VIFIDI Bullet VFD is an all-in-one and in-line pump inverter to upgrade and manage most newly installed and existing water pumps. Like most pump inverters, it can provide constant water pressure and save energy based on water consumption. Bullet VFD delivers simplicity and efficiency by consolidating all functions in one device. Besides, by providing an intuitive interface, even non-professionals can easily read and operate it. This new design integrates all necessary functions and components of a conventional inverter booster pump and is highly adaptable for most existing systems. As a result, it can save time, money, and space.
