COOLING CFM = 325 to 400 CFM / TON
HEAT PUMP = 350 to 425 CFM / TON
GAS FURNACE = max temp rise CFM
ON AVERAGE = 350 to 375 CFM / TON

means
The Designer has Determined
that His Design
Can Handle a
Static Pressure Loss
of 0.10 inch w.g.
per 100 equivalent ft
of Duct Work
and
NOT THAT THE
DUCTWORK WILL
ONLY HAVE A

Key points
Ductulator

1 psi = 27.708 inch or 2.31 ft w.g.
32 psi = 887 inch or 73.9 ft w.g.
