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.
All Nexen pneumatically actuated devices require clean and
dry air, which meets or exceeds ISO 8573.1:2001 Class
4.4.3 quality. The following are common air supply schemes used with
this product. These are examples 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.
NOTE
Do not use rigid pipe or tubing for this connection.
For fast engagement and disengagement,
connect air controls as close to the DPC Clutch
as possible. Where long air lines are required,
use a quick exhaust valve.
