Structural Features:

  • DN = Diesel + Noise-reduced canopy
  • Four-stage oil-free compression
  • Integrated aftercooler
  • Forklift pockets for transport
  • Road-towable axle option available

Working Principle:
Diesel engine drives the compressor element through a belt or direct coupling. Four-stage compression with water-cooled inter-stage cooling delivers oil-free air at up to 16 bar. The DN enclosure reduces noise emission by up to 18 dB(A).

Key Advantages:

  • Class 0 air quality guaranteed
  • DN enclosure enables operation in noise-sensitive areas
  • Extended runtime with large fuel tank
  • Road-towable for site-to-site mobility

Applicable Industries:
Construction, offshore platforms, remote mining sites, paint shops, sandblasting, rental fleets.

Installation Requirements:

  • Flat surface or trailer mounting
  • Minimum 1 m clearance from walls (air intake)
  • Water connection: 20 L/min minimum
  • Exhaust routing away from enclosed spaces

Usage Notes:

  • Change engine oil every 250 hours
  • Inspect air filters every 100 hours
  • Never bypass the DN enclosure for noise reduction
