Becker T 4.40 DSK – oil-free rotary vane pressure/vacuum pump
The T 4.40 DSK works on the suction side and the pressure side at the same time: it delivers 35 m³/h at 50 Hz and 43 m³/h at 60 Hz up to ±0.6 bar relative. The installed motor power is 1.85 kW at 50 Hz and 2.2 kW at 60 Hz, the sound pressure level 68 / 68 dB(A). Weight: approx. 46–49.5 kg with motor. Dimensions: 619 × 324–328 × 293 mm. Suction and pressure connection G 3/4".Design
The pump runs dry, without oil in the pumping chamber. A vacuum regulating valve and a pressure regulating valve set the operating points on both sides; the inlet filter is integrated. The DSK version has a compressed air cooler and thus reaches ±0.6 bar instead of ±0.5 bar.Use
The pump provides suction air and blast air at the same time – for applications that need both together.Versions and accessories
- T 4.40 DV: version without compressed air cooler, max. ±0.5 bar, lower motor power and smaller dimensions
- External inlet filter: accessory, on request
- Acoustic hood SH 19: accessory, on request
