IV. Operation
Global High Frequency External Vibrators are
pneumatic with dual rollers. Their ease of operation
and low maintenance is due in part to the fact that
these vibrators contain no bearings or motors.
The vibrator may run continuously at speeds
up to the rated running conditions shown in our
performance data. Use a ball valve or solenoid
valve to turn the vibrator on and off. A regulator
provides constant speed control even as the plant
air pressure varies.
Install a filter, regulator, gauge, and lubricator in
the air line within 10 to 12 feet (3 - 3.7 m).
Filtration
Do not connect the vibrator directly to plant air. Use
a 64 micron filter. Drain the airline filter regularly
and examine the element for signs of clogging.
Regulation
Operate the vibrator on filtered, regulated, lubricated
air between 40 - 80 psi (2.8 - 5.5 bar) at 45 - 60
cfm (21 - 28 Lps).
Lubrication
Use a lightweight lubricant. Replenish the airline
lubricator as required and set to give the following
drop rate minimum. Will operate in temperatures
of 32° F (0° C) to 250° F (120° C).

Pipe and Hose Connections
The vibrator has a barb fitting to accept a ¾"
I.D. hose. Clamp the hose securely to the fitting
with a Band-It, Punch-Lok
®
, or a similar clamp. A
worm driven clamp is not recommended since the
vibration may cause the clamp to loosen and allow
the hose to blow off the fitting.
The table below shows the recommended hose size
according to the amount of air required.

If the vibrator will be moved or disconnected
frequently, a hose whip is recommended (see
illustration below). The whip is a short piece of hose
(12" - 18") atttached to the shaft with a clamp.
Attach a quick coupling, such as a Dixon
®
hose
coupling, to the free end of the whip. Add a ball
valve to the plant air line to shut off the air before
disconnecting the quick coupling.
V. Assembly & Disassembly
For proper vibration operation, it may be necessary
to change the direction of rotation or the position
of the vane. Both the GCD and GCL models are
disassembled and assembled in the same manner.
