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
