Auto Drain Valve for Compressed Air Systems
The SPEEDAIRE 53DN44 automatically removes condensate from compressed air lines using a timed electric solenoid. It handles a drain rate of 4.0 gpm and connects via a 1/4 in drain port with a 1/2 in NPT pipe inlet. The unit operates on 115 V AC at 60 Hz drawing 0.3 A and includes a 6 ft grounded power cord for direct connection.
Adjustable Cycle Limits and Pressure Range
The valve offers an adjustable drain cycle between 0.5 min and 45 min with a purge duration from 1 sec to 10 sec. Maximum operating pressure is rated at 300 psi. The brass body is housed in a NEMA 4 enclosure rated for an operating temperature range of 35 to 165 Degrees F, protecting internal components from dust and water ingress.
Replaces Manual Drain Valves on Air Compressors
This unit upgrades manual ball or petcock drains that require operator attention and often remain open, wasting compressed air. The timed automation suits installations where condensate accumulates steadily and regular purging prevents corrosion or water carry-over. It is not suited for systems needing zero-air-loss demand drains or for pipe sizes larger than 1/2 in NPT.

Questions about this item
How do I choose between the adjustable drain cycle and purge time settings?
The drain cycle adjusts from .5 to 45 minutes and the purge time from 1 to 10 seconds, so you set the cycle for how often to drain and the purge for how long each drain lasts.
What does the 4.0 gpm drain rate mean when the valve is installed on a compressor?
It means the valve can discharge up to 4.0 gallons of condensate per minute through the 1/4 inch drain port when operating at system pressure.
What does the NEMA 4 enclosure rating cap in terms of environment and voltage?
NEMA 4 protects against splashing water and hose-directed water, and the unit runs on 115 V AC at 60 Hz drawing .3 A.
