The Atlas Copco EWD 330 Auto Drain Valve is a high-performance electronic condensate drain specifically engineered for efficient removal of moisture and condensate from compressed air systems. Operating within a pressure range of 0 to 16 bar, it ensures reliable performance across various industrial applications.

This advanced drain valve uses intelligent electronic controls to discharge condensate only when required, preventing unnecessary compressed air loss and improving overall system efficiency. Its zero-air-loss design helps reduce energy consumption and operational costs while maintaining optimal air quality.

The EWD 330 features a robust and compact design, making it suitable for installation in air compressors, dryers, filters, and receivers. It is built with high-quality materials to withstand harsh industrial environments, ensuring durability and long service life.

Efficient Automatic Condensate Removal for Compressed Air Systems

The Atlas Copco EWD 330 Auto Drain Valve is an advanced electronic condensate drain solution designed to automatically remove water, oil, and contaminants from compressed air systems. During the compression process, atmospheric moisture condenses into liquid water inside compressors, air receivers, filters, and dryers. If this condensate is not removed efficiently, it can lead to corrosion, equipment damage, pressure loss, and reduced air quality.

Unlike manual drain valves that require regular operator attention, the EWD 330 automatically senses condensate levels and discharges only the liquid while preventing unnecessary compressed air loss. This intelligent operation improves compressor efficiency, reduces energy consumption, and minimizes maintenance requirements.

The Atlas Copco EWD 330 is widely used in industrial compressed air systems where reliable condensate management is essential for maintaining productivity and equipment reliability.

At Airmake Solution, we supply OEM-quality Atlas Copco EWD 330 Auto Drain Valves that deliver dependable performance, long service life, and efficient condensate removal for industrial applications.

How Atlas Copco EWD 330 Works

Step 1 – Condensate Collects

Water, oil, and contaminants accumulate inside the compressor or compressed air equipment.

Step 2 – Sensor Detects Liquid Level

The electronic sensor continuously monitors condensate levels.

Step 3 – Automatic Draining

When condensate reaches the preset level, the valve opens automatically.

Step 4 – Condensate Discharges

Only liquid condensate is discharged while compressed air remains inside the system.

Step 5 – Valve Closes Automatically

The valve closes immediately after drainage, maintaining maximum system efficiency.
