When line voltage at an installation site is below 208 volts for a Whirlwind pump or Ultra Clean compressor, it is recommended that a boost transformer be installed. They are pre-wired for quick installation. Select your booster based on total horsepower of your Whirlwind pump or Ultra Clean compressor. All dual and triple model Whirlwinds should use individual boosters for each vacuum pump or separate circuits.
