Featured with dual chamber air motor, FPW series pulse wrenches are designed to generate higher torque and yet reducing vibration,
torque reaction  and  noise  levels.  Combined  with  two  blade  impulsing mechanism,  9-blade  dual  chamber motor  creates  about  50%
higher  power-to-weight ratio  than  our  former  series  of  the  same  physical  size. The reduction  of  vibration  and  torque reaction  helps
reduce operator fatigue and other problems associated with repeated vibration or impact motion
