ROBOX Screw Low Pressure

ROBOX Screw Low Pressure Compressor Transparent

The ideal solution for wastewater treatment and other industrial applications thanks to its simple, user-friendly components.

Splash lubrication system

Extremely simple and compact, with minimal maintenance.


Silent operation

The high compression efficiency guarantees low noise operation. Using special silencers and the noise enclosure, sound pressure levels of below 70 dB(A)  can be achieved.


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. The characteristics of ROBOX screw ensure high efficiency (>75%) in a wide range of rotation of the compressor (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).



Robuschi's experience in the low pressure sector has enabled us to develop the ROBOX SCREW  in an innovative way, notably reducing the number of parts that make up the compressor itself. 



The  compressor offers a turndown capability in flow to meet the needs of the customer. It's also suitable for intermittent use with frequent stops and restarts to best satisfy the specific process requirements. The belt drive ensures the right capacity for the application, and also allows the installation of the motor most suitable for the power absorbed by the compressor (therefore operating at optimum efficiency).



The precision engineered design and meticulous choice of each component of the compressor 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.


Easy installation and maintenance

As it can be transported with a forklift and/or pallet truck, the ROBOX screw offers easy installation. Maintenance costs are reduced as every component of the ROBOX screw has a simple and robust construction, thereby guaranteeing a long working life. Thanks to the simple layout of the unit components, all routine maintenance tasks can be carried out from the front of the compressor, ensuring:

  • easy oil change
  • easy oil pressure adjustment and air filter replacement
  • easy drive belt replacement

Tailor made

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