Becker VT 4.2 – oil-free rotary vane vacuum pump for rough vacuum
The VT 4.2 delivers 1.9 m³/h at 50 Hz and 2.3 m³/h at 60 Hz and reaches a vacuum of 400 mbar absolute. The single-phase motor delivers 0.09 kW at 50 Hz and 0.105 kW at 60 Hz. The sound pressure level is 56 dB(A) (50 Hz) or 58 dB(A) (60 Hz), the weight with motor 7.0 kg. Dimensions 222 × 156 × 166 mm (L × W × H), suction connection G 1/4".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 4.2 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
