Zero-loss condensate drains. The last drain you'll ever have to buy.

Timer-style condensate drains waste compressed air every time they open, which adds up to real money, on average $800 to $1,000 a year per drain in lost air. Drain-All drains are fully pneumatic and zero-loss: they discharge condensate without releasing a single CFM of the air you paid to compress. No electricity means they install anywhere along the system without running power, and the patented magnetic control circuit has few moving parts compared to float-style drains that stick and fail. The Handler product line covers nearly any condition: the Condensate Handler is the industry standard, the Rust Handler passes rust particles without plugging or sticking open, and specialized models handle oil, high pressure, temperature extremes, vacuum and high volume. Backed by a 3-year warranty and made in the USA by Control Devices. These aren't the cheapest drains on the market. They're the last ones you'll buy.
