McQuay LSL128DH Serial 3TM00552-04
Any suggestions on reducing the output cfms on this air handler?
Store is being split into two seperate locations and the system will be close to halved.
Looking for a 30-50% reduction. Not sure of all the details yet but thought I would start asking now.
What other info might you need?Some people know the cost of everything but the value of nothing.

I you don't have it, here is the Installation and Maintenance Data Manual for this unit. Maybe you can find something in it to help.
Instead of learning the tricks of the trade, learn the trade.

Change the RPM. RPM is directly related with CFM. Need 50% less CFM, slow the RPM 50%.
