Automatic Drains

Automatic Condensate Drains for Compressed Air Systems

Automatic drains are essential components in compressed air systems, designed to remove condensate – typically a mixture of water and compressor lubricant – from air lines, filters, air receivers and dryers. Effective condensate removal helps prevent corrosion, contamination and costly damage to downstream equipment.

By automatically discharging collected liquid, these drains maintain system efficiency, protect air tools and machinery, and ensure consistent operating pressure in industrial and workshop environments.

Types of Automatic Drains

• Timer-controlled drains – open at pre-set intervals to discharge condensate
• Thermostatic drains – operate based on temperature changes
• Zero-loss electronic drains – discharge condensate without wasting compressed air

Timer drains are suitable where condensate volumes are predictable, while electronic and thermostatic options are ideal for systems with fluctuating load, temperature or humidity.

Why Automatic Drains Are Important

• Prevent water build-up in compressed air pipework
• Reduce corrosion and internal system damage
• Maintain consistent air pressure and performance
• Protect air tools and production equipment
• Improve overall system efficiency

Failure to remove condensate can result in corrosion, reduced air quality, increased maintenance costs and unexpected breakdowns. Moisture in compressed air systems can also create safety risks and negatively impact sensitive equipment.

Reduce Downtime & Maintenance Costs

Installing the correct automatic condensate drain helps extend the lifespan of your compressed air system. By preventing moisture-related damage, you reduce repair frequency, minimise downtime and improve long-term reliability.
