Conversely, the return must go as near to the center from the system as you possibly can, in an open spot not exposed to excessive humidity or grease.
On the much stop of the principle duct the air is divided into two branches by way of a gentle, curved tee section. This permits the air to efficiently transform course and therefore there is absolutely no sudden boost in static force plus the air stream level into the rooms has considerably greater.
Did you see that we claimed ductwork is sealed with aluminum tape? Regardless of the deceptive title, duct tape isn’t suitable for sealing ducts.
