Becker VARIAIR VTLF 2.500/0-400 – variable-speed oil-free rotary vane vacuum pump
The VARIAIR VTLF 2.500/0-400 combines the dry-running VTLF 2.500 with a VARIAIR frequency converter (11.0–22.0 kW). It delivers up to 560 m³/h, reaches a vacuum of 250 mbar absolute and works in a frequency range of 30 to 60 Hz. The converter is supplied with 400–480 V ±10 % at 50 or 60 Hz (max. 32 A). Sound pressure level 80 dB(A), weight with motor and converter approx. 445 kg, dimensions 1550 × 747 × 712 mm (L × W × H), suction connection G 4", exhaust connection G 2".VARIAIR converter technology
The frequency converter matches the pump's output to the process: the pump delivers the pumping speed that is needed at that moment. This optimises the energy demand and keeps the vacuum constant even when demand fluctuates.Dry-running and easy to maintain
Like all VTLF pumps, the VARIAIR VTLF 2.500/0-400 works without oil in the pumping chamber. The vacuum safety valve and blow-off valve are fitted with silencers, and the inlet filter is integrated.Advice and service
