The 36-3 high-flow, high-efficiency sand media filter is designed for all types of general filtration applications in which sediment removal is the primary goal. The unit filters up to 425 gpm while operating at pressures up to 100 psi. The AC- and DC-powered automatic filter backwash controller allows for both timed pressure differential or manual backwash intervals. It may be used as a stand-alone filtration system for dewatering and can clean water prior to offsite discharge as well. Rain For Rent. www.rainforrent.com.
