MaxFlo VS™ is right sized for most medium head applications, which means it pays for itself faster than larger, more expensive variable speed models. Upgraded features such as a new built-in timeclock make operation even easier. The intuitive userinterface is now rotatable so it always faces the right direction and the new wiring compartment makes installation quick and reliable. MaxFlo VS™ is an ideal upgrade for those looking to reduce energy use and save money.
