Abstract
A ventilation assembly having a moveable trim moveable between an open position in which the moveable trim defines a gap with a ceiling trim to allow movement of fluid and a closed position in which the moveable trim is against or adjacent to the ceiling trim to eliminate or reduce the gap and prevent or limit fluid flow.
Claims20
A ventilation assembly comprising:
- a main housing including an inlet through which air can be received into the main housing and an outlet through which air exits the main housing;
- a blower situated in the main housing and operable to generate a flow of air;
- and
- a trim assembly coupled with the main housing and comprising a moveable trim, the trim assembly being movable between a retracted position in which the moveable trim is adjacent the main housing to limit fluid flow through the main housing inlet and an extended position in which the moveable trim is farther from the main housing than in the retracted position to define a gap allowing air to flow through the main housing inlet;
- wherein the blower is not operable to generate a flow of air when the moveable trim is in the retracted position.

A ventilation assembly comprising:
- a main housing including an inlet through which air can be received into the main housing and an outlet through which air exits the main housing;
- a blower situated in the main housing and operable to generate a flow of air;
- an actuation assembly situated in the main housing;
- and
- a moveable trim movable by the actuation assembly between a retracted position in which the moveable trim is adjacent the main housing and an extended position in which the moveable trim is farther from the main housing than in the retracted position to define a gap permitting fluid flow into the main housing;
- wherein the blower is not operable to generate a flow of air when the moveable trim is in the retracted position.

A ventilation assembly configured to be installed in a ceiling of a structure, the ventilation assembly comprising:
- a main housing including an inlet through which air can be received into the main housing and an outlet through which air exits the main housing;
- a blower situated in the main housing and operable to generate a flow of air;
- an actuation assembly situated in the main housing;
- a ceiling trim configured to be located in an aperture in the ceiling;
- and
- a moveable trim movable by the actuation assembly between
- a retracted position in which the moveable trim is adjacent to the ceiling trim to limit fluid flow through the ceiling aperture, and
- an extended position in which the moveable trim is spaced farther from the main housing than in the retracted position to define a gap allowing fluid to flow through the ceiling aperture;
- wherein the blower is not operable to generate a flow of air when the moveable trim is in the retracted position.
