Oil-free Screw Compressor and Screw Blower ROBOX SCREW

The optimum efficiency of internal compression, guaranteed by the innovative Robuschi rotor profile, means less noise during the compression phase. The low rotor rotation speed (max 6,000 rpm) and the absence of a step-up gear, guarantee low noise levels from the blower. The Robox is also enhanced with special silencers and a noise-reducing enclosure (also available without sound hood – WL version). These features also allow for easy installation in a variety of applications.

The innovative and unique profile of Robuschi's rotors optimises the ratio between capacity (volume) and pressure. This increases the efficiency of the ROBOX screw unit. Its characteristics ensure high efficiency (>75%) in a wide range of blower rotations (from 100% to 25%) in any working condition. The high efficiency of the ROBOX SCREW plus its reduced maintenance costs guarantee a quick return on the initial investment.

Control panels SENTINEL 2 and SENTINEL PRO ensure optimum machine operation through the continuous monitoring of the operating parameters. 

 

Technical informations

Rotors are designed with wide diameter shafts to reduce the deformation caused by internal and external loads, thereby ensuring the blower can work efficiently in even the harshest conditions. The bearings have an increased lifespan thanks to the reduced number of revolutions they have to make. The seals for  the gas conveyed and lubricating oil are also wear-free. The surface treatment of the rotors makes the RSW low pressure screw blower resistant to oxidation, meaning performance levels are consistently maintained.

New vacuum valve (patented) with high precision vacuum regulation (+/-2%) all over the working range avoids any waste of energy and it grants high reliability along with the required performance.

Features a traditional belt drive instead of a gear overdrive and, for applications with a reduced thermal speed, uses a simplified lubrication system.

Class 0 certification, according to ISO 8573-1
