NSK FX Plus FXP-SU M4 Standard Push Button Airotor – 4 Hole Connection (PA2301)

The NSK FX Plus FXP-SU M4 is an upgraded high-speed pneumatic airotor engineered to meet the demands of modern restorative and operative dentistry. The redesigned turbine cartridge delivers increased smoothness, while a reinforced bur retention system holds the bur securely even under increased torque loads — translating into more confident cutting in dense enamel, ceramics, and existing restorations. With 30 W of output power, rotation between 325,000 and 410,000 rpm, and a quattro water spray that distributes coolant evenly across all four sides of the bur, this airotor delivers superior cutting efficiency with excellent thermal protection of tooth structure. Ceramic bearings 25% harder than steel and half the weight reduce wear dramatically, while the Clean Head System prevents oral fluid suckback to extend cartridge life. The angled stainless steel body provides clear direct visibility of the operating site for confident chairside use.
