Abstract:
A system including an electrically-driven mixing device for mixing a water or solvent-based coating is provided. The mixing device includes a supply container, a rotary agitator shaft and an agitator disposed within the container and coupled to the agitator shaft to rotate therewith. The agitator mixes a coating contained within the container upon rotation of the agitator shaft. The solvent-based coating creates a flammable vapor environment around the container wherein a source of ignition is capable of igniting flammable vapors in the environment. A drive mechanism includes an electric motor having a rotary output shaft disposed outside of the environment and a mechanical power transmission coupled to the output shaft of the motor and to the agitator shaft of the device to transfer torque from the output shaft to the agitator shaft to mix any coating in the container.
