1. A respiratory pressure therapy (RPT) device for pressurising air to treat a respiratory disorder in a patient, the RPT device comprising:
a water reservoir comprising a water reservoir lid and a water reservoir base pivotably connected to the water reservoir lid, the water reservoir base being configured to retain water for humidification of pressurised air;
a chassis comprising a dock configured to removably receive the water reservoir;
an RPT device inlet configured to receive ambient air;
an RPT device outlet configured to be connected to an air delivery conduit to direct pressurised air to a patient interface worn by the patient during use;
a blower assembly supported within the chassis and comprising:
a first wall portion and a second wall portion;
a blower assembly inlet tube positioned on the first wall portion and configured to receive air from the RPT device inlet;
a plurality of flow tubes positioned on the second wall portion;
a first chamber formed at least partly by the second wall portion;
a second chamber formed at least partly by the second wall portion and opposite the first chamber relative to the second wall portion;
a blower configured to pressurize the air, the blower having a blower inlet exposed to the second chamber and a blower outlet; and
a blower assembly outlet configured to direct pressurized air to the water reservoir; and
an external housing that encloses the blower assembly and at least partially encloses the water reservoir when removably received by the dock.
