Why choose a Master Water Lubricated Oil Free Rotary Screw Air Compressor?

  • Utilizes Japanese high-efficiency air end technology and a variable frequency drive which features a soft start, for optimal energy use, leading to cost savings and reduced carbon footprint. 
  • Permanent magnet heavy-duty IP 55 motor.
  • Innovative oil-free screw design, low-temperature compression, and low RPM operation for extended lifespan and reduced maintenance. 
  • Offers high efficiency and low operational costs through water lubrication single-stage compression, and minimizes maintenance expenses. 
  • Fully accessible sound-attenuated corrosion-proof enclosure. Constructed with stainless steel 304 and special alloy materials, processed by CNC machining for rust-free, reliable operation. 
  • Pure copper radiator with stronger heat dissipation than aluminum counterparts, 5-10 years longer service life than other suppliers. 
  • Advanced design and water lubrication provide enhanced compression, ensuring a consistent reliable air supply. 
  • 304 Stainless steel liquid-cooled heat exchanger, minimum pressure valve, intake valve, etc. 
  • Water-lubricated, single-stage compression guarantees oil-free operation, ideal for critical air quality applications. 
  • User-friendly Full-colour High-end LED touchscreen controller, low maintenance and extended durability to ensure a seamless ownership experience (pre-programmed plug & play system). 
  • Direct drive results in low maintenance and high efficiency by eliminating any power transmission losses due to belts and pulleys.

    Lubrication method  

    Impurities in the air and circulating water are filtered through a water filtration system  

    Both gearboxes are lubricated with oil.   

    (high temperature and high speed)  

    Noise  

    ≥ 10 dB less than dry compressors.  
    (Low motor speed means less noise)  
      

    Higher dB.  
    (High motor speed means more noise)  

    Maintenance Cost  

    Relatively simple structure, low maintenance cost  

    The structure is relatively complex, and the maintenance cost is high

    Water Lubricated Oil-Free Compressors offer more than 15% energy savings compared to Dry Oil-Free Compressors!
