Gas passage for use in a pap device

A gas passage for use in a PAP device, the gas passage comprising:

• a passage casing having an air intake extending in a horizontal direction and an air outlet extending in the horizontal direction, configured to encompass and accommodate internal components;
• at least two chambers spaced apart in a vertical direction and configured to provide spaces for gas flow and accumulation, the at least two chambers including a first chamber and a second chamber;
• a blower provided within the first chamber, having an inlet to receive gas and an outlet spaced from the inlet in the vertical direction to allow the gas to flow out;
• and
• at least one ventilation component, configured to communicate with the at least two chambers to allow the gas to flow through the at least one ventilation component,
• wherein, the gas flows from the air intake of the passage casing to the air outlet to form a primary flow path with a height difference,
• wherein an entirety of the air intake is at a different height than the air outlet,
• wherein both an ingress to the at least two chambers and an egress from the at least two chambers are provided within the first chamber.

• at least one ventilation component, configured to communicate with the at least two chambers to allow the gas to flow through the at least one ventilation component;
• wherein, an axial line of the air intake of the passage casing is not parallel to an axial line of the inlet of the blower;
• wherein, the gas flows from the air intake of the passage casing to the air outlet to form a primary flow path with a height difference,
• wherein an entirety of the air intake is at a different height than the air outlet, and

• a blower provided within the first chamber, having an inlet to receive gas and an outlet to allow the gas to flow out, wherein the inlet is configured to communicate with one of the at least two chambers that does not house the blower;
• and
• at least one ventilation component in a passage between the first chamber and the second chamber and having an inlet end for gas entry and an outlet end for gas exit, wherein both ends are at a distance greater than or equal to 3.45 mm from an inner wall of the passage casing;
• wherein, the gas flows from the air intake of the passage casing to the air outlet to form a primary flow path with at least one height difference;
• wherein an intake pipe connectable to the air intake is provided at the air intake, and is configured to communicate an external environment with an interior of the passage casing, wherein an outlet pipe connectable to the air outlet is provided at the air outlet, and is configured to receive pressurized airflow from the outlet of the blower,
• wherein the intake pipe has at least one of the following characteristics:
• a. the intake pipe having a draft angle, and the angle being greater than or equal to 0.1°;
• and
• b. a length of the intake pipe being between 25 mm to 80 mm,
• wherein a center of the air intake and a center of the air outlet are at different heights, and
• wherein both an ingress to the at least two chambers and an egress from the at least two chambers are provided within the first chamber.
