Question

I'm planning to install heki rooflights - 1 Mini Plus and 1 AirQuad - in a van conversion. What is the difference between the 2 ventilation options?

Answer

The Air Quad has a patented air flow guide which allows much better control of the amount of air entering the vehicle. This is done partly by the fact that the raised height of the dome can be adjusted and it has a dome designed to direct air into the vehicle. The Mini Heki Plus. although having 5 opening positions, only one of these positions is where the dome is parallel to the roof, the other positions being at an angle and control of air flow is more difficult and arbitrary.
