Does anybody have or know where I could get a static pressure drop of a
Rheem coil model # RCBA-3765GG17? I have to replace a botched up duct
system. Asking the local Rheem or Ruud distributor for this info. got me
know where because it is a coil older than 10 years. Plus they are not used
to these type questions because nobody knows how to size duct work properly
around here. Thanks in advance.
email Steve @ Noon-Air. He checks email while on his road trip,
include your ph number & he'll probably call ya.
Or grab your magnehelic and take a reading on each side of the
coil.....factor in a few hundred's for a wet coil and be good to
Since it is NOT a new coil forget the initial static drop & follow
Also, how the coil was installed can add considerable back pressure &
reduce the velocity fps force & therefore the airflow through the coil.
With regard to oil furnaces, the above & below can destroy airflow CFM
even if the rest of the ductwork is sized correctly.
Test the Static pressures & velocity flow rate!
