In-out air function with specific buttons, air intake and exhaust from inside the caravan/caravan/camper
With manual opening
It works at 12 v and has 2 speeds on intake and 3 on exhaust.

Dimensions: 42x42x18 cm (lxwxh)
Mounting/cutting dimensions: 28x28 cm (max 30x30 cm)
It can also be mounted on a 30x30 cm gap, with a little adaptation or by keeping the inner frame of the old hatch/which must be changed
Installation thickness: 3.8-6.5 cm (the inner frame comes with a cover for any ceiling thickness (3.8-6.5 cm) that can be adapted by cutting)
Intake/exhaust air volume of 20-30 cbm/min
1000 revolutions per minute
Can be used while driving, recommended at distances up to 80-90 km/h
Very quiet, does not make noise
In the case of converting a camper/caravan/motorhome, installing two hatches, one in the front and the other in the back (one of them works on the intake and the other on the exhaust air) creates a continuous air recirculation, a fresh and quite cool air flow so that it is no longer necessary to use a portable/mobile air conditioner stationary.
Installation to the electrical system:
A 1.5 mm2 or thicker cable is used
The red cable connects to the positive terminal of the battery
The black cable connects to the negative terminal of the battery
