Fiamma Turbo Vent

We also use the Fiamma Turbo vent in a washroom where a larger skylight is required. The Fiamma Turbo Vent consumes less energy than ventilation systems of the past and also runs peacefully quiet. It regulates the ingoing and outgoing air of the fan according to the inner temperature of your vehicle, which can also save up to 50% in electricity usage.
