Moisture Separators: Moisture Separators and Float Drains are the final step in removing moisture from compressed air after its been cooled and has condensed. Compressed air is spun thru a centrifugal separator whereby the remaining suspended moisture collects against the walls of the unit and falls down toward the drain / trap. Moisture separators must be mounted in a vertical configuration.
Float Drains: Once the moisture has been separated from the compressed air, a float drain either automatically or manually discharges the liquid while maintaining the pressure of the compressed air system.
