8.1 Cleaning the STAP
The filters used in the STAP shed fibers that can contaminate windows and sealing sur-
faces. During each filter change, visually verify that no filter debris is loose inside the
unit. Clean filtered air can be used to blow out the channels to remove debris.
If windows within the STAP become dirty, use a Q-tip soaked in IPA to clean them.
O-rings inside the STAP will become dry with use. Apply fresh grease to the O-rings
exposed during filter changes roughly every 15 filter changes. Visually inspect the o-
rings for damage and replace any that appear cracked or deformed.
Under persistent high aerosol loading conditions, the sample LFE may become clogged
or partially blocked with particles. Remove the LFE from the unit and flush with clean DI
water and IPA. Sonicate for 2 hours submerged in water. Blow dry with filtered air after
sonication and re-install.
