AIR CONNECTIONS

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.

All Nexen pneumatically actuated devices require clean,
dry air that meets or exceeds ISO 8573.1:2001 Class
4.4.3 to quality.

CAUTION

Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.

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.

Use the length of 5/32" [4 mm] O.D. nylon air line air line
that is supplied to make the connections between the cali-
pers. (See Table 3 for Air Line Specifications).

REFER TO FIGURES 11 - 12.

1. Screw the Rotary Air Union assembly into the shaft

end.

2. Install the air line by pushing it into the fitting until

it stops. The Elbow and Tee Fittings (Items 15 and
16) are push-lock fittings for instant connection and
disconnection.

To disconnect, first push the fitting collar in and then
pull the air line out. Make certain that all fittings are
properly tightened.

NOTE

Each caliper comes with one elbow fitting,

two tee fittings and 13.5" [34.3 cm] of air line

tubing. Not all of the fittings are used to make

caliper connections. Save the extra fittings for

replacement parts.

2. Route the air lines from the Rotary Air Union to the

individual caliper assemblies (See Figure 4).
