HSC D Series – Direct Driven Rotary Screw Air compressors

  • Capacity : 4 – 53m3/min
  • Pressure Range: 7-13 Bar

Delivers high performance, reliability and durability. Directly coupled drive system. Oil injected rotary screw compressor. Responds to all requirements between 22 kW and 315 kW. For special requirements please call us….


HERTZ HSC D series compressors deliver high performance by reducing the power transfer losses with their directly-coupled motor and screw block. Operation expenses are reduced thanks to usage of the latest generation screw block and motor. Stops are minimized with continuously supplied air.


Hertz Kompressoren rotary screw compressors are equipped with easy-to-use, robust and long-lasting microprocessor controllers with communication capabilities as per the product line to ensure smooth operation and uninterrupted production


  • Patented and durable screw block that provides high-capacity of air,and that is specially selected for each model’s capacity requirement
  • Production of air with high volumetric efficiency, thanks to the new rotor profiles, and lower torque requirements
  • New generation bearing design with increased load carrying capabilities


Spin-on or immersed type separator design depending on the product line

Immersed type separator

  • High performance separation with three-stage design
  • More efficient separation at lower volume with deeply wrapped,intertwined separation layers
  • Low amount of oil mist in outlet air ≤ 3 ppm

Spin-on separator

  • Easy replacement, ease of assembly and disassembly
  • Design that does not require a separator tank


  • High efficiency 400V/3 phase/50Hz, IE3 IP55 electric
  • motors with F Class insulation
  • Direct coupled model, long-lasting and efficient transfer system thanks to use of elastic couplings
