When the compressed air cools, part of the moisture sucked in by the compressor condenses. In order to protect the dryer against
the risk of an ice plug forming, it is essential to check regularly that the condensate drains are operating properly :
On the compressed air storage reservoir and on the filters :
• With a manual drain, drain regularly according to the moisture content of the ambient air.
• With an automatic drain, set the draining cycle accordingly and check that the drain is in good working condition.
This recommendation is also fundamental in a circuit comprising an absorption dryer (risk of saturation of the alumina).
