ELGi Auto Drain Valve for Air Dryers & Air Compressors

Ensure efficient condensate removal from air compressors and air dryers with ELGi Auto Drain Valves engineered as efficient drains to protect your compressed air system while maximising energy efficiency.

Efficient condensate removal is critical to maintaining compressed air quality, protecting equipment, and reducing energy loss. ELGi Auto Drain Valves are engineered to automatically discharge condensate from compressed air systems without releasing compressed air—ensuring reliable performance, system protection, and measurable energy savings.

Designed as part of ELGi’s complete compressed air system, these drain valves are suitable for use with air compressors, refrigerated air dryers, aftercoolers, air receivers, moisture separators, and filters.

Why Condensate Drainage Matters

During compression and cooling, moisture in atmospheric air condenses and accumulates within compressed air systems. If not removed effectively, this condensate can:

  • Corrode pipelines and air receivers
  • Damage pneumatic tools and downstream equipment
  • Reduce process efficiency and air quality
  • Increase maintenance costs and unplanned downtime

ELGi Auto Drain Valves for compressor systems ensure continuous, automatic removal of condensate through zero loss drain valve technology without compressed air loss protecting the entire system.

How ELGi Auto Drain Valves Work

ELGi drain valves operate on zero loss drain valve principles, ensuring that only condensate is discharged.

Level-sensing drain valves detect the actual accumulation of condensate and open only when liquid is present, closing immediately after discharge.

Timer-based drain valves use adjustable on/off cycles for controlled condensate removal where required.

Unlike conventional drains that continuously bleed compressed air, efficient drain prevent unnecessary air loss, resulting in significant energy savings.

Types of ELGi Auto Drain Valves

Compact Timer Drain Valve

Equipped with an ultra-reliable microcontroller, the compact timer drain valve offers adjustable on/off timing for controlled condensate discharge. A specially designed orifice and solenoid operator ensure effective removal of condensate and dust while allowing easy maintenance.

Key benefits:

  • Adjustable drain intervals
  • Easy installation and servicing
  • Suitable for general compressed air applications

Level-Sensing Drain Valve

ELGi’s level-sensing drain valve represents the latest advancement in condensate management. Instead of relying on timers, it activates purely based on condensate level—ensuring true zero-loss drain valve operation.

Key benefits:

  • No compressed air loss
  • Significant energy savings
  • Reliable and highly efficient operation
  • Direct replacement for manual drains

Key Features & Advantages
