DBS 45 - 55 KW

The superior components selection and the compact internal layout make this range of compressors stand out in terms of high performance and minimum footprint.
The cooling airflow, channeled by the thermostatic controlled axial fan, cools down an oversized combined oil/air heat exchanger: this lets the compressor run in severe temperature conditions.
The ventilation circuit is completed by a cabinet prefiltering panel (standard on every model) that separates the incoming dust and it keeps clean the inside of the machine.
Wide front and rear access panels allow easy maintenance and immediate check of all main components, reducing the time of inspection and maintenance.

DBS 55 - 75 KW

Oil injection rotary screw compressors, with belt transmission and power values from 55 to 75 kW. 

These compressors are extremely efficient thanks to the low rotating speed of the pumping unit and their “Premium Efficiency” IE3 motors.
The machines featuring the ETIV electronic controller can be fitted with the "SMS Device" remote control system for the compressor via the internet.

The range of DARI screw compressors is designed for industrial applications and offered with a different power or technical set-up, depending on the customer’s specific demands.
 All models in the range have the following benefits in common, which are typical of DARI screw technology:

  • High volumetric yield: the free air delivered from our high-efficiency air-ends contributes to lower energy consumption and therefore significant savings.
  • Reliability: the low speed of the air-end guarantees minimal wear and long durability.
  • Optimal monitoring and control: the advanced controllers fitted to the DBS range have been specifically developed to guarantee optimum monitoring and regulation of the operation of the compressor, allowing flexibility and full programming of the complete compressed air station for maximum efficiency and safety.
  • Suitable for intense and non-stop operation: 24hrs without a performance drop.
  • Low installation cost: the versions fitted with tank and dryer are ready for use, with no added cost of installation.
  • Low noise levels: this means the operator can install the compressor near the workstation.
  • Compact design means reduced dimensions
  • Easy maintenance: the DARI rotary screw compressors are built with special attention to facilitate the routine maintenance and accessibility of the internal components.
  • “IE3 Premium Efficiency” motors: combined with our high-performance air-ends, minimize the energy costs. Furthermore, the IE3 motors reduce CO2 emissions: an important contribution to protecting the environment.
