Nexen DFC-1650 964149 - Manual (Page 6)

6 FORM NO. L-20312-C-0110
NOTE
Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance and life.
All seals in Nexen pneumatically operated devices are lubricated for life, and do not require additional lubrication.
However, some customers prefer to use an air line lubricator, which injects oil into the pressurized air, forcing
an oil mist into the air chamber. This is acceptable, but care must be taken to ensure once an air mist lubrication
system is used, it is continually used over the life of the product as the oil mist may wash free the factory
installed lubrication.
Locate the lubricator above and within ten feet of the product, and use low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
LUBRICATOR DRIP RATE SETTINGS

in the Lubricator Sight Gage.
5. Connect the air line to the unit.
