2.2 System Description
The air cleaner is a self-contained unit with a fan, a pre-filter section, final filter section, (a HEPA
filter section,) and LED indicator lights to identify power on and filter change time. These indicator
lights are shown below.
The “Power On” indicator light illuminates as soon as power is energized to the system. The red
“Change Filter” indicator light illuminates once the pressure drop of the filters has exceeded the
recommended pressure. This indicates the filters are “dirty” and need to be replaced with new
filters.
The unit enclosure is constructed from 16-gauge powder-coated steel. The pre-filter and final filter
access is from the air intake end of the unit and includes an integral filter holding frame that enables
filters to be installed without using fasteners.
The unit accommodates a 2-inch or 4-inch prefilter. The second stage accommodates a specific
HVAC air filter. The third stage includes a HEPA filter holding frame for the HEPA air filter.
The fan is positioned at the air exit side of the unit and has a rated capacity of up to 4000 cfm
(6800m3/hr) with air filters installed.
An air supply register with adjustable directional louvers is built into the air exit side of the unit.
Main Features
The unit has a full-size air intake
that draws fumes and other contaminants from the room. This air
is then filtered through each stage and re-circulated back into the conditioned space.
