Maybe you are looking for the Stryker 986-500 filter cartridge. This model has been replaced by the unit shown next to it in the photo!
This is the updated and improved Stryker 986 CastVac Generation ll filter cartridge. Stronger, quieter and more effective than it’s forerunner. Uses a “pre-filter” foam “silencer” that reduces sound output, and permits better airflow through the system.
