AIr COnneCTIOnS
An Air Line (Item 20) is furnished and air controls with 1/8
NPT ports are recommended. Where long air lines are
required, a Quick Exhaust Valve (Product No. 945100) is
recommended to ensure rapid disengagement.
NOTE: Because of the necessary movement of the air
chamber and Air Line upon engagement, flexible
tubing or air lines must be used on the Air Champ
II.
Due to bearings seal drag, the outer portion or the Air
Champ II will rotate when it is engaged. Rest the air line
against a support that is parallel to the centerline of the Air
Champ II to stop this rotation.
NOTE: Pressure should be regulated to the minimum
required for sufficient torque to maximize bearing
life.
nOTe
For quick response, nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers
of the product.
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.
The following is a common air supply 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.

WARNING
Never exceed maximum operating
speeds listed for your product.
(See Table 6).
CAUTION
The temperature limits for this
product line are 4.5-100 Degree
Celsius (40-220 Degree F).
CAUTION
Never exceed life of facing material. Facing
life depends on the volume of material and
the total energy over the life of the unit.
Expected life (in hrs) can be found by:
Time=Volume/(Power*Wear Rate).
