Why use floor ventilation?
When a roof ventilator extracts air from a vehicle, an adequate supply of replacement air is important. A suitable opening in the vehicle floor can provide an additional route for outdoor air.
Combining floor ventilation with roof extraction can support airflow from the lower part of the vehicle towards the roof. This may help reduce moisture accumulation, condensation and unwanted odours.
The grille does not actively move air. Actual performance depends on the overall ventilation system, wind, pressure differences and temperature conditions.
Suitable roof ventilation combinations
- G&C LeMans and Round roof ventilators operating in extraction mode
- G&C mechanical roof ventilators
- Wind-driven Flettner roof ventilators
- Other suitable vehicle roof extraction systems
Check that the total free ventilation area is sufficient for the intended application. The nominal diameter does not represent the net free airflow area.
