AIR LINE CONNECTIONS
Nexen’s EN40 requires clean, pressure regulated air for maximum performance and long life. Nexen offers a filter
that is ideally suited for the needs of the EN40 (See PRODUCT NUMBERS section).
A pre-filter, rated at 5.0 micron or less is used to remove large particles from the air supply. The coalescing filter,
rated at .1 micron or less, is then used to final filter the air before it enters the EN40 (See Figure 9).
NOTE: Airline lubricators must be installed after EN40.
