Choose the right type for you — from simple timer drains to intelligent zero-loss units that eliminate compressed air waste.
The Business Case
Compressed air comes at a real cost — and if your condensate drain wastes air every time it fires (whether condensate is present or not), that cost adds up fast.
On larger compressed air systems, a poorly chosen drain can result in hundreds of pounds worth of compressed air wasted annually — per drain point. Multiply that across a typical plant room and the numbers become significant.
The choice of drain isn't just about capital cost — it's about the total cost of ownership over the life of the installation.
The right drain depends on your system pressure, condensate volume, pipe size and whether the drain point is accessible. Contact us and we'll help you specify the correct model.
Every time a timer drain opens — even when there's no condensate — it releases a pulse of compressed air to atmosphere. Set too frequently, this becomes significant wasted energy.
The Range
Timer-operated solenoid drains are the traditional approach — simple devices that open on a set schedule to release condensate. Lower capital cost makes them attractive where air loss is acceptable or the system is small.
Level-sensing zero-loss drains capture condensate, then discharge it as required — with little or no waste of compressed air. They only open when condensate is actually present, eliminating unnecessary air loss entirely.
