Product Description
The Wagner A21857 Air System Moisture Ejection Valve is designed to remove accumulated water and condensation from compressed-air reservoirs.
During normal system operation, moisture collected in the air reservoir enters the valve chamber and is discharged to the atmosphere as the air system cycles. This helps keep air tanks cleaner and drier and reduces moisture buildup within the compressed-air system. AMETEK’s service literature describes the moisture ejection valve as automatically expelling accumulated moisture from the reservoir.
The legacy valve is also cataloged as A021857 and is associated with Wagner AE21882. These older versions are obsolete, with J107084 identified as the replacement moisture ejection valve.
