GENERAL SAFETY CONSIDERATIONS
WARNING: COMPRESSED AIR COULD CAUSE
DEATH, BLINDNESS OR INJURY
1. Do not operate Stainless Steel Air Flow Ampliers
at air pressures above 150 psig (10.3 Bar).
2. Do not operate Stainless Steel Air Flow Ampliers
at line temperatures above 400
o
F (205
o
C) without
removing internal O-Ring. Once O-ring is removed,
operation up to 800
o
F (427
o
C) is permitted. Any
resulting air leak is minimal and will not noticeably
affect the performance.
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.
NOTE: There is no need to limit compressed air pressure
to a maximum of 30 psig (2 bar). It is not possible to
block the ow of air from the airow amplier to register
30 psig (2 bar) on a test gauge.
INTRODUCTION
A stainless steel
Air Flow Amplier
uses a small amount
of compressed air to move a much larger air volume.
Amplication ratios may meet or exceed 19:1. The output
air volume can be easily adjusted - see the Operation
section.
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 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.
INSTALLATION
Air Flow Ampliers 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 the Air Flow Amplier is to be used in the ducted
applications for fume or smoke removal, the duct should
be sized to provide a ow resistance of less than 2 inches
of water column. Ducting resistance can be minimized
by using large diameter ducts for long runs, avoiding
restrictions and making large radius bends. Ducting
resistance can reduce the Air Flow Amplier’s discharge
airow, substantially affecting product performance.
MAINTENANCE
To verify lter element changing frequency, inspect the
inside of the Air Flow Amplier periodically (6 months or
less).
1. Unscrew the knurled locking collar.
2. Unscrew the two body components.
3. If dirt is observed, clean all parts and shorten the lter
element changing frequency.
4. Reassemble, setting the gap between the two body
components to give required performance. If in doubt,
set gap at 0.002” (0.05mm).
Markings from 0 to 10 on the unit indicate the gap size
(Example: 4 = 0.004”).
5. Reassemble knurled locking collar onto the two body
components.
OPERATION
In order to vary the volume of airow from the Air Flow
Amplier, an appropriately-sized pressure regulator can
be used to control the compressed air pressure, (less
pressure = less airow).
The output airow volume can also be adjusted by varying
the internal air gap. This is accomplished by loosening the
knurled locking collar and rotating the outlet barrel counter
clockwise to increase airow, clockwise to decrease
airow).
TROUBLESHOOTING
Insufficient airow 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 compressed 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.
