{E} 1/2" Optimum Drain 115V 230 PSI

Keep your compressed air system operating efficiently with high-quality replacement air compressor drains from Edmac Compressor Parts. Drains help remove accumulated condensate from air compressors, air receivers, filters, dryers, and other compressed air system components, supporting proper operation and helping manage moisture throughout the system.

As compressed air cools, water vapor condenses into liquid condensate that must be removed from the system. Air compressor drains help discharge accumulated condensate before it can collect within equipment or piping. Over time, drain components can become clogged, damaged, worn, or fail due to contaminants, corrosion, scale buildup, and normal operating conditions. A malfunctioning drain may allow moisture to accumulate within the compressed air system, potentially affecting equipment performance and maintenance requirements.

Edmac offers OEM and replacement air compressor drains for a wide range of rotary screw, reciprocating, and industrial air compressor applications. Find the correct replacement using your compressor model, serial number, drain information, or OEM part number.

An air compressor drain removes condensate that accumulates within compressed air equipment and piping. As air is compressed and cooled, moisture naturally condenses into liquid water. Drains help discharge this condensate from compressors, air receivers, filters, dryers, and other system components, supporting proper operation of the compressed air system.

Drain components are exposed to moisture, contaminants, corrosion, and repeated cycling during operation. Over time, drains may become clogged, leak, stick open, or fail to discharge condensate properly. Replacing a worn or malfunctioning drain helps maintain effective condensate removal and supports reliable system performance.

Common signs that an air compressor drain may require inspection or replacement include excessive condensate buildup, visible leakage, drain blockages, continuous air loss, failure to discharge water, moisture carryover into downstream equipment, or recurring maintenance issues related to condensate accumulation.

Compressed air systems utilize several types of drains depending on the application and equipment design. Common examples include manual drains, timer-controlled automatic drains, float drains, electronic no-loss drains, zero-loss drains, and condensate management devices. Each type is designed to remove condensate while supporting specific operational requirements.

Drain replacement intervals vary based on operating conditions, moisture levels, contaminant exposure, maintenance practices, and equipment design. Regular inspection and testing are recommended as part of a preventive maintenance program. Drains showing signs of leakage, blockage, corrosion, or malfunction should be serviced or replaced according to manufacturer recommendations.

The correct replacement drain can typically be identified using the compressor manufacturer, model number, serial number, drain specifications, connection size, operating pressure requirements, or OEM part number. Selecting the proper replacement helps ensure compatibility and reliable condensate removal.

A manual drain requires an operator to periodically open the drain and discharge accumulated condensate. An automatic drain removes condensate without manual intervention using timers, floats, electronic controls, or demand-based operation. Both perform the same basic function of condensate removal but differ in how the discharge process is controlled.
