I have a 220V spa blower that is too strong, bubbles blow above the top of the spa..I know I can buy a smaller blower but wondering what would happen is I ran it on 110V vs 220V. Would it run slower?
Blower motors are cooled by air flowing over the motor. The
amount of air required to prevent overheating is determined by
the blower horsepower (HP), the system back pressure and the
number and size of the air holes/jets in the spa. Airflow is meas-
ured in cubic feet per minute (CFM).
Different horsepower blowers require different levels of air flow
to keep the motor cool. A higher HP motor requires more flow.
System back pressure, measured in inches of water, is the sum
of the forces restricting air flow over the blower motor and
through the spa plumbing. These limiting forces include:
• Pipe diameter • Number and type of elbows
• Length of run • Check valves
• Number of spa jets • Size of spa jets
As back pressure increases, air flow decreases, reducing the
ability of the motor to stay within normal operating temperatures.
