T175 ventilation shaft with stainless steel grille

A ventilation well is an excellent solution for ventilation below ground level. This product is used for crawl space ventilation, basement ventilation, supply openings for fireplaces, or air supply to indoor boiler rooms.

The ventilation well is a pre-installation box made of ABS plastic and equipped with a heavy-duty stainless steel 304 grille or a galvanized steel grille. The back of the ventilation well is completely open; this provides optimal freedom for creating the required opening in the facade. The T175 ventilation well is also suitable for integration into pavings.

The stainless steel grille has an air passage of 154cm2, equivalent to the passage of an internally ø140mm pipe.
The galvanized steel grille has an air passage of 205cm2, equivalent to the passage of an internally ø160mm pipe.

The underside of the ventilation well is partially open so that any rainwater remains at the front of the wall. The ventilation well is extra long (435mm) and is also stackable. Each extension offers an additional depth of 29-33cm. For larger height differences, two or more boxes can be stacked, allowing for any desired depth. The grille is fastened in the box with four supplied stainless steel screws.

Optionally, a telescopic wall duct PVC ø160mm is available. This pipe is a minimum of 250mm long and a maximum of 450mm, bridging most wall thicknesses.
