Dry-running rotary vane principle

The pump is designed for continuous operation in the rough vacuum range. Its self-lubricating vanes run without oil – there is no oil change, and the conveyed air stays free of oil. This makes the VT 4.8 a solution for applications that require a clean environment. The operating point can be set with the integrated vacuum regulating valve.

Design and equipment

The motor drives the rotor directly via the motor shaft – this keeps the pump compact and makes installation easier. The robust design is intended for long running times even under demanding conditions, and maintenance can be carried out on site.

• Large integrated inlet filter
• Combined vacuum regulating and safety valve
• Noise-optimised blow-off valve
• Base
