Manifold Box Adaptor 75mm Blaufast MVHR Semi Rigid Radial Ducting System Heat Recovery Ventilation

An important part of the Blauberg Blaufast range is the extract and intake air manifold boxes, essential for an efficient MVHR heat recovery ventilation system.

One Blaufast RKF adapter is required for every port used for to connect semi rigid to the each intake and extract manifold air distribution box. A length of semi rigid duct can then be run and connected to each room that requires intake or extract air. 

Simply cut your semi rigid duct evenly with a sharp knife, push the rubber air tight sealing rings (if required) over the ducts, push the ducts into the connector and clip in the locking rings.

Please insure that all unused manifold ports are blanked off accordingly.
