Concrete Form
On a Concrete Form:
The rotation of
vibrator roller (weight) is counterclockwise.
This helps force the air bubbles to the surface.
Facing the concrete form the shaft/hose barb
will be on the right.
O
n a Hopper Wall:
The direction of rotation is
in the direction of material flow - the roller weight
rotates toward the hopper and down. Facing the
hopper, the shaft/hose bard will be on the left.

VII. Vibrator Orientation
Whenever possible, mount the vibrator with the
shaft in the horizontal position.
To ensure proper direction-of-rotation, the GCL
vibrators are assembled for either a hopper or a
concrete form application. This only applies to the
GCL due to the way it sits in its bracket. To reverse
direction of rotation, the shaft and side plates must
be removed and swapped, so that, the shaft air
inlet is on the opposite side of the housing. Always
observe vane and exhaust port orientation. See
page 7, Note 2).
The direction of rotation is determined by looking
at the side plate with the hose barb and exhaust
slots. The air enters the vibrator through the shaft
and pushes up the vane. (The vane is opposite the
keyway in the shaft.) The slots in the vane force
the air to one side only. The air carries the inner
roller with it as it travels around the shaft to get to
the exhaust slots. If the vane is facing the wrong
direction the air will have a direct path to the
exhaust without having to circle the shaft. If the
vane is not on the top of the shaft, but instead on
the side or bottom, the weight of the roller will not
press the vane back into the shaft and the vibrator
may not start.
