AirCraft Air Impact Wrench Service Kit – Rotor Blades Only 6pc Set (18) for AT0004 (AT0004-SK09)
At a Glance: 6-piece rotor blade (vane) set for the AirCraft AT0004 air motor—an essential refresh for power, efficiency and smooth rotation.
Rotor blades (also called vanes) are the wear items inside the air motor that create sealing and drive rotation as compressed air flows through the motor. Over time they can chip, wear short, or become sticky—leading to slow spin-up, reduced torque and rough running. The AirCraft AT0004-SK09 rotor blades only kit replaces the vane set (reference 18) with a complete 6-piece pack, helping your AT0004 regain motor compression, smoother response and more consistent performance. It’s one of the quickest, most cost-effective ways to breathe life back into a tired impact wrench.
New rotor blades help the motor seal properly against the cylinder wall, improving efficiency and reducing air wastage. If your tool runs but feels weak, struggles to start, or has inconsistent speed, vanes are a prime suspect.
