Hankison 532-04-300-1 Drain

This Hankison 532-04-300-1 is a professional-grade 115V timed electric drain engineered for the automatic discharge of condensate from compressed air systems. Built for the rigors of industrial environments, this timed electric condensate drain features a heavy-duty 1/2" NPT inlet and outlet connection, facilitating high-flow removal of water and oil emulsions. The Hankison 530 series design utilizes an internal pilot-operated diaphragm solenoid valve, making it highly resistant to large particles up to 1/2 inch in diameter. With a 300 psi maximum operating pressure and a NEMA 4 rated enclosure, this solenoid drain valve ensures reliable performance in diverse conditions, from 35°F to 280°F. The onboard solid-state timer allows for precise adjustment of drain intervals and discharge durations, optimizing air system efficiency and protecting downstream equipment from moisture-related contamination.

• Maximum Reliability: Internal pilot-operated diaphragm is resistant to large scale and debris up to 1/2 inch, reducing clog-related service calls.
• Precise Control: Adjustable solid-state timer allows technicians to fine-tune discharge frequency and duration based on system moisture load.
• Rugged Construction: Features a NEMA 4 rated design and a wide temperature range (35°F to 280°F) for install versatility in demanding plant environments.
• Simple Integration: Standard 1/2" NPT connections and 115V single-phase power requirement ensure straightforward replacement for existing auto-drains.

How do I adjust the timing on the Hankison 532-04-300-1?
The unit features two adjustable dials on the electronic timer. One controls the interval between valve openings (minutes), and the other controls how long the valve remains open (seconds) to ensure complete condensate removal without wasting compressed air.

Is a strainer required for this specific model?
Yes, this 300 psi model typically comes complete with an integrated strainer to protect the internal valve components from welding slag and pipe scale, though the internal pilot design is inherently debris-resistant.

Can this drain be used on high-pressure systems?
This specific model (532-04-300-1) is rated for a maximum working pressure of 300 psig. For systems exceeding this pressure, a dedicated high-pressure variant from the Hankison 530-HP series should be specified.
