Sure Drain SD11

The Sure Drain SD11 is designed to effectively drain liquids from filters, air receivers, air dryers, separators, aftercoolers, and other compressed air equipment where liquids may accumulate. The Sure-Drain is an excellent replacement for float type drains which have a tendency to stick open when water and oil combine into sludge.

The Sure-Drain’s dual time feature not only makes installation easy, but the drain is useful for a wide range of applications without wasting air. Two lights are used to indicate that power is on and when the valve has open status, simplifying visual check and maintenance. There is no guessing with the Sure-Drain.
