Becker DTLF 2.500 – oil-free rotary vane compressor
The DTLF 2.500 delivers 515 m³/h at 50 Hz (600 m³/h at 60 Hz) and works up to +1.5 bar pressure. Becker supplies it for several pressure stages with a matching motor: +0.8 bar with 15.0 kW (50 Hz) or 18.0 kW (60 Hz); +1.1 bar with 18.5 kW (50 Hz) or 22.0 kW (60 Hz); +1.5 bar with 22.0 kW (50 Hz) or 26.0 kW (60 Hz). Weight: 248 kg without motor. Dimensions: width × height 747 × 579 mm, length depending on the motor, pressure connection G 4".Dry-running rotary vane principle
The compressor works without oil in the compression chamber; there are no oil changes, and the compressed air produced is oil-free. An integrated inlet filter and a pressure regulating valve are part of the equipment; the motor drives the rotor directly.Versions and accessories
