    Product Description

    The G960 Telescopic Underfloor Void Ventilator is designed to provide a clear airflow passage to the void underneath a suspended floor.

    The telescopic feature enables the ventilator to adjust vertically between three and five brick courses.

    The right airflow can be achieved when the ventilator is used with a Manthorpe G930 Airbrick.

    The aperture can also accept a standard clay airbrick, although the airflow is reduced.

    Key Features

    • 6,600mm² airflow
    • Allows ventilation to an underfloor void
    • Allows a 3-5 course stagger
    • Additional depth and cavity span available with extension sleeve
  • Technical

    Fitting Requirements

    The G960 should be fitted in at least two opposing walls to create a through flow of ventilation into an underfloor void. As N.H.B.C recommendations state “Ventilators should be placed at not more than two metre centres and within 450mm of each end of the wall”. Bricklaying should then be completed as normal although care should be taken to keep the air flow passage clear from mortar droppings.
