G900 - 5 Inch Core Drill Ventilator

by Manthorpe Building Products Ltd

The 5' Core Drill Vent G900 is designed for use when ventilating a gas appliance, but can also be used for general through wall ventilation. Available with a large backplate to hide remedial works.


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.


Key Features

100cm² of airflow without draught baffle

70cm² effective airflow with baffle

Fitting Requirements

Screw the backplates into the outer wall and inner plasterboard. Align and clip the cowl and louvre grille over the backplates.
