The horizontal flow generator (Flo-Gen) aids in cleaning out marinas and narrow canals. Flo-Gen was designed by adopting and simplifying aspects from Flo-Ration, our 3-in-1 aeration system. Unlike its predecessor, the Flo-Gen comes in 2 sizes (3⁄4 HP or 1 HP); both are a single propeller unit strictly dedicated to horizontal flow.
