A firestat for providing an output for controlling an opening and closing of a fire/smoke damper. The firestat includes a fire/smoke damper test switch and an actuator configured to depress the fire/smoke damper test switch. The firestat is further configured to release the fire/smoke damper test switch in response to a depressing force applied to the actuator, wherein melting or other damage to the actuator causes a release of the test switch.

An air purifier includes: a case in which an inlet is formed at a lower portion thereof and a discharge port opened in a horizontal direction is formed at an upper portion thereof; a purifying unit accommodated inside the case; and air-blowing unit for sucking air into the inlet and allowing the air to pass through the purifying unit, and then blowing the air to the discharge port; an air current control body in which an opening portion that is less in size than the discharge port and opened in the horizontal direction is formed; a lifting instrument for lifting the air current control body; and a rotation instrument for rotating the air current control body.

A vehicle register assembly includes a register duct that has an end opening and the register duct directs air. A housing is coupled to the register duct proximate the end opening. A barrel is disposed within the housing and defines an upstream aperture and a downstream aperture. A plurality of vanes includes individual vanes and the individual vanes extend in a first direction between first opposing sides of the barrel. A linking vane is coupled to each of the individual vanes and extends between second opposing sides of the barrel. The linking vane includes a guide body that extends upstream from the plurality of vanes.

A blow-out unit disposed at a blow-out port on an air flow path and configured to blow out air supplied through the air flow path, toward the room, includes: a first member disposed in the blow-out port and including a plate member having a first side and configured to turn around a rotating shaft disposed away from the first side such that the first side moves away from the blow-out port toward the air flow path; and a second member disposed in the blow-out port at a different position from the plate member and extending along the first side of the plate member. The plate member and the second member change a direction of air to be blown out toward the blow-out port through the air flow path from a first air flow direction to a second air flow direction.
