摘要： A blower has a blower housing of clamshell construction, including two housing members having a scroll back wall molded with radial draft, an impeller and a motor within the housing, and a static tap connected to the housing. The impeller has a backplate with a backplate back surface region of substantially the same radially converging shape as that of a front surface region of the scroll back wall formed by the radial draft, providing a substantially uniform axial gap between the backplate back surface region and the scroll back wall. The impeller has a ring connected by a skirt to the back plate to define a stepped area behind the ring. The impeller includes impeller blades extending forwardly from the impeller backplate and the ring and back fins extending rearwardly from the ring. The blower has a scroll width of about twice an impeller exhaust width.

摘要： A system for use with a spa adapted for use with a pump having a drive hub. The system comprises an adapter and a disposable pump. The adapter: has a housing defining a recess, a rotor in the recess and an operative position; and is adapted, when operatively positioned: for rotation of the rotor upon rotation of the drive hub. The disposable pump has: a housing having a pair of sides and a void, one of the sides defining an intake and a port, the intake communicating with a center of the void and the port communicating with a void periphery; an impeller in the void; and an operative position adjacent the adapter. The disposable pump is adapted, when operatively positioned, for rotation upon rotation of the drive hub and consequent rotation of the rotor, to draw water through the intake and eject water through the one or more ports.
