Condensate drains, or pneumatic drains, are a type of valve which is used to remove condensate from a pneumatic system. As the air cools within a system, the humidity within the air turns to condensate. It is important to remove condensate from an air system as water can cause damage and corrosion. Condensate drains are commonly used in pneumatic air preparation and compressed air treatment systems.
Condensate drains are available in a range of sizes and volumes depending on the system they're compatible with and how heavy-duty the application they're needed for is. Particularly useful are automatic drains, which reduce the risk of forgetting to empty the drain.
Condensate drains can be used in all kinds of pneumatic systems, for example in factories. They work in conjunction with filters to remove contaminants or to prevent them from building up in a pneumatic system. Excess lubricant, metal particles, rust and scale can be separated out from the system by filters, and then removed via a drain.
Condensate drains can be installed at low points in the system to help stop condensation collecting. They reduce the risk of damage to expensive equipment and the need for downtime.
