Flettner 2000 ™ adapter
If you are mounting a Flettner 2000 ™ fan on a vehicle with a plywood or other substantial material covering more than 9 mm thick, you must use a Flettner 2000 ™ adapter. The adapter is designed to bridge a gap of up to 50 mm (1.97 inch) between the inner liner and the outside of the vehicle. The Flettner 2000 adapter is made of high-quality ABS plastic and can be adjusted to the required size.
