ABSTRACT:
An air blower for a spa or the like having an outside enclosure formed by a cover that is fitted tightly onto a base, with a blower-and-motor unit centrally located in the enclosure and air inlet passages extending from the bottom wall of the base along opposite sides thereof upwardly into an air chamber in the cover, to the intake of the blower. An acoustical foam lining is provided for the air intake chamber, and the blower is mounted in a nest of acoustical foam and clamped against an internal platform on the base. Blocks of acoustical foam in the air inlet passages in the base, on opposite sides of a central outlet passage, overlie the inlets through the platform into the air chamber, blocking straight-line paths through the passages and partially covering the wall of the outlet passage.
