INTRODUCTION
An air ow amplier uses a small amount of compressed
air to move a much larger air volume. Amplication ratios
may meet or exceed 20:1. For more details on airow of a
specic unit, visit www.vortec.com, or contact your local
distributor or Vortec.
COMPRESSED AIR SUPPLY
The compressed air supply must be ltered to remove
water and dirt using a 5 micron or smaller lter. Failure
to use a lter may cause clogging of the compressed air
paths inside the Vortec product. Filter recommendations
are given in Table 1.
Filter elements must be changed on a regular basis.
Frequency of change is determined by the condition of
the compressed air supply. Filters should be installed in
the compressed air supply line as close as possible to
the Vortec product.
The appropriate size of the compressed air supply line
should be selected to ensure optimal performance of the
Vortec product. Please refer to Table 2 to determine what
supply line size is recommended for your application.
Contact Vortec at 1-800-441-7475 for further assistance.
OPERATION
In order to vary the volume of airow from the air ow
amplier, an appropriately sized pressure regulator
can be used to control the compressed air pressure,
(less pressure = less airow). (Pressure regulator
recommendations are given in Table 1.)
The output airow volume can also be adjusted by varying
the internal air gap. For models with shims (901A, 901BA,
901DA, 901HA, 902, 903, 904), this is accomplished
by adding or removing gap shims (see Table 1). In
adjustable model 909A, this can be accomplished by
rotating the outlet barrel (counter-clockwise will increase
airow, clockwise will decrease airow).
INSTALLATION AND MAINTENANCE
Air ow ampliers can be installed by directly plumbing
to the appropriately-sized, hard piped, compressed air
source that does not exceed 150 psig (10.3 Bar), see
Table 2.
When using air ow ampliers for ducting fumes or
smoke, the duct must be sized, and routed to prevent
back pressure totaling more than 2” of water column.
Back pressure in ducted airow will substantially affect
performance.
It is critical to the performance of the air ow amplier
that the internal air passages remain clean. If the air
ow amplier’s performance suddenly drops, carefully
disassemble the unit and inspect for debris. If debris is
found, it may be necessary to change your lter element.
Clean the debris from the unit and reassemble. Use
caution during reassembly to ensure that the shim (where
applicable) remains centered and does not become
lodged in the air passage. For detailed instructions
on cleaning or reassembly, contact your authorized
distributor or Vortec.
TROUBLESHOOTING
Insufficient airow may be caused by the following:
1. Undersized compressed air line size.
2. Compressed air pressure too low.
3. Partial or complete blockage of internal air path,
due to dirt. See Maintenance section for cleaning
instructions; and Compressed Air Supply section for
lter recommendations.
4. Insufficient compressed air volume.
If trouble persists, please contact Vortec at 1-800-441-
7475.
1. Do not operate air ow ampliers at compressed
air pressures above 150 psig (10.3 Bar).
2. Do not operate airow ampliers at line
temperatures above 110oF (43oC).
3. Avoid direct contact with compressed air.
4. Do not direct compressed air at any person.
5. When using compressed air, wear safety glasses
with side shields.
