RotaRy BloweR HistoRy The rotary blower evolved from a design of a water wheel invented by the Roots brothers for their woolen mill. The device consisted of two counter-rotating wood-en paddles or impellers inside a casing. Water, guided through the machine, forced the impellers to rotate, turning the shaft and driving the machinery until the wood swelled and the impellers stuck. After it had ...
