The above pic shows a dual filter arrangement for industrial testing, NEW EMS filter Hous-
ing assembly is part #: EMS-5370-Dual Assy. 2x (External particulate) and Water Trap assembly
is part # EMS-5372 (EMS-5371 coalescing filter). Maintenance procedures are described below:
1. The External Filter should be checked often (Figure 36; EMS-5371). This filter catches
most of the particles and impurities. The life-cycle of this filter depends on usage, but the average
shop replacement is 3 months. To determine the correct replacement interval for your shop, check
the filter once a month (EMS-5070). The water trap filter is the same coalescing filter with the
sample gas flow from inside out, so NO contamination can be visibly seen as with the external
filter. The water trap filter is a disposible filter and should be changed every 3 months.
Filter Replacement:
a. Remove the filter bowl turning clockwise to loosen the bowl.
b. Rotate the filter retainer below the filter clockwise to remove.
c. Replace the filter and re-screw in the retainer turning counter-clockwise.
d. Re-install the filter bowl tighening counter clockwise.
e. The water trap bowl is the same as the external filter only that the water drain hise
needs to be disconnected and re-connected after filter replacement.
f. Do a leak check to make sure of NO leaks.
