Pneumatic Level Sensing Drains for Compressed Air Systems

Pneumatic level sensing drains are crucial for automated condensate management in compressed air, refrigeration, and pneumatic systems. These drains use air pressure differentials to detect liquid accumulation and open a valve only when necessary. They offer energy savings, have no air loss and minimal manual oversight.

Key Features & Advantages

• Pressure‐activated sensing: Responds to rising liquid levels without electrical components.
• High pressure tolerance: Typically rated for 44–230 PSI, suitable for most industrial compressed air lines.
• Threaded ports: Fittings such as 1/2" & 3/4" NPT
• Reliable condensate removal: Prevents water pooling which can cause corrosion, freezing, or loss of efficiency.

When to Use Pneumatic Level Sensing Drains

• In systems where electricity is unavailable or undesirable.
• Where leakage from conventional timed drains is costly.
• In environments needing low maintenance and continuous, reliable condensate control.
