WARNING: COMPRESSED AIR COULD CAUSE DEATH,
BLINDNESS OR INJURY
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 110°F (43°C).
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.
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).
GENERAL SAFETY CONSIDERATIONS

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
Insucient 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. Insucient compressed air volume.
If trouble persists, please contact Vortec at 1-800-441-7475.

Table 2: Determining Compressed Air Line Size
1. Calculate total product compressed air consumption (SCFM, SLPM).
2. Determine length of compressed air line required for connection to main supply.
3. Locate pipe length in left column and read to the right to nd the compressed air requirements.
4. Locate pipe size at top of column.
