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

Description

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.

Directions for Use

Setup

• Connect the airotor to a Midwest 4-hole coupling on the dental unit
• Verify the air and water supply pressures meet NSK’s recommended operating range
• Run the airotor briefly without a bur to confirm smooth rotation and confirm all four water spray jets are functioning

Bur Insertion

• Press the push button on the head of the handpiece to release the chuck
• Insert the appropriate FG (Friction Grip) bur fully into the chuck
• Release the button to lock the bur securely in place
• Gently pull the bur to confirm the reinforced retention system has engaged before clinical use

Clinical Operation

• Activate the foot pedal to begin rotation and verify quattro water spray is reaching the cutting site from all sides
• Apply the bur to the tooth surface using light intermittent pressure for optimal cutting efficiency
• Take advantage of the increased torque capacity for confident cutting through dense enamel or ceramic restorations
• Pause periodically to assess cutting progress and prevent overheating

Cartridge Replacement (When Needed)

• When cartridge performance declines after extended use, the cartridge can be replaced in-practice without sending the handpiece for service
• Follow the NSK cartridge replacement procedure to swap in a new FX Plus cartridge
• The replacement cartridge includes integrated spray holes ensuring water spray performance is restored

Post Use Care

• Run the airotor briefly with water spray to flush debris before disconnecting
• Wipe the external surfaces with the recommended surface disinfectant
• Lubricate the handpiece using NSK-recommended cleaning and lubrication products before sterilization
• Autoclave the airotor as per NSK’s sterilization protocol
• Store on the dental unit holder or in a protected case when not in use
