Compressor Unit Compact Oil-Free Compressor Unit

Editor: Wolfgang Ernhofer

Robuschi's experience in low pressure for the waste water treatment and pneumatic transport fields is at the basis of the Robox Screw compressor unit, combining the features of the RSW “heart” – an oil-free screw compressor – with the consolidated characteristics of the Robox compact units.

The machine is a complete, flexible unit able to reach pressures of up to 2.5 bar (g) and capacity levels up to 10,500 m³/h. This is thanks to the sturdiness of the RSW air-end, with its bearings, seals and shaft oversized to allow for every possible use, even heavy duty.

In addition, the oil-free system avoids any risk of deterioration or pollution of the processed material. The unit available in a wide range of sizes and with different accessories according to the specific needs, is therefore a good choice for every type of pneumatic transport, waste water treatment and water treatment, and pressure/vacuum applications.

The energy savings are made possible by the profile of the rotors, improving the capacity-pressure ratio thanks to the maximum yield of the internal compression; this increases the efficiency of the unit which, in turn, reduces consumption.
