I have my DC piped all through my shop. It's been running great since I installed it about 12 years ago. The outlet side of the blower unit is an 8" round. I used to have it hooked up to a large truck air filter to put that air back in the shop. Since I can't afford to keep replacing those air filters any longer, I'm wanting to vent it to the outside of my shop. What are your ideas to run and vent that 8" outlet outside my metal building shop? I don't want to leave it open for birds, bees, wasps, and etc....oh to include rain....so I'd like to have something I could close manually or a DIY that would close itself when the DC air flow stopped.
Thoughts, ideas, suggestions?
