Pneumatic Wrench

Often referred to as nutrunners, pneumatic multipliers generally use a stall type air motor to drive a high ratio gearbox to achieve high output torques. Supplied with a calibration chart and regulator unit this allows the operator to set the air pressure to the target torque the tool is required to reach. The tool will stall or shut off once it has reached this torque.
Supplied with soft start triggers to aid socket and reaction location these tools are non impacting and feautre a handle which is independent of the gearbox rotation for optimum operator safety. These are generally offered in pistol grip style with stated accuracies of +/- 5% with the choice of stall or shut off versions.

Standard reaction arms are supplied with every tool with a variety of alternative reaction arms or nose extensions available to suit different applications. When necessary these can be made to order.
Available with single air motor design or twin air motor options with fast rundown and slower torque motors running simultaneously to suit a large range of customer requirements.

Atlas Copco Pneumatic Multipliers
Available in several versions which are “stall”, “shut off” or “Multitorque”.
Stall type offers greater operator choice over the desired torque setting and the tool continue tightening until it stalls or the operator releases the trigger.
Shut off features a shut off valve to control the predetermined torque at which point the tool shuts off the air supply.
Multitorque has up to four preset torque available to the operator which are selected by turning the rotary knob on the rear of the tool which is ideal for multistage tightenings.
