The Manthorpe 5" Core Drill Vent G900 is designed for use when ventilating a gas appliance, but can also be used for general through wall ventilation.
The vent can easily be fitted in both refurbishment and new build situations with the use of a 5" (127mm) diameter core drill.
The kit includes a cowl vent for exterior use, a louvre grille for inside, a 350mm length of pipe duct and an optional anti-draught baffle. This baffle reduces the airflow and also the feel of a draught through the vent.
The external cowl minimises uncomfortable draughts, reduces noise and light from outside the property and acts as a barrier against wind driven rain whilst providing a free area of 100cm² and is available in both brown and terracotta.
The Louvre fits on the internal wall and, similarly to the cowl, reduces draughts, noise and light penetration, while providing a free area of 100cm², it is only available in white.
The G901 large back plate vent covers any masonry damage caused whilst creating the hole for the pipe whether this is with the use of a core drill or by chopping out with a masonry chisel.
