Its been so long since ive done a kitchen exaust system im having a brain fart.
How do you guys do your interlock between exaust and MUA?
Im thinking a current relay to prove exaust is running to energize MUA rather than an air proving switch as I think the air switch would plug up with grease rather quickly.
The only issue with a current relay is that your not acually proving airflow, just that the motor is running, so if you had a blown belt the mua would still energize.
Thanks alot for your input.
