A round diffuser throws air in every direction at once: concentric cones break the stream into a radial pattern that mixes quickly and lands gently. Beautiful in exposed-duct interiors and quiet in occupied ceilings, with adjustable cone versions that change the pattern from horizontal to vertical in one motion.

Common questions

When is a round diffuser better than square?

For 360° symmetric coverage under the terminal, exposed spiral-duct ceilings, and wherever the interior reads round. Square faces suit grid ceilings; round faces suit everything else.

What does an adjustable cone change?

Sliding the cone carrier shifts the discharge between horizontal (along the ceiling, for cooling) and vertical (down into the zone, for heating): one motion, no tools.
