Gardner Denver's DS3 Series Electronic Timed drains are ideal for small or large condensate loads. The DS3 Series consists of two products — the mini and the general. The Mini is ideal for smaller filters. The General is better suited for larger filters, refrigerated dryers, receiver tanks, and other general purpose applications. Both drain valves feature state of the art electronic timers and brass valve bodies, which come standard. The general model is available in corrosion free stainless steel and high pressure. The DS3 can also incorporate the optional Gardner Denver "4-Port" controller which automatically controls four independent solenoid drains due to the need to have electric timed drain valves operating at various intervals.
