Power Drawbar Electric or Air | The HobbyMachinist
· FWIW, Grizzly says their pneumatic power drawbar (PD) puts out 135 ft/lbs with 90 psi air and their 220 volt electric PD puts out 240 ft/lbs. The manual for the pnuematic PD shows a torque adjustment, the electric one does not. On the other hand, Maxi Torque Rite says their pneumatic PD "can deliver 40 to 50 footlbs of torque, not 15 to 25 foot lbs like the competition."
