Models AI4201 Models AI4220

Special design by reinforced resin body and super light weight, only 1.0 kg! Achieves high power (maximum torque 922 N · m).
Small size that can enter even narrow places that did not enter until now. Special design by reinforced resin body.
Achieves high power (maximum torque 700 N · m). Easily to change the setting to be operated with 2 way, either left or right hand.
The setting can be changed so that it can be operated with either left or right hand. The reverse (left) rotation direction is set to a larger output than the positive (right)
Achieves high power with a big hammer mechanism that increases the impact rotation so that loosening work can be performed efficiently.
power at one time despite the small size of the main unit. There is little vibration from twin hammers.
A rotary joint that prevents twisting of the hose. A rotary joint that prevents twisting of the hose.

※ Use a compressor with an air tank. The output of the compressor is recommended to be 0.75 kW (1 PS) or more.
※ If the tightening torque is quite specified, we recommended to use a torque wrench together.
※ 1 The maximum air consumption (ntp) indicates the air consumption converted to the standard condition (0 ° C, 1 atm = 0.1MPa).
The maximum air consumption (op) indicates the air consumption under actual operating conditions (20 ° C, 0.62MPa).
※ 2 Adaptation bolt assumes wheel nut for car.

CAUTION
