Atlas ErgoPulse系列气动油压脉冲扳手是定扭扳手，可以根据需要设定扭力值，精度比离合器扳手稍低，大概为10%；但此款工具最明显的优点是没有反作用力，无需配置反作用力臂，工人可单手操作；有枪式和直柄型两种型式；扭力范围为2-900NM；可以分为自动断气式和非自动断气式；也可以选择带正反转或不带反转的工具；调节扭力大小简洁方便，只要用随工具配送的手动起子在枪头部分逆时针或顺时针方向旋转螺丝即可；工具在使用过程当中要多注意维护保养，尽量在工具使用前在压缩空气里滴入润滑油，根据具体的使用操作频率制定相应的定期维护保养计划。

其具体特点如下：

EP PTX models
In ErgoPulse shut-off tools the air supply is shut off as soon as the pre-set torque has been reached, minimizing operator infl uence. The result is increased accuracy and faster tightening.
-High reliability.
-Consistent torque over time, low meanshift.
-High level of durability.
-High speed, short cycle times.
-One-handed operation.
-High power-to-weight ratio.
-No springs to wear out.
-No wear on key parts.
-High precision components.
-No reaction forces.
-Light, well-balanced tools.
-Low noise levels.
-Lubrication free.

EP PTS models
ErgoPulse PTS is the reliable and powerful workhorse and offers the same shut-off mechanism as the peak performer PTX. The PTS series has some air on top HRF models, making it possible to feed the air from above to the tool to make it easier to use in many applications. All PTS models can also be used as lubrication free, just like other ErgoPulse tools.
