Gardner Denver AED Series Automatic Electric Condensate Drains are designed to ensure that manufacturing processes and products do not become contaminated by ensuring that liquid oil and water condensates are discharged from the compressed air stream. Drain installation is typically a part of a complete Gardner Denver air treatment system.

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.

When pipe scale, contaminants from deliquescent dryers or other large particles present in your condensate keep plugging or holding open your common drain valve, it’s time for the DS4 Motorized Valve Drain from Gardner Denver. This valve is designed to handle all types of contaminants without clogging or sticking open. It consists of a 1/2" full-flow ball valve which will perform one full rotation in 7.5 seconds. Battery backup will provide continued operation in the event of a power failure which is something that is not available on most competitor units.

Condensate enters the drain through one of the two inlet connections. As condensate is collected and the translucent reservoir fills, a stainless steel level switch rises. When the condensate reaches a designated level, the level switch sends a signal to the straight flow posi valve, which in turn opens a full-port drain.
