Removing an Air Lock
If too much air gets into the sheath filter, it becomes impermeable to fluid and an
air lock can develop. Although it is most likely to occur for the sheath filter, an
air lock can develop in any of the fluidics filters.
Materials
• paper towels
• bypass tubing
Procedure
1 Place a few paper towels beneath the air-locked filter to collect drips.
2 Remove the filter by pressing the metal tabs.
