Timer Drains are electrically operated units in which an adjustable timer periodically opens a valve to remove accumulated condensate. Timer Drains are basic components used in most compressed air systems because they provide an inexpensive, reliable means of removing condensate without having to manually open drains valves. Timer Drains are used on filters, air receivers, air dryers, separators, aftercoolers, and other compressed air system components. All models are designed with solid-state controls for reliability. Several types of valves and timers are used to fit the customer's specific needs.
