Oil-free Screw Compressor and Screw BlowerROBOX SCREW

Highly efficient oil-free screw compressor and screw blower packages

  • Pressure up to 2,500 mbar (g)
  • Vacuum up to 300 mbar(a)
  • Capacity up to 10,100 m³/h

Low life cycle costs

The expense of a blower ownership is comprised of equipment, installation, energy, and maintenance costs. Equipment and installation are a onetime expense, while energy and maintenance are continuous costs of ownership. Robox Screw ensures a high level of efficiency (> 75%) within a wide blower rotation speed range reducing energy consumption. In addition thanks to its robust construction and use of minimum parts contribute to high reliability and long intervals between maintenance.

Quiet operation

The optimum efficiency of the internal compression,guaranteed by the innovative Robuschi rotorprofile, means less noise during the compressionphase. The low rotor rotation speed (max. 6,000rpm) and the absence of a step-up gear, along withspecial silencers and a noise-reducing enclosure(also available without sound hood - WL version),guarantee low noise levels from the blower,thus allowing installation in a variety of applications.

Robox Screw Low Pressure Screw Compressor

Maximum Energy Efficiency

The innovative and unique profile of Robuschi's rotors optimises the ratio between capacity and pressure thanks to the maximum performance of the internal compression. This increases the efficiency of the ROBOX screw unit. Its characteristics ensure high efficiency (>75%) in a wide range of rotation of the blower (from 100% to 25%), by reducing the energy consumption in any working condition. The high degree of efficiency of ROBOX SCREW plus its reduced maintenance costs guarantee a quick return on the initial investment (2 years on average depending on the application and the operating conditions).

Tailor made

The design of the ROBOX screw can be tailored in order to meet customer needs and match the application requirements.

Reliable

The precision engineered design and meticulous choice of each component of the oil-free screw blower together with a low operating speed, make the ROBOX SCREW extremely reliable. At the same time, the SENTINEL 2 and SENTINEL PRO control panels ensure optimum machine operation through the continuous monitoring of the operating parameters.

Vacuum adjustment

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.
