ABSTRACT:
An air blower assembly for use with spas having a blower-and-motor unit snugly mounted inside an intake housing using a pair of ring-shaped elastomeric gaskets. An outlet housing having a smaller diameter than the intake housing but larger than the motor portion of the blower-and-motor unit, is telescopically positioned inside the intake housing and around the motor portion of the blower-and-motor unit to doubly enclose the motor portion. A muffler, having a muffler inlet port leading directly to a concave air dam, covers an air inlet port on the intake housing to block a straight-line path to the air inlet port.
