Shut Off Impulse Wrenches
Shut off type torque control impulse wrench with double chamber air motor.
A sensor detects the oil pressure inside the impulse unit during tightening and when the tightening torque reaches the preset torque level, a built-in control valve closes the air supply.

Impulse tools save much of maintenance cost!
While impact tools are designed that the hammers hit the driving shaft by the rotation force,
impulse tools take use of hydraulic force to produce tightening force.
Durability of the driving components of impulse tools is, therefore, much longer than that of
impact tools.
Due to the different mechanism, noise level and vibration caused by impulse tools are significantly
lower than impact tools.
Impulse tools prevent over-tightening to improve fastening quality. Although impulse tools and
impact tools show similar torque curve within the first 0.7 second, the torque of impulse tools
lowers rising pace and stabilized at certain stage to prevent serious damage on fasteners.
