Grizzly G7979 Rotary Phase Converter 20 HP New

The Grizzly G7979 is a 20 HP rotary phase converter designed to run 3-phase machinery from a single-phase power source. It helps shops use existing power more effectively while delivering full motor power with high electrical efficiency.

Built for cool, quiet operation, this converter features a drip-proof cast-iron casing and supports identical input and output voltages. It can be used with single or multiple loads and may be stacked for higher horsepower requirements when needed.

This model is a practical choice for machine shops, woodworking operations, and other workspaces using 3-phase equipment such as lathes, compressors, and dust collectors. It is especially well suited for users who need reliable 3-phase performance without installing a dedicated 3-phase utility service.
