Easy to install due to compact, space-saving design with high reliability through a rugged design and low maintenance and wear due to optimally selected shaft speeds.
The built-in variable speed inverter drive technology on top of the pump ensures pressure setpoint control.
The GVS VSD⁺ series can be controlled and monitored with the Atlas Copco VSD⁺ app, offering live visualizations of pump performance via Bluetooth.
The key components within the element (or stage) have been optimized for efficient vacuum pumping at the lowest possible power consumption and optimal operating temperature.
Mounted directly onto the vacuum pump element, the oil mist separator utilizes multi step separation. The fine oil coalescing filter maximizes oil retention, allowing the vacuum pump to be located close to the point of use.
The inlet non-return valve protects the vacuum pump in the event of the pump stopping without the prior venting of the point of use.
