High Flow Dispensers fills Auto Scrubbers and other large reservoirs at 8 gallons per minute (30 liters/min.) to reduce fill time over traditional dispensers. The DEMA High Flow dispenser features a 1/4 turn ball valve activation and vacuum breaker for backflow protection. The stainless steel cover provides durability and a large area for product identification. The system needs a 3/4” water supply and a minimum of 7 gpm (26L) at 40 psi (2.8 bar) water flow and pressure to operate properly.
