Clean Air Outlet

Filter Gauge
Verify clean air outlet is not ob-
structed and discharge air appears
clean (free of welding fumes).
Check filter if discharge air appears
dirty. Make sure cover is closed
(and latched) to ensure a tight seal
around the filter.
Check filter gauge. Replace filter
when reading is over 4 in. w.c. (10
x 100 Pa) or whenever air flow is too
low to extract fumes.
