Chicago Pneumatic 8941078308 1/2 in Air Ratchet 10-90 Ft-lb

Product Description

The CHICAGO PNEUMATIC 8941078308 is a pneumatic air ratchet built for professional mechanics, automotive technicians, and industrial service crews who need controlled torque in tight spaces. Driven by compressed air at 90 psi, it delivers a torque range of 10 to 90 ft-lb through a 1/2 inch square drive. The inline handle design keeps the tool low-profile and easy to maneuver in confined engine bays or undercarriage work. At 3.5 pounds and 12 inches in overall length, it balances reach with manageable weight during extended use. Air consumption is 5 CFM, making it compatible with standard shop compressor setups.

This air ratchet is suited for general automotive repair, fleet maintenance, and light industrial assembly where consistent pneumatic torque output is needed. The 1/4 inch NPTF inlet is a standard connection found on most shop air lines. Side exhaust directs spent air away from the work surface and the operator. It is a single-operator hand tool intended for use with a compressed air supply in professional shop environments.

• Torque range of 10 to 90 ft-lb (13 to 122 N/m) covers most automotive and light industrial fastening tasks
• Inline handle keeps tool profile low for access in confined spaces
• Side exhaust location directs air away from the work area
• 190 RPM free speed for controlled, efficient ratcheting

Compatibility

Designed as a standard 1/2 inch drive pneumatic air ratchet compatible with shop air systems operating at 90 psi and supplying a minimum of 5 CFM through a 1/4 inch NPT air line connection.

Installation Notes

Installation and operation should be performed by a qualified mechanic or pneumatic tool technician. Before connecting to an air supply, verify the shop line pressure does not exceed the rated 90 psi operating pressure and that the air supply delivers at least 5 CFM. Use a properly sized 1/4 inch NPTF fitting and inline oiler to maintain tool longevity. Disconnect the air supply before changing sockets or performing any service on the tool.
