AIR CONNECTIONS
The following is a common air supplied scheme used with
this product. This is an example and not an all-inclusive
list. All air circuits to be used with this product must be
designed following EN983 guidelines.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
NOTE
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.
Nexen product's bearings are shielded and pre-lubricated, and require no further lubrication.
LUBRICATOR DRIP RATE SETTINGS
1. Close and disconnect the air line from the unit.
2. Turn the Lubricator Adjustment Knob counterclockwise three
complete turns.
3. Open the air line.
4. Close the air line to the unit when a drop of oil forms in the
Lubricator Sight Gage.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob clockwise until
closed.
7. Turn the Lubricator Adjustment Knob counterclockwise one-
third turn.
8. Open the air line to the unit.
LUBRICATION
CAUTION
These settings are for Nexen supplied
lubricators. If you are not using a Nexen
lubricator, calibration must follow the
manufacturer's suggested procedure.
Note
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the unit. Align the air inlet ports to a down position to
allow condensation to drain out of the air chambers of
the product.
