The Alkota 518B is a stationary electric cold water pressure washer rated at 5 GPM and 1800 PSI. A 6 HP, 230V, 1-phase motor drives the pump and calls for a 30 amp supply. It measures 35 x 25.5 x 38.5 in (L x W x H) and weighs 520 lbs.
The Wash Bay Series is a stationary cold water washer in a weather-shielding cabinet that keeps the pump and motor controls out of the spray. The 518B is built on a welded frame, and its easy-open cover gives quick access to every component for service.
