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.
