Adjustable Multi Cone Jet Diffuser

Multiple cones riding one central carrier give this diffuser a trick no fixed face has: slide the cone carrier and the pattern swings from horizontal (cooling) to vertical (heating), matching the season through the face. One terminal, two discharge modes, zero ceiling work.

Common questions

How does one diffuser serve both cooling and heating?

Cooling wants horizontal discharge along the ceiling; heating wants the jet aimed down into the zone. Sliding the cone carrier flips between the two through the face: the diffuser changes season, not the ceiling.

Is the adjustment accessible without tools?

Yes: the carrier moves from below with a standard rod or hand turn, reachable from floor level on most ceiling heights.
