TECHNOLOGY
The Air Stream Duo uses nebulization (cold-air diffusion) to diffuse our aroma oil blends.
This is a process that breaks down the oils into a very fine, dry mist. Nebulization preserves
the intention and integrity behind our oils while maximizing their olfactive and therapeutic
powers, without diluting in water, solvent, or using heat.
This patented nebulizing technology, combined with our commercial fragrance oil
blends, produces nanoparticles that suspend in the air for several hours creating a clean
and consistent ambient scent, without chemical undertones.
Commercial fragrance diffusers help to create an emotional connection with consumers
by creating lasting impressions, memories, and multi-sensory responses. At the same
time they increase energy, inspire brand loyalty, improve sales, mask unpleasant odors,
reduce dust, pet dander allergens, and other airborne allergens from non-living matter.
Cold-air diffusers support healthy indoor air quality while providing ambience and
well-being for you, your employees, and clientele.
Diffusing helps to reduce dust, pet dander allergens, and other airborne allergens from
non-living matter (e.g. dust mite matter allergens). While AromaTech’s 100% all natural
diffuser blends bring nature’s goodness into your space by supporting harmony and
balance.
Using only AromaTech essential and aroma oil blends will guarantee the best
performance of your diffuser. No mixing or diluting with water, carrier oils or alcohol is
required. Simply fill the bottle with what nature created and enjoy!

WHERE TO PLACE THE DIFFUSER
Applications: aromatherapy, ambient scenting and odor control in home or business.
Location: The Air Stream line is designed to scent spaces from 1,000 square feet and up. By
discretely connecting to your ventilation system, this HVAC scent machine covers medium
to large size spaces such as hotel lobbies, guest corridors, retail floor, gyms, conference
rooms, homes and much more.
Scenting Coverage: Air Stream Duo can be adjusted to scent an area ranging from 1000
sq.ft. to 15,000 sq.ft. (100 to 1500 sq.m)
Scent Intensity: Adjust your scenting experience and hours of operation through the
internal touch LCD timer.
Device Location: The most important element of your scenting experience is to properly
position the device in the room, to ensure optimal performance and control.
Below are our suggestions
• Choose a location where the aroma oil molecules can use the natural airflow in a room.
This is particularly important with air-conditioned spaces. The best location for the
Air Stream Duo is where there is a lot of airflow.
• If you are not sure of the direction of the airflow, simply turn on the Air Stream Single and
using a flashlight, point it at the scent output and watch where the scent travels.
Alternatively, light a match and blow it out immediately. The direction of the scent or
smoke will tell you which way the fragrance will travel.

HVAC INSTALLATION
HVAC Pre-installation Checklist
Please complete this checklist before installing the scent diffuser
1. Plan the area to be scented.
2. Locate the Air Handling Unit or duct that serves the area to be scented.
3. Make sure the Air Handling Unit does not use an open gas flame.
4. Locate and mark the optimal position for the Scent Point.
(See Figure A page 13)
5. Locate and mark the exact location for placement of the scent diffuser.
(See Figure A page 13)
6. Confirm the distance between the Scent Point and the proposed scent diffuser
location. (Air tube should be max.3 feet. Avoid dips and coils or lows in the air tube.
The Scent Point should ALWAYS be higher than the scent diffuser.)
7. Locate and install 110V or 220V AC power outlet close to the diffuser installation
location. Avoid placing the power outlet directly under the scent diffuser.
Scent Diffuser Positioning
It is important to locate an insertion point where the scent output will be smoothly drawn
into and mixed with the airflow. This usually means those parts of the AHU where the
static pressure is negative.
Ideal locations:
• In front of the supply fan with injection through the wall of the AHU. Position
immediately before the fan and after the coils if possible, or in the mixed air chamber.
• Behind the blower with the entire scent diffuser mounted inside the AHU in the mixed
air chamber.
• Outside the AHU in the Supply Air duct.

Air Tube Connection on Air Duct
CORRECT CORRECT
INCORRECT
Tube has a pocket, this part
will fill up with oil.
pocket
Best practice when installing in an AHU is to place the hose guide after the heating and
cooling coils. If this is not possible, the scent output can pass over hot water, steam,
chilled water, and DX coils.
Open gas flames should absolutely be avoided. If installation must be over gas
heated coils or open gas flames, contact AromaTech Technical Support.
The best location for the Scent Machine is below the Scent Point. The air tube should run
upward as short a distance as possible, and NEVER MORE THAN 3 FEET. If an upward air
tube run is not possible, care should be taken to support the hose to prevent sagging or
any low spots. This is to avoid any possibility of condensation and liquid collection which
will block the scent output. Give the air tube an upward slant along its run
(See image below)

Connecting the Diffuser to HVAC.
Refer to the Air Stream Duo HVAC Connection Diagram FIG A.
The Air Stream Duo is a versatile and powerful commercial HVAC system scent diffuser.
Diffusing the scent via HVAC will allow you to cover multiple rooms and zones. To scent the
right zones, check with your HVAC provider or Mechanical Engineer to determine which
HVAC unit to connect to.
The Air Stream Duo can cover 15,000 sq.ft. of space.
1. You need to choose the air handler you want to connect to. If you have multiple air
handlers, select the one that will cover the area you wish to be scented. Consult your
HVAC supplier if needed.
2. With a metal drill bit designed to drill through sheet metal, drill a 7/8-inch hole in the air
duct directly after the blower. Make sure you are tapping into the supply side of your
duct, not the return side.
3. IMPORTANT: Never install before the coils or filters as the filters will dilute the scent
and you will not get the same result.
4. Once the 7/8-inch hole is made, insert the hose guide. The hole on the end of the hose
guide should be pointing with the air flow not against it. This allows the scent to travel
in the same direction as the air flow.
5. Secure the hose guide by screwing it to the duct.
6. Screw the supplied HVAC adaptor into the hose guide.
7. Take a second HVAC adaptor and screw it into the Air Stream Duo.
8. Either wall mount the Air Stream Duo to the duct, the wall or place on a shelf directly
under the Scent Point connection. It’s important to keep the Air Stream Duo as close as
possible to the scent point. MAX. AIR TUBE LENGTH SHOULD BE 3 FEET.
9. Cut supplied air tube to the correct length to go from the Air Stream diffuser.
The distance between the Air Stream diffuser and air tube should be as short as possible.
MAX. 3 FEET. Do not leave any slack. Coiling or excess air tube will create air
pockets and buildup of scent inside the tube.
10. Connect the AirStream Duo to the 110V-240V plug and set the timer.

Recommended Intensity Settings.
The grading system starts from 1 being the lowest and ends with 20 being the highest.
Short but frequent bursts are recommended. Using the lower settings will allow for a
subtler scenting experience without being over powering. Intensity setting is personal and
depends on multiple factors, such as air flow, the location of the scent machine and how
subtle or strong you want the scent to be. Use your discretion and start at Grade 1 and
work your way up if needed.
To test if the intensity is too strong or too light, leave the scented area for at least
5 minutes and re-enter after getting some fresh air. Only then will you be able to tell if the
intensity grade needs to be adjusted up or down.
Please note that the human nose gets used to a fragrance after 30 minutes of exposure. If
at any point during the diffusion process you don't smell the scent any more simply leave
the scented area and re-enter after getting some fresh air.
