VisqueenPRO Gas Vent Box – Stainless Steel

VisqueenPro Gas Vent Box comprises a stainless steel base with a 110mm pipe inlet and adjustable feet for leveling purposes and to secure the box within the concrete surround. The galvanised steel grating lid is 530mm x 123mm and is secured with locking bolts.

Each vent box provides a free air flow capacity of 20148mm².

VisqueenPro Gas Vent Box is a high performance ground level vent box that when installed as part of a Visqueen gas venting system will safely disperse harmful gases to atmosphere and reduce the risk of rainwater entering the void. The product can also be used to ventilate air spaces e.g. the open void below suspended precast concrete floor structures.

The vent box is typically used in applications where the gas dispersal system cannot be taken out through a perimeter masonry wall e.g. curtain walling and glazing systems. The vent box is normally positioned close to the building perimeter wall but is suitable for load class B125 to BS EN 1433:2002 which includes pedestrian precincts, light vehicles and private car parks.
