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 ISO 4414 guidelines.
AIR CONNECTIONS
To prevent air line breakage, rest the air line against a support
mounted parallel to the Multiple Disc Clutch.
NOTE: Rigid pipe or tubing when connected directly to the
Multiple Disc Clutch will prevent proper actuation
of the Multiple Disc Clutch. Use only flexible hose
or tubing when making air line connections.
OPERATION
WARNING
Never exceed maximum operating
speeds listed for your product.
(See Table 1).

WARNING
Ensure proper guarding of the product is
used. Nexen recommends the machine builder
design guarding in compliance with OSHA 29
CFR 1910 “Occupational Safety and Health
Hazards”.
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).
