The VQA-RH is a hexagonal displacement device intended for floor mounting.


The inventive and modern low velocity diffuser’s flow can be adjusted individually with its round equalising nozzles. The perforated front (normally long-hole perforation) is undetectably attached to a plenum unit with either round or rectangular spigot. With ease, the device can be removed for cleaning purposes or adjusted. Following on with its subtle design, there are no visible screws or other fastening systems.
