    • A vent (15) for venting exhaust gases from a component of a respiratory therapy system is provided, comprising: a substrate (15A) having an inner surface and an outer surface, at least one vent hole (17) extending through the substrate (15A) and having a vent hole circumference, the vent hole (17) comprising an exhaust gas inlet (25) at the inner margin of the substrate (15A) and an exhaust gas outlet (23) at an outer margin of the substrate (15A). The vent hole (17) further comprises a sidewall (17A) extending between the exhaust gas inlet (25) and the exhaust gas outlet (23). The exhaust gas inlet and (25) the exhaust gas outlet (23) have different diameters such that the sidewall of the vent hole (17) is inclined at an angle of inclination between the exhaust gas inlet (25) and the exhaust gas outlet (23). The angle of inclination of the inclined side wall of the vent is non-constant around the vent hole (17) circumference.
