An industry first! You'll only find it at Sunlight Supply! E.Sybox by DAB solves the problem of maintaining consistent, constant water pressure in your hydro pump system across several rooms and installations, from a distance or to an elevated area. The E.Sybox is a compact booster pump that's about 30% smaller than traditional pump and controller systems. At 45dB (decibels) it's whisper quiet. E.Sybox only uses the power necessary to provide the pressure and flow needed making it highly energy-efficient and E.Sybox can be mounted horizontally or vertically depending on your needs/space requirements. If multiple E.Sybox units are in use, an integrated wireless communication system allows the units to communicate with the other pumps for easy monitoring. Now available in a smaller size.
