OLE, equipped with fully directable nozzles, creates a whirling throw pattern expanding horizontally. Thanks to its directable nozzles, the throw pattern of OLE is easy to change after installation, for example if the purpose of the room is changed. The OLE is suitable for both constant and variable airflows, and its high mixing ratio also allows cooled supply air. OLE Z is designed for suspended ceilings with a concealed T-grid.

OLE fits FLO balancing plenum box

One of OLE’s most prominent properties is the patented sideways adjustability that makes installation work remarkably easy. Even if the duct installation places the diffuser off-centre in the ceiling opening, the sideways adjustability allows shifting it exactly into place without moving the ducts. This adjustability ensures an always tidy installation and may save a lot of installation time.
