The wash bay is made with a diamond tread ramp and a 87″ high wall. The wash bay floor pan directs the dirty water and sludge from the equipment being cleaned to a solids collection tank at the rear of the wash bay. Inside the rear tank, a float switch activates a diaphragm pump which delivers the dirty water into the filtration tanks to start the filtration process. After the water has been through this process, a booster pump delivers the water again to your pressure washer. Through the filtrating system, you can use the same water repeatedly. The filters inside the separator tank can be easily replaced, guaranteeing an adequate filtering barrier.
