Water accumulated in the air tank should be drained as frequently as possible. In time, because of the pressure, water vapor condenses and water accumulates inside the air tank.
How to discharge water from the air tank?
Under the air tank, a valve or a blind plug is installed by the manufacturer. This is used to discharge water from the air tank. By attaching a water hose to this plug or valve, you can drain the tank in daily, weekly or self-attained time periods. Direct the drained waste water to a cap. Before drainage, make sure that air tank is nor pressurized. If drainage is done while there is still pressure in the air tank, drainage of waste water will pressurized and water will spread.
Automatic discharge systems
These are the electrical systems that are attached to the discharge valve. They are automatic systems that drain water inside the air tank without requiring any human interaction. They collect the drained water in their inner mechanisms and by means of their sensors, save energy by discharging the water only when required.
Drainage with solenoid valve and intermittent relay
This system also provides an automatic drainage mechanism. It is possible to automatically discharge the system with the help of an intermittent relay and a solenoid valve, which is installed on the drainage valve. However, this mechanism is quite complicated and while discharging water, significant amount of air will also be discharged. Unnecessarily discharged air will cause your compressor to run longer periods of time hence cause waste of energy.
Drained waste water
Wastewater contains a variety of materials such as oil, welding powder, water, dust and bacteria. It is not considered a suitable to discharge the wastewater to nature directly. Special filtering procedures should be applied before release.
