Dometic Mushroom Vent for Roofs

This adjustable grey mushroom vent can be fitted to most steel or glass-fibre roofs and ensures adequate, adjustable ventilation without the need to leave windows open.

This vent is designed for a roof 25-45mm thick. If your roof is thinner, parts of the vent can be shortened. Aperture needs to be 130mm External diameter is 190mm

The Dome airflow is as follows: (note this fan is NOT electric) - 3-12m3/h with the fan off and at wind speed of 1-4m/s - 65m3/h with the fan speed set to half - 105m3/h with the fan speed set to full

To allow the vent to close and open a small circlip has to be removed from the centre, by first removing the three screws holding the dome in place
