Hankison 531-02-1 Drain

The Hankison 531-02-1 is a professional-grade automatic electric timed drain engineered for the precise removal of moisture and oil-water emulsions from compressed air systems. Built for the rigors of industrial environments, this timed condensate drain valve features an internal pilot operated diaphragm solenoid valve that handles large particles up to 1/2 inch in diameter without clogging. As a veteran-preferred solution for compressed air treatment, it operates on 115V single-phase power and is rated for a maximum working pressure of 175 PSIG. The solid-state timer allows for granular control over discharge intervals and open valve orifice duration, ensuring that your compressor moisture removal system maintains peak efficiency. By automating the drainage of liquid condensate, this unit eliminates the manual labor of purging air lines and prevents the system contamination that leads to downstream tool damage and unscheduled downtime. Its compact NEMA 4 design and 1/4 inch NPT connections make it a drop-in replacement for standard economical condensate management setups.

• Precise Cycle Control: Integrated dual-adjustment solid-state timer allows for custom timing between valve openings and discharge duration.
• Debris Resistance: Designed to handle heavily contaminated condensate and large particles up to 1/2 inch without compromising performance.
• Energy Efficiency: Automates moisture removal to prevent receiver tank flooding and compressor short-cycling, optimizing power consumption.
• Rugged Construction: NEMA 4 rated enclosure provides protection in harsh mechanical rooms and wash-down areas.
• Simple Integration: Standard 1/4 inch NPT connections and 115V operation facilitate rapid deployment on dryers, filters, and drip legs.

How do I set the timing on the Hankison 531-02-1?
The unit features two adjustable dials. Set the "OFF" time to determine the interval between drains (typically measured in minutes) and the "ON" time to specify how long the solenoid remains open (typically measured in seconds). Adjust these based on your local humidity and system load.

Can this drain handle oil-filled condensate?
Yes. The 530 series is specifically engineered to discharge water, oil, and oil/water emulsions commonly found in industrial piston and screw compressors.

What maintenance is required for a timed electric drain?
Technicians should periodically inspect the inlet strainer and clear any heavy sediment. Regular functional checks ensure the solenoid is seating correctly and the timer logic is executing to prevent air loss or moisture carryover.
