An air flow producer of non-rectangular shape is adapted for installation in a rectangular opening of a drop ceiling. In preferred form, the producer has a circular housing with an open bottom covered with a grill. A fan with a rotary blade assembly is mounted in the housing to produce a downward air flow, and a circular metal band surrounding the rotary blade assembly defines an air discharge zone centered in the grill and an annular air intake zone surrounding the discharge zone. Flow rates are optimized by positioning the band close to the grill. The grill is preferably integrally molded with a rectangular flange that seats in the drop ceiling opening. The flange supports the housing from the framework and closes the opening to prevent the producer from drawing air from the plenum above the drop ceiling.

A horizontally extending suspended ceiling segment that appears to float in space. Support hangers in an upper tier connect to a grid that forms a lower tier, and cantilever the outward ends of the beams in the lower tier. A perimeter trim strip surrounds the suspended ceiling segment, on the outward ends of the beams in the grid. The support hangers, and hanger wires that support the suspended ceiling segment, are hidden behind the line of sight of a viewer positioned below the segment.

An adapter bracket which enables the installation of a door frame or louver into a recessed fixture that sits on a T-bar supported by a ceiling without having to custom design a hinge and latch system to match the original fixture or require the installation of a false frame that lifts the fixture. The brackets slide between the T-bar and the existing fixture. The bracket is also slightly wider than the T-bar opening. The door frame will keep the brackets spaced wide enough to ensure that the assembly would not fall out of the opening. The hinge and latch mechanism for the door frame is built into its end rails and latches onto the bracket to ensure the door frame is supported and held in position.
