OperatiOn

Dual action PaC:

The Vortec Dual-Action PAC utilizes a standard 1/4” Industrial 
Interchange quick connect fitting to allow for easy attachment to existing 
filtered compressed air lines.
The Dual Action PAC can be used to provide a chilled air supply or a 
heated air supply to the user. Hot air exits from one end of the Dual 
Action PAC and cold air exits from the opposite end. These connections 
are ¾” male garden hose threads. The temperatures of the air streams 
can be adjusted slightly by changing the compressed air pressure to 
the Dual Action PAC. 
The Dual Action PAC can supply chilled or heated air to one of Vortec’s 
Diffuse Air Vests (Models 855, 857 or 859, purchased separately) or 
to a hood or helmet. The belt is attached to the Dual Action PAC for 
horizontal orientation but can be easily repositioned to allow for vertical 
orientation when used with a hood or helmet if desired.

maintenance

The Dual Action PAC may be disassembled for cleaning. When replacing 
the cold cap on the Dual Action PAC it is important to torque the cold 
cap to 100 inch pounds. For best results, use only clean filtered air.

1.  Do not operate a Dual Action Personal Air Conditioner at air 

pressures above 150 psig (10.3 bar).

2.  Do not operate a Dual Action Personal Air Conditioner at line 

temperatures above 110

o

F (43

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.

LimiteD warranty

Vortec compressed air products manufactured by ITW Air Management 
will be replaced or repaired if found to be defective due to manufacture 
defect within ten years from the date of invoice.  Diffuse Air Vests are 
not covered by this warranty if the vest has been removed from the 
packaging and placed into service.

 for full warranty details 

and limitations. ITW Air Management makes no specific warranty 
merchantability or warrant of fitness to a particular purpose.

Insufficient airflow may be caused by the following:
1.   Undersized compressed air supply size.
2.   Compressed air pressure too low.
3.   Insufficient compressed air volume (SCFM, SLPM).
4.  Partial or complete blockage of internal compressed air path, due to 

dirt.

5.   Loose cold cap (if disassembled for cleaning).
If trouble persists, please contact Vortec at 1-800-441-7475.

trOubLeShOOting

The compressed air supply must be filtered (5 micron maximum) to 
remove water and dirt. If oil is present in the compressed air supply, 
remove the oil using a .01 micron (maximum) coalescing filter. Filter 
recommendations are given in Table 1. Model 29625 consumes 25 
scfm (708 slpm) of air at 100 psig (6.9 bar) and Model 29635 consumes 
35 scfm (991 slpm) of air at 100 psig (6.9 bar).
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.

intrODuctiOn

The Vortec Dual Action Personal Air Conditioner (Dual Action PAC) and 
Diffuse Air Vest are designed to be used together to provide worker 
comfort in extreme temperatures. The vortex tube technology utilized in 
the Dual Action Personal Air Conditioner uses filtered, compressed air 
to concentrate chilled or heated air on the worker’s torso through the 
Diffuse Air Vest. With no moving parts, and under reasonable care, the 
Dual Action PAC and Diffuse Air Vest will provide years of trouble-free 
operation.

When using the cold air output from the Dual Action PAC, screw the 
black exhaust muffler onto the hot end of the unit. When using the hot 
air output, move the black exhaust muffler to the cold end. (Refer to the 
labeling on the unit.) Connect the non-muffled end to the vest or hood/
helmet via the ¾” male garden hose thread connection. The body of the 
Dual-Action PAC can be rotated 180 degrees to allow the compressed 
air inlet quick connect fitting to point in the most convenient direction 
(pointing down if the air supply hose is laying on the floor or pointing 
upward if the air supply hose is suspended from the ceiling).

Diffuse air Vest:

Upon receipt, inspect the vest and contact your Vortec representative 
immediately if you suspect damage of any kind to the vest. 

Once 

the vest is placed into service, it may not be returned under any 
circumstances.

 Put the vest on and secure at the front using the Velcro 

closure fasteners. Be sure to leave enough room to comfortably move 
in the vest. Securely attach the flexible hose on the back of the vest to 
the Dual Action PAC. Adjust the belt supplied with the Dual Action PAC 
to fit securely around the outside of the vest, and still allow comfortable 
movement to the wearer.
The ensure efficient operation, keep the Velcro neck flaps closed 
if using Model 29625. If using Model 29635, the neck flaps may be 
opened to provide cooling to the head and neck of the wearer.

The Dual Action PAC and Diffuse Air Vest may be used under welding 
leathers, coveralls and other protective garments, but the warm or 
cold air exhausted from the Dual Air PAC must be vented outside the 
garment.
