General Information
The XL 10000 air motor is air piloted with two poppet
valves operating a cup and plate main air shuttle valve.
Air exhausts around the cylinder, through sound absorp-
tion materials, and out the rear bottom of the shroud.
Application
This motor has 7% larger effective area, and is intended
to directly replace, the Graco Premier® motor. The XL
will acceptthesameM16x 2.0 threaded tie rods, the
same connecting rods, and the same 3/8-16 mounting
studs used with the Premier. The XL motor is physically
smaller than the Premier, so it will fit anywhere the Pre-
mier is used. The 1 in. air inlet is at a low front position
instead of up on the top so a different air hose may be
required. There are also threaded cart/shelf type mount-
ing holes in the base which match the ones used on the
NXT® motors. The XL motor fits the standard heavy
duty Xtreme cart so the larger Premier cart is no longer
necessary.
Reciprocating Signal Poppets
The poppets are identical to the ones used in the Graco
Merkur® motors and many air-operated double dia-
phragm motors. Poppets are fully accessible and can
easily be replaced.
External Pilot Lines
The pilot lines (L) that run from the shuttle end ports to
the exhaust poppets are run externally in hydraulic
hose. This allows for cold weather operation without
running the air through the aluminum manifold, which
can sometimes get cold enough for airline moisture to
freeze and block the signals.
Manual Override Buttons
There are manual override buttons (F) on each end of
the air valve that allows the internal main shuttle valve to
be physically moved from one position to the other. Run
the motor manually to:
•
Move the valve off center due to ice or debris.
•
Flush a pump if a poppet is plugged, stuck in the
open position, or the signal is leaking.

Low Pressure Operation
This motor will run at 4–5 psi (20.6–27.5 kPa, 0.21–0.27
bar)
Performance
The air valve (A), manifold (E), and exhaust are larger
than the Premier air handling parts in order to exhaust
the 630 in3 of compressed air from the cylinder after a
full stroke. This allows the • uid pressure to come back
faster as the piston is driven from the other side. The
near square pressure trace that this generates makes
for a small change-over pulse, and full pressure output
for running multiple guns.
Minimum Icing
The oversizing of all the air handling parts described in
the General Information section mean that normal air
motor ice buildup has less effect on the pump output.
Bleed Air
Use the de-ice bleed air valve (M) to run warm air
through the valve and exhaust for de-icing. This is
mainly helpful during warm weather, very high humidity
applications, or low pressure high cycle rate applica-
tions.
Extended Capabilities
The XL motor will accept DataTrak™ counting, a run-
away stop solenoid, and the top mount linear position
transducer used with NXT motors.
