The devices comprises a motor; a fan (15) driven by the motor, and a casing (10) defining a housing (101) for the fan. The housing is connectable through a single inlet and outlet port (11) to a respiratory mask (200), wherein a pressure inside the housing is adjustable according to a rotational speed of the fan such that, in use, an inspiration air flow and an exhalation air flow circulate substantially through the inlet and outlet port and through the fan. A kit comprising such an air impeller device and a respiratory mask is also disclosed. |
