AirVent family →The drum louver is the wide-throw workhorse: a cylindrical face of parallel vanes that discharges a broad band of air rather than a single cone, covering a whole seating block or production line from one terminal. Aim it in its housing, lock it, and it holds for years.

Depending on size and duty, in the 10–25 m class: aimed and locked at commissioning. The spherical seat holds aim through years of vibration, unlike grilles whose settings wander.
Machine halls, forge and foundry lines, welding bays: anywhere whole-hall air conditioning is uneconomic and comfort has to reach the workstation, not the roof.

Spot jet nozzles in trim rings: aim a column of air exactly where a person sits, theatre seats and workstation islands included.
Stacked cones on a single carrier: shift the whole discharge pattern from horizontal to vertical without touching the ceiling.
