The 33XP filter assembly and heating system do not require routine maintenance.
The filter element requires periodic replacement, depending upon application and dust loading. See the attached spare parts list for replacement elements.
If the 33XP is used in conjunction with the Baldwin™-Series Flow Control Drawer, monitoring the sample vacuum will allow the operator to determine when to change the filter element. The operator can log the baseline vacuum reading when the system is first started with a new filter element.
If the sample vacuum is consistently 25% higher than at start-up, the operator should replace the filter element with a new filter. Visual inspection will also confirm the condition of the filter element.
The filter incorporates a “jack screw” that helps to remove the filter cap in case it becomes stuck due to buildup of debris inside the housing. Turning the thumbwheel counterclockwise will force the cap away from the housing and allow for easy removal of the element.
