2. PLANNING YOUR INSTALLATION
Selecting the Correct AirMaid
Choose the AirMaid model from the following table based upon the total duct airflow for the application. If the duct has
several branches, equip each branch with the correctly sized model for its airflow. In this way we maintain a consistent
concentration of ozone (typically from 0.5 to 1.0 ppm) throughout all sections of the duct system. For larger airflows,
simply install several units in parallel. For restaurants with a higher than average grease or odor discharge, please consult
with your nearest AirMaid sales representative for recommendations for your specific application.

Inlet Air Supply (Bleed Air): Adjust to the "Target Bleed Airflow" when able
Filtered Air. The air supplied and bled through the AirMaid generator is the “fuel“ to create its ozone and must be filtered.
To minimize equipment maintenance, use an air source with the least pollutants. Inlet air is preferred taken from a filtered
central ventilation or MUA supply. If this is not possible, then a filter box satisfying at least class MERV5/EU3 shall be in-
stalled. Filter box inlet air can be taken from above an inner ceiling, from an adjoining space, or from the outdoors with
precautions taken to prevent the entry of moisture. If taken from the outdoors, never position the inlet in the vicinity of the
discharge from any ventilation system which commonly contain moisture and pollutants. If air must be taken from inside a
kitchen space, please position the intake the farthest distance possible from preparation or cooking areas. The temperature
of the inlet air shall never exceed 104°F.
Bleed Airflow. With the extraction fan running the airflow through each inlet pipe must always fall within the specification:
45–85 cfm per inlet pipe (Models 10000V and 20000V), 30–50 cfm (Models 2000V and 5000V).
When used in conjunction with VAV/VSD systems, if the total Bleed Airflow through the AirMaid generator drops below
the minimum specification at the lowest extraction fan speed then power to AirMaid must then be cut off.

When used in conjunction with VAV/VSD systems, the Static Pressure must fall within specifications even at the lowest
