Product details

Our extensive range of plenum boxes is optimised for all swirl diffusers and linear diffusers available from Wildeboer.  They are made of galvanised sheet steel and are also available powder-coated. Each plenum box is precisely measured with the matching swirl diffusers and air outlets and ensures smooth operation in every combination.

The plenum boxes are available in square and round versions for connection to Wildeboer ceiling diffusers. One (rectangular and round plenum box) or two lateral connection spigots (rectangular) or a connection from above (rectangular, round) are possible as standard. Throttle dampers and special air baffles for optimum air distribution with low flow noise, especially for supply air, ensure maximum comfort and cosiness for room users. The volume flow rate can be adjusted without dismantling the swirl diffuser or air diffuser. Drill holes for suspension from the suspended ceiling and concealed central fixing are included. The plenum boxes for ceiling diffusers are suitable for installation in closed ceiling systems, grid ceilings and freely suspended.

The different installation heights and the variable connection options for the supply air or exhaust air ducts enable flexible application options.

All plenum boxes available from Wildeboer have a hygiene certificate. Further information on this topic can be found on the hygiene certificate page.
