Unit is a 90%, 39.6k output, 814CFM. Works out perfect for the 2 ton AC also. The 150W is a SINGLE SPEED 825RPM PSC condenser motor. 3 speed PSC motors have a lot of "winding waste" for the lower speeds that makes a big impact on efficiency.
The fun part is the motor is the 1/3HP 230V motor running on 120v. Couldn't find a 825 RPM 115v motor anyhwere, thought I'd try a 230v and modify the cap. The motor specs a 7.5UF cap, had to use a 10UF to get to to run properly on 115v. Tried a 12.5uf, but it increased amp draw without any change in speed. Motor is rated for 1.8A @ 230v, draws 1.2A @ 120v. Power tests were done with a Kill-a-watt.
Blower wheel is 10x8, original motor 1/3HP 115v 4 speed. "3 ton drive" if you will. Ductwork is all flex, (2)12" returns with 20x20x4 filters. (2)10" plus (2)8" supply ducts off of the main 17"x20" plenum. Ductwork is a bit oversized for 800CFM, old system was 3 ton/88k @ 1200CFM.
