Hi all!
This is my first post here so bear with me. This would be easier if I could attach a pic but I guess I need seven posts before the sight will allow it. I'll do my best to explain.
I'm renting an industrial unit where we just had an RGS090-180 installed on the rooftop. The registers are about 9' up the wall and it seems to me the techs plotted out the locations of those registers a bit prematurely. They ended up accommodating the locations by adding two 90 degree elbows to each round 8" offshoot from the main conduit before transitioning into rectangular boxes for the registers, meaning the airflow changes direction three times in what (to my mind) should have been a straight run terminating with a round 8" register. There are 14 of these offshoots which means the airflow is being redirected 42 times where it could have been 0! I'm just wondering what kind of resistance this creates to the airflow and how much more it will tax the unit.
Thanks!
