I have a three blower ventilation system. Blower 1 and 2 are in parallel. Blower 3 is a booster fan connected in series with the other two. Blower 2 currently has a VFD and I would like to put a VFD on blower 3 to account for changes from blower 2. How will blower 1 be effected if the speed...
Amines are very odorous and need to be removed from air before venting. They are also very sticky, like a warm taffy. Where can I find informatin about removing them from the air stream? Water scrubber system does not work!
I have been told it is more efficient to throttle the air flow in duct work on the suction side of a fan rather than the discharge side. Why is this true? Also if two fans are connected in series by a piece of duct work, how do they effect one another?
