u-14075A-R

  • Since there is no oil usage it is an environmentally friendly water lubrication compressor suitable for ISO 14000 certification.
  • Direct-coupling, water lubrication, sealing, and cooling are the best in the class and high efficiency achieves lower maintenance work.
  • Inverters for air-cooling fan motors are loaded as well. Capable of showing power Up energy saving and the superior low noise property.
  • “The newly adopted IT touch panel enables smooth operation and control.”
