OG exemplary drawing
 
1. A flow generator for generating a flow of pressurized breathable air to be delivered to a patient for respiratory therapy, the flow generator comprising:
a housing forming an interior;
a blower supported within the interior of the housing and configured to generate the flow of pressurized breathable air,
wherein the blower includes a blower inlet and a blower outlet;
a pair of plates provided to the housing and arranged upstream of the blower inlet of the blower,
wherein the pair of plates are arranged in parallel,
wherein each of the pair of plates includes a plurality of apertures,
wherein the pair of plates and the plurality of apertures are configured and arranged to form a plurality of inlet passages to direct incoming air flow to the blower inlet of the blower, and
wherein the plurality of inlet passages are arranged in parallel;
an outlet tube arranged downstream of the blower outlet of the blower,
wherein the outlet tube comprises a tubular side wall,
wherein the tubular side wall includes an inlet end and an outlet end,
wherein the tubular side wall includes an axis that is parallel to a longitudinal axis of each of the plurality of inlet passages, and
wherein the outlet end of the tubular side wall is arranged outside the interior of the housing and configured to directly connect to an air delivery tube for delivery of the flow of pressurized breathable air to a patient interface; and
a suspension device configured to at least in part support the blower within the interior of the housing,
wherein the suspension device comprises an elastomeric material,
wherein the suspension device comprises an elastomeric, tubular seal member configured and arranged to provide a seal between the inlet end of the tubular side wall and the blower outlet of the blower, and
wherein the elastomeric, tubular seal member includes an axis that is coaxial to the axis of the tubular side wall.
