When compressed air cools, it forms condensate (water + oil mixture). If not removed, it can:
- Damage machines
- Reduce efficiency
- Cause rust and contamination
The auto drain valve solves this by draining condensate automatically—no need for manual draining.
Types of Auto Drain Valves
- Timer-Based Auto Drain Valve
- Works on set intervals (e.g., every 30 mins)
- Simple and affordable
- Common in small to medium setups
- Float Type Auto Drain Valve
- Drains only when water reaches a certain level
- No air loss (more efficient)
- Ideal for air receivers and dryers
- Zero Loss Auto Drain Valve
- Advanced version of float type
- Drains condensate without losing compressed air
- Best for high-efficiency industrial systems
