Oil Injected Screw Air Compressor NXVI Series
(NxVi Series 15-75 kW)

The integrated design of Permanent Magnet Motor and Airend offers the best transmission efficiency.

The vertical design ensures that the lubricating oil on the end face of the permanent magnet motor and the spiral rotor is fully infiltrated and further improves the cooling effect of the lubricating oil.

Compact vertical design with fewer parts, no gears or belt results in reduced maintenance needs.

It boasts VFD starting for smooth operations, precise constant air pressure control, and energy-saving capabilities, all enhanced by its fully enclosed variable frequency drive design, enabling reliable performance even in harsh environments.

Permanent Magnet Motor

• Efficiency of PM motor exceeds super premium (IE4) efficiency class
• Fully enclosed lightweight design
• Energy efficient over a wide speed range
• IP66 protection class rating
• Oil cooled - no cooling airflow required
• Oil-lubricated motor means no (re)greasing and reduced downtime
• Longer service life

Patented Airend

• High precision airend designed at R&D center, Germany.
• 5:6 rotor profile air end with large rotor – low speed design guarantees highest performance, lesser vibrations, and longer service life.
• The lubricating oil is injected in compression chamber in the direction of air which significantly reduces oil resistance in the compression process and maximizes the efficiency.

Energy Saving Service-Friendly Package Design

Each component of the FS Curtis NXVi permanent magnet variable speed drive air compressor is meticulously crafted from design concept to actual application to ensure remarkable efficiency, resulting in higher energy-saving levels. The system and structure layout follows the principles of high reliability, high durability, and low noise. The NXVi series offers a space-saving smaller footprint that is easy to install and service friendly.

• Patented intake valve having high efficiency and energy-saving design reduces pressure loss, turbulence and noise.
• Air filter is made of multilayer nanocomposite material and has higher filtration levels, greater strength, longer service life, and significantly lower suction resistance.
• The separator, minimum pressure valve, and thermostatic valve are integrated, reducing the connections by up to 90%.
• Heavy-duty industrial hose assemblies have hydraulic fittings and can be reused.
• Non-asbestos gaskets with high temperature and pressure resistance are used to protect operators.
• The air inlet is equipped with a front filter screen to effectively prevent dust from entering, ensuring the internal cleaning of the air pressure system and ensuring the reliable operation of the unit.
