Automatic Condensate Drains for Compressed Air Systems

Automatic drains discharge collected condensate from air receivers, filters, air dryers and compressed air lines without relying on manual draining. Effective condensate removal helps prevent corrosion, contamination and water carryover.

Choose the Correct Automatic Drain

Thread

Confirm the Connection

Check the inlet and outlet thread sizes before ordering.

Voltage

Match the Electrical Supply

Confirm the coil voltage and whether the supply is AC or DC.

Function

Normally Open or Closed

Make sure the valve function matches the intended installation.

Protection

Use a Strainer

A strainer helps prevent dirt and debris from blocking the valve orifice.

Why Automatic Drains Are Important

Prevent condensate building up inside receivers and pipework.
Reduce corrosion and moisture-related equipment damage.
Protect filters, dryers, air tools and production machinery.
Support consistent compressed air quality and performance.
Reduce the risk of missed manual drain checks.

Timer drains release a small amount of compressed air during each discharge. Set the open time and interval carefully to remove condensate without unnecessary air loss.

Installation and Maintenance Guidance

Isolate and depressurise the compressed air system before installation.
Disconnect the electrical supply before wiring or servicing.
Confirm voltage, valve function and flow direction.
Install a suitable strainer upstream of the valve.
Use appropriate thread sealing without allowing material into the valve.
Test the drain and check for leaks before returning the system to service.

Automatic Drain FAQs

What does an automatic drain do?

It automatically releases condensate collected in compressed air receivers, filters, dryers or pipework.

How does a timer-controlled drain work?

It opens for a set duration at regular intervals. The interval and open time should match the condensate load.

Why is a strainer important?

A strainer helps stop dirt and debris from entering and blocking the solenoid valve.

Can I choose a drain by thread size alone?

No. Confirm voltage, valve function, operating pressure, thread type, flow direction and application.

Where can an automatic drain be installed?

Common locations include air receivers, compressed air filters, refrigerated dryers and low points in pipework.

Why has my drain stopped working?

Common causes include incorrect voltage, a failed coil, a blocked orifice, damaged seals, contamination or wiring faults.
