ABSTRACT:
An improved airless blast cleaning wheel and housing. The improved cleaning wheel utilizes axially loaded blade holding slots which, through centrifugal force, as the wheel is rotated secure replaceable impeller blades without the use of spring retainers and the like. An improved housing employs a removable front access plate for gaining access to the wheel and related components and incorporates primary and secondary seals to protect a direct drive motor mounted on the housing.
