Maintenance
The membrane module inside the Nitrogen Generator is designed to operate maintenance-free as long as the prefilter
and coalescing filters effectively remove impurities (particularly oil vapor) from the feed air.
A slide indicator on these filters changes color (from green, to yellow, and then to red) when the filter element inside
either unit needs to be replaced (see Figure 1). This indicator should be monitored monthly. Under continuous use at
100 PSI, filters will operate for approximately two years (20,000 hours).
Replacing Filter Elements
1.
Open the front housing panel of the Nitrogen Generator to expose the filters (see Figure 1).
2.
Rotate the self-locking bayonet head 1/8 turn counterclockwise to release it from the bowl (see Figure 2).
3.
Pull the filter element to release it from the head. Remove the bottom filter element cap.
4.
Attach the bottom cap to the replacement filter element and push it into the filter head until it locks in place.
5.
Rotate the filter head 1/8 turn clockwise to reattach it to the filter bowl. Close the front panel.
