Product overview
Ventilation duct increaser galvanised 150-200mm is a stepped round duct fitting used to join two different duct diameters in a ventilation run. It provides a transition from 150mm duct to 200mm duct to suit fans, grilles, or duct changes without reworking the full system. Manufactured from galvanised steel for typical internal ducting environments, it should be joined to compatible round duct components using suitable clamps, screws, or tape. Seal joints where required to reduce air leakage and support the duct run to maintain alignment.
