Use of Spin-ins, scoops and air extractors
Use of Spin-ins, scoops and air extractors
(OP)
I am looking for input on the use of spin-ins, scoops and air extractors in branch take-offs in low pressure ductwork. We don't use them generally, but I see them called for on alot of projects designed by other engineers. My feeling is that they restrict airflow and cause greater friction loss than the use of 45deg branch take-offs and air tites. Any comments?
