Powerheads are more direct, making pressurized air uses more energy than any
other type of power. One of those things I learned while working for DuPont.
Air power is more versatile to use than direct power but more expensive in
energy used to make than any other energy source. Powerheads turn electricity
directly into suction but air pumps must use electricity to make pressurized air
then the air is used to make suction, Just not as efficient but pressurized air
is more convenient. Which is more important?
