Continuous-Duty Industrial Vacuum Pumps
In applications where Elmo Rietschle pumps like the CLFD 251 or VSH 250 run continuously, this cartridge ensures consistent airflow and protects internal components from particulate ingress, reducing unplanned downtime.
Harsh Dusty Environments
For pumps operating in woodworking, cement, or grain handling facilities, this cartridge traps airborne debris effectively, extending the service life of the pump and maintaining vacuum efficiency.
Maintenance Scheduling Simplification
By standardising on this single filter cartridge across multiple Elmo Rietschle models (e.g., CLF 181, VTB 251, DTB 250), maintenance teams can consolidate inventory and streamline replacement intervals.
Retrofit for Older Pump Models
Owners of older units like the 2001 CLFD 181 or VSH 180 can replace worn or obsolete filters with this modern aftermarket cartridge, restoring original performance without costly OEM parts.
Check your pump's model number and year of manufacture. This cartridge fits models including CLFD 181 (2001), CLFEH 181, CLF 251 (2001), VSH 250 (2001), and many others listed in the compatible machines section. If your model is not listed, please contact us with your pump details.
The product specifications provide a permissible flow of 40 m³/h and dimensions, but the exact filtration rating (micron level) is not stated. It is designed as a direct replacement for the original equipment, ensuring comparable filtration performance.
The cartridge has an outer diameter of 67 mm, total height of 71 mm, largest inner diameter of 38 mm, and smallest inner diameter of 4.5 mm. These dimensions match the OEM specifications for the listed Elmo Rietschle models. Verify your housing dimensions against these.
This is an aftermarket replacement, not an OEM part. It is built to match the original specifications of Elmo Rietschle filters, providing a reliable and cost-effective alternative to branded parts.
Replacement intervals depend on operating conditions and environment. Inspect the cartridge regularly for visible dirt or damage. In dusty environments, more frequent changes may be needed. Always follow your pump manufacturer's maintenance guidelines.
