Oil Free Silent Air Compressor

High technology industries demand higher quality
air.To meet the exacting standards of industry,AirHorse
company has developed an outstanding range of DWT
series oil free screw air compressor.The oil free screw air
compressors are not only oil-free,but also oil=less as they
contain no oil at all.Built with the care and attention to
detail that sets all Dwt series oil free screw air compressors
apart from the competition,all models are factory tested
before shipment.

  • Completely oil free, 100% reliability.There is no lubricant in the air end and the compressed air will never be polluted even the air end breaks down.We promise if the compressed air is polluted in this case, we will bear the expenses caused by the pollution. Dry oil free air end: gear box, cooler need lubricate oil which is separated from the compressing chamber by sealing. The compressedair is easily to be polluted if the sealing is damaged. And also the maintenance cost is very high.
  • Isotherm compression, exhaust temperature 50℃.Purified water is functioned for sealing, lubricating and cooling, the exhaust temperature is ≤50℃. Thus, all spare parts operate at the normal temperature.
  • Design without shaft sealing
    guarantee no oil leakage

    Less vibration and lower noise
    Reasonable structure
    Ideal balanced force.
  • High volumetric efficiency, energy saving
    DWT water injected screw air end volumetric efficiency
    up to 95%, general oil free screw air compressor only
    reach 80%. The DWT compressor air production15%
    more than the general oil free screw air compressor.
