Shimadzu, 228-54509-02, DGU-20AR Intake Air Filter, 2/PK

Shimadzu DGU-20AR Intake Air Filters are replacement dust-control elements for the air intake of the DGU-20AR solvent degassing unit. The pack contains two filters used to help keep airborne particles from entering the instrument housing through its designated intake openings. Accumulated dust can impede airflow and compromise normal operation of equipment that depends on unobstructed ventilation. Inspect the installed filters during routine preventive maintenance, particularly where laboratory air contains visible dust or the equipment is used continuously. Turn the instrument off before servicing its air intake and replace soiled elements without allowing loose debris to enter the enclosure. Keep ventilation openings clear when positioning the degasser among other liquid chromatography modules. These intake filters are not solvent-path membrane cartridges, vacuum tubing filters or HPLC mobile-phase inline filters. They serve the DGU-20AR air intake rather than filtering the sample or solvent flowing through the chromatographic system.
