SpxFlow Shop Air Compressor Automatic Drain

SPX Flow Automatic Drain Valves for Shop Air Compressors

When moisture accumulates inside a shop air compressor, receiver tank, or inline filter, the consequences reach far beyond a wet air line. Corrosion, tool damage, contaminated finishes, and accelerated equipment wear are all downstream effects of unmanaged condensate. SPX Flow — operating through its renowned Hankison brand — has spent decades engineering solutions that address this problem at the source, making their shop air compressor automatic drain products a trusted choice in professional and industrial environments alike.

A Legacy Built on Clean, Dry Air

Since 1948, users around the world have relied on Hankison to provide innovative and reliable compressed air treatment solutions, making it one of the oldest and most experienced compressed air treatment companies in the world. SPX Flow's Hankison brand has earned a global reputation in the compressed air treatment industry for providing customers with the latest technology and superior results. That depth of experience translates directly into automatic drain valve designs that perform reliably under demanding, real-world shop conditions.

Float-Operated and Timer-Controlled Drain Technology

SPX Flow offers automatic drain valves in two primary operating styles, each suited to different shop setups and condensate loads. Their float-operated internal drain valves — including models such as the 3055807 and 3152270 — are a cornerstone of the lineup. The float-operated automatic drain valve is a universal replacement for most float-type drain valves, automatically operating when liquid accumulates within the compressor system, facilitating the release of condensate and debris from the filter bowl.

For applications where scheduled purging is preferred, SPX Flow's timer-operated drain valves allow regular drainage at pre-determined, user-selectable time intervals, designed for use wherever liquids may accumulate in a compressed air system — with user-selectable open-time and off-time drain intervals to adapt drain times to specific requirements.

Designed for Industrial Reliability

The SPX Flow automatic drain is designed for efficient moisture removal in compressed air systems, engineered to deliver reliable performance in industrial settings, making it an essential component for maintaining the integrity and efficiency of air compression systems. Key design attributes across the SPX Flow drain valve range include:

• Automatic moisture discharge to reduce manual intervention and maintenance time.
• Corrosion-resistant construction that ensures longevity in harsh environments.
• Compact design that facilitates easy installation and space-saving benefits.
• Protection for downstream equipment from water damage and corrosion, significantly reducing the risk of system failures and downtime.

Broad Compatibility Across Compressor Types

SPX Flow-Hankison auto drain valves are designed for the automatic removal of condensate from air compressors, air dryers, and receiver tanks. They are used in air compressors, refrigerated air dryers, and air receivers to ensure proper system functioning and increase equipment useful life — and are self-contained, requiring less maintenance time. Whether you run a rotary screw compressor or a reciprocating shop unit, SPX Flow's drain valve lineup is engineered to fit and function as a direct OEM or drop-in replacement.
