In another thread I mentioned that I'd like to wall off my DC/compressor closet to decrease noise level in the shop and we got to discussing the need for return air. I have a related question to which I think I know the answer, but would like to confirm.
If I were to pull the exhaust filter (3 hp Oneida cyclone) from the system and exhausted outside, there would be no reason for return air, correct? A list of concerns exhausting to the outside would raise would include the following.....
- loss of conditioned air from the shop
- noise outside near the exhaust
- some dust tossed into the air outside
Anything else? I don't have gas heat or gas water heater in the shop which eliminates that safety concern. This configuration would not decrease the effectiveness of the DC system, would it?
