Use cases & applications
Continuous-duty construction sites
On busy construction sites where Atlas Copco compressors like the XA 65 run for extended periods, this separator ensures reliable separation of moisture and contaminants, reducing downtime for filter changes.
Remote operation with limited maintenance access
For compressors operating in remote areas, such as the XAS 35, this separator's robust construction helps extend service intervals, minimising the need for frequent maintenance visits.
High-humidity environments
In coastal or humid conditions, the separator effectively removes water from compressed air, protecting downstream equipment when used with Atlas Copco XASS 55 compressors.
Fleet maintenance consolidation
Workshop managers servicing multiple Atlas Copco models including XA 45 and XAS 55 can stock one separator part number, simplifying inventory management and reducing stock holding costs.
