Use cases & applications
Continuous-Duty Vacuum Pump Protection
In applications where Leybold SogeVac pumps run continuously, such as in packaging or plastics processing, this separator efficiently removes liquid and particulate carryover. Its compact 73 mm diameter and 488 mm height fit easily into tight machine enclosures, reducing downtime for maintenance.
High-Contaminant Environments
For industries like chemical processing or food packaging where oil mist and debris are prevalent, the separator's design ensures reliable separation without clogging. The 44 mm inner diameter allows consistent flow, extending pump life and oil change intervals.
Multi-Machine Inventory Consolidation
If your facility operates several Leybold SogeVac models (SV 300 B through SV 750 B), stocking this single aftermarket separator simplifies inventory. Its cross-reference to multiple brands means one part number covers pumps that previously required different branded filters.
Budget-Conscious Maintenance Schedules
For workshops that perform regular preventive maintenance on Leybold vacuum pumps, this aftermarket separator provides a lower-cost option without sacrificing fit or function. Its 0.62 kg weight makes it easy to handle during quick changeouts, reducing labor time.
