speed controlling for demand-oriented applications and no need for a drive transmission, VADS is truly a Becker innovation!

This unit is able to fulfil the highest requirements for a wide range of applications. By entering the load and output into your customer system, the air supply system automatically and directly adapts to the given requirements. The frequency-controlled drive unit offers a wide control range with optimised demand matching. In addition to energy savings and higher efficiency, this also results in lower maintenance requirements. The non-contact, oil-free screw unit ensures high air flows with low pulsation and lends itself to "master/slave" operation. Integrated accessories include a non-return valve, intake filter, sound absorbers and ventilation/bleed system. An air blast cooler is also available.

The high-tech internal "workings" are reflected by the compact, modern design. All of the system components are integrated in an attractively designed, ready-to-use hood.
