Odor Control
Overview
ClearAir Units are available with two types of odor control, a media bed type or a spray odor control.
There are two types of media beds, one is called the Loose Fill type and the other is called the Media Panel
type. The odor control media utilizes a blend of 50% potassium permanganate and 50% activated carbon.
The media is housed in either Odor Control Modules as shown in Figure 5-5-1 or compressed in Media
Panels as shown in Figure 5-4-1. As the air is drawn through the media the potassium permanganate
oxidizes the lighter odor molecules and chemically changes them into harmless solids which remain in
the media, and the carbon absorbs the heavier odor molecules.
ClearAir Units that include media bed odor control have a suffix in the model number of “SO” for single
pass, “DO” suffix for double pass and “TO” for triple pass odor control. ClearAir that utilize spray odor
control have a suffix SPO in the model number. Refer to the Nameplate on the unit (Refer Appendix D
page D-1 for a sample Nameplate).
The life of the odor control media is dependent upon several factors such as the type of odor, amount of
odor molecules, grease loading and the exhaust air temperature. The potassium permanganate media
has a flat efficiency curve, meaning that the efficiency, or effectiveness, stays constant until the media
has expended and then the efficiency drops off rapidly. The carbon portion of the media’s efficiency
drops continually during its life. Thus a regular schedule of change out of odor control media needs to be
established and followed.
Media Panel Type Odor Control
With the Media Panel type the odor control, the media is compressed into 18” x 24” x 1.25” Media
Panels which slide into a Module (Refer Figure5-4-1). The Modules then slide into the ClearAir racks.
As an option the unit may be equipped with a 30% pleated media After Filter located immediately
downstream of the Media Models.
Loose Fill Type Odor Control
The Loose Fill type the odor control media is housed in steel reusable Media Modules that can be
replenished with Loose Fill media (refer to Figure 5-5-1). With Loose Fill media a 30% pleated media
After Filter located immediately downstream of the Media Models is required.
