AIR CONNECTIONS

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.

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

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.

The following is a common air supply scheme used with
