I recently got an air cooler which has a fan speed regulator. Still, the lowest setting gives high airflow.
Can I wire it to a fan regulator to limit the air flow without damaging the cooler's electricals?
I understand that the cooler water pump will also receive less electricity.
Edit: It's a swamp cooler
I believe the fan speed regulator controls voltage output. So I am planning to add additional voltage regulator in board.
Like this, instead of fan in image , it will be cooler
