The RCL-80P radial gearing pneumatic torque multiplier is designed for precision tightening and loosening of all heavy duty bolting applications. These pneumatic multipliers are specially designed for heat plate exchanger applications. The torque multiplier shuts-off when the pre-set torque is achieved. Its non-impacting and operates at a smooth, continuous rotation. The torque tool provides quick and simultaneous tightening of large plate packs.Accuracy better than 5%. All Pneumatic Torque Multipliers should use a high quality air filter regulator. Torque setting is obtained by air pressure. Each Pneumatic Multiplier is supplied air-flow chart.
