1/4-Inch Drive Air Ratchet
The SPEEDAIRE 21AA62 is a pneumatic ratchet built for industrial-duty fastening where compressed air is available. Its 1/4-inch square drive and ball-detent retainer suit mechanics and technicians working on light-duty bolts and nuts in automotive, maintenance and assembly settings. The tool weighs 1.1 lb and measures 7 3/4 in overall length with a 3/4 in side-to-centre profile for access in confined areas. It is not intended for high-torque breakaway work or cordless convenience.
Torque and Air Requirements
The single figure that decides fit is the 30 ft-lb fastening torque delivered at 90 psi operating pressure with 16 cfm air consumption through a 1/4 in NPT female inlet. A minimum hose size of 3/8 in and supply pressure between 50 psi and 90 psi are required to reach rated output. If the compressor or hose cannot sustain that flow and pressure, the ratchet will not develop its specified torque.
Sustained Operation Behaviour
Under continuous industrial use the rear exhaust directs air away from the workpiece while the free speed of 200 RPM maintains steady rundown without the torque drop-off common in impact tools. The ball-detent retainer holds sockets securely during extended cycles, and the compact side-to-centre dimension keeps the head engaged in tight clearances where larger ratchets cannot reach. Heat buildup is managed by the constant airflow through the motor housing.

Questions about this item
What does the 30 ft-lb torque rating mean when I am tightening fasteners?
The tool delivers up to 30 ft-lb of fastening torque, so it can handle typical automotive and light industrial bolts without needing a larger impact wrench.
How does the 1/4 in NPT air inlet and 90 psi pressure limit affect my compressor setup?
The ratchet requires a 1/4 in NPT female connection and operates at a maximum of 90 psi, so your hose and regulator must match that thread and pressure rating.
Will the 7 3/4 in overall length and 1.1 lb weight fit in tight engine bays?
At 7 3/4 in long and 1.1 lb, the compact body and rear exhaust allow access in confined spaces while keeping the tool light for extended use.
