Peter,
Think of it as an Ohm's Law problem, with parallel resistors. If you have one
resistor and a certain requirement for current flow through it at a specified
voltage, when you add a second parallel resistor the total current required
from the power supply is doubled. CFM is the amperage, back pressure is the
voltage. You need twice the CFM at the same back pressure.
