Abstract: An air handling unit includes a rain hood configured to receive an air flow from an external environment surrounding the rain hood, and a sensor disposed within the rain hood and configured to monitor air flow parameters indicative of a flow rate of the air flow.

Abstract: A damper system includes a damper housing configured to flow air, a damper blade disposed in the damper housing and having an orifice, the damper blade being rotatable in the damper housing between a closed position and an open position. The orifice is configured to allow air to flow through the damper blade while the damper blade is in the closed position. An auto-balancing damper is disposed in the damper housing apart from the damper blade, and the auto-balancing damper is configured to regulate a flow of the air through the damper housing.

Abstract: A damper (e.g., a safety damper) includes a sensor configured to provide a damper blade position signal indicative of a position of one or more damper blades and a communication interface configured to provide a damper identification and a damper blade position information associated with the damper blade position signal at periodic intervals or in response to a change in position. The damper identification and damper position information can be provided to fire safety equipment, another damper, or a safety panel.

Abstract: A frame assembly for an air distribution system includes a damper assembly, a louver assembly, and a screen frame. Air flows through the damper assembly and the louver assembly, where the damper assembly terminates in a first flange and the louver terminates in a second flange. The first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.
