Generator Extraction Fan
To soundproof a noisy generator often times an enclosure is built around it. This however causes a build up of heat and if this is allowed the generator will quickly overheat and the motor will burn out. Passive airflow is simply not enough to overcome this problem, you need active airflow that can be managed. The Genesis extraction fan for soundproof generator enclosures is ideal for this application.
The necessary airflow can be created by positioning one fan at the cool air inlet and a 2nd fan on the opposite side at the hot air outlet.
Using a 2 fan setup also offers built in redundancy so that in the event of one fan failing, you still have a backup fan that works.
