Re: Blow air in or out? shop ventilation
Dean, your first diagram is a classic illustration of a poorly designed system. I saw this all the time on indoor generator set installations.
By locating the air intake and discharge so close to one another, the air flow is ďshort circuitedĒ.
With air intake and discharge located properly on opposite sides of the room, preferably air-in down low and air-out up high, drawing air out is far better than blowing air in.
