AirQ 1280 5 About AirQ 1280
About AirQ 1280
Welcome to a whole new world of air treatment from Prolitec, the technology leader in air care with
scent. The AirQ 1280 appliance is the most advanced commercial air-treatment system on the market
today. It is the world’s rst fully adjustable commercial air-treatment system engineered to serve
indoor spaces.
AirQ 1280 is a patented, computer-controlled, always-on system capable of maintaining a constant,
uniform and controlled level of scent or odor neutralizer.
The AirQ 1280 converts fragrances and odor control formulations (“Agents”) into ultra-ne droplets
for controlled distribution as an aerosol or vapor directly into a room or via the airow of the HVAC
system, either through the central fan unit (CFU) or at suitable locations in the branched ductwork. It
is designed for permanent installation on a wall in the area to be treated or integrated with the CFU.
The AirQ 1280 is managed by an on-board computer that is fully adjustable, enabling intensity
settings to match space sizes from 1,800 to 150,000 cubic feet (50-4,200 cubic meters) per appliance.
The AirQ 1280 is programmable, capable of executing 21 distinct start and stop times, repeatable
daily or weekly. Utilizing up to 21 programs and the full range of 50 intensity settings allows you to
optimize the fragrance levels depending on peak and non-peak occupancy in the space. This new
feature can save you money on fragrance AND service visits. Multiple appliances can work together
on the same or multiple CFUs to treat the air in the same spaces served by the HVAC. Multiple
appliances can work together in the same space.
Typical AirQ 1280 applications include air treatment to enhance or improve indoor air quality
including odor cancelling, and ambient scenting in public spaces such as casinos, malls, hotels,
theaters, ballrooms, convention centers, hospitals, retirement and assisted living facilities, schools
and restrooms. A single AirQ 1280 can do both odor control and ambient scenting at the same time.
The AirQ 1280 with Prolitec odor control formulations and fragrances will cancel a wide range of
offensive odors and replace them with pleasant scents available from the Prolitec fragrance catalog
or custom developed to meet client requirements.
The AirQ 1280 works by generating ultra ne, ultra-light droplets approximately 1 micrometer (µm)
in diameter. By comparison, a droplet from a typical pressurized aerosol spray can is 50 microns
(50000 nanometers) in diameter or 50 times larger than an AirQ 1280 droplet. In terms of weight
and volume of liquid, the comparison is even more dramatic. A 50-micron aerosol droplet is 125,000
times heavier than a 1 µm AirQ droplet.1 (See also Table 1 below.) This tiny AirQ droplet offers many
performance benets over a conventional aerosol including: completely uniform distribution of the
treatment agent; 50 times more exposed surface area; and the absence of any liquid deposits on
surfaces such as the interior surfaces in an HVAC system.
AirQ 1280 is simple to install and program for specic room size, airow conditions, and desired
scent intensity. Minimal maintenance is required beyond the periodic change of the disposable
fragrance cartridge, inspection and annual replacement of three O-rings, and a simple wipe down or
dusting of exterior surfaces. Once installed in the right location, AirQ 1280 will outperform any other
system, providing completely uniform scent distribution.
The AirQ 1280’s advanced technology creates a scent effect with a smaller quantity of fragrance
ingredients than any other method. The chemicals employed in making AirQ 1280 fragrances are
fully compliant with the most restrictive air-quality and inhalation standards. AirQ 1280 generates no

AirQ 1280 6 About AirQ 1280
harmful VOCs and uses no ethanol or propellants. Quite simply, used as directed, AirQ 1280 is the
greenest, most eco- friendly way to introduce scent into an interior space with no negative impact on
indoor air quality. This is not an accident. The scientists and engineers at Prolitec are committed to
the highest ecological and human safety standards.
This user guide is easy to read. It is also important to read. AirQ 1280 is a high-performance
appliance that, installed and used correctly, will meet the most demanding requirements.

AirQ 1280 16 OPERATING INSTRUCTIONS
Setting Scent Intensity
1. Determine the approximate size of the room in cubic feet or cubic meters by multiplying length
x width x ceiling height.
2. Consult the Room-Size Table to give you a level (1 to 50) to set. THIS IS ONLY A STARTING
POINT.
Hint: There are many variables to nding the scent level that works:
size, airow, number of fresh air changes per hour, number of people in
the space and, most of all, user preferences. Experiment with different
levels until you are satised. Utilize the S4 Tool.
Scent Control
If you followed the Room-Size Table or S4 Tool, you have set AirQ 1280 to the low end of the range
for your room size. If after one hour you feel the scent is not detectable, increase the setting by
about 10%. For example, if your start setting was 20, increase it by 10%, or to setting 22. Keep
increasing until you and others in the space can detect a slight scent throughout the space.
The Last Step
1. Set the appliance to either 24/7 or RUN PROGRAM.
2. Make sure the power is on.
3. Close and lock the door, storing the key in a known place.

HVAC Pre-installation Checklist
This checklist should be completed before the install date.
1. Conrm the area to be targeted for air treatment.
2. Determine the Air Handling Unit or duct that serves the target area.
3. Make sure the AHU does not use an open gas ame.
4. Find and mark the optimal insertion point for the Injector Tube. (See “Appliance Positioning”)
5. Find and mark the exact location for placement of the appliance. (See “Appliance Positioning”)
6. Note the distance between the insertion point and the proposed appliance location. (NEVER
MORE THAN 3 FEET and there should NEVER be a LOW POINT in the hose run.)
7. Determine and mark the location for the 110 or 220V AC power outlet (NEVER DIRECTLY
BELOW THE appliance).
Appliance Positioning
It is important to nd an insertion point where the plume output will be smoothly drawn into and
mixed with the airow. On larger AHU’s it may be practical to mount the whole appliance inside the
AHU.
Best practice when installing in an AHU is to place the injector tube after the heating and cooling coils.
If this is not possible, the Plume 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 Prolitec Technical Support.
The best location for the Appliance is below the injector tube (Fig. A). The injector hose should be
run upward as short a distance as possible and NEVER MORE THAN 3 FEET. If an upward injector
hose run is not possible, care should be taken support the hose to prevent sagging or any low spot
in the run to avoid any possibility of condensation and liquid collection which will block the plume
output. The injector hose is prone to stretching, so support points should be placed every 6 inches
on horizontal runs. Give the hose a slight upward slant along its run (See Fig. B). The hose must not
be run horizontally. A strong tape (such as Venture tape) may be used to support short runs. The
hose may be run through PVC pipe for longer distances.
