F116 SERIES 2 SELF-CONTAINED DUCTABLE COMMERCIAL AIR CLEANER
20. Replace the motor compartment cover.
Because the F116 Series 2 air cleaner provides its own
circulation, it can be mounted independently or in a duct
system. When used in a duct, the air cleaner volume must
be the same as the duct and plenum.
When the air cleaner is powered, the blower/motor draws
the contaminated air into the air cleaner. Particles that are
too small to be caught in the prefilter are trapped by the
primary filter. The clean air is then discharged (two stage)
or goes through a second primary filter (three stage) and
is then discharged.
The F116 Series 2 air cleaner has been engineered to
improve indoor air quality for commercial and industrial
applications. The filters are the most practical and
effective filtering system for removing atmospheric dust,
pollens, bacteria, viruses, mold spores, smoke, fumes,
mists and aerosols. Refer to Fig. 8.
The air cleaner is either operating or off. There are no other
operational options available. Even when the area is
unoccupied, the air cleaner can be operated continuously
to prevent buildup of airborne contaminants. Operate the
air cleaner only when the area is occupied when specific
activities produce contaminants.
The CPZ™ sorbent module has the ability to collect and
hold gas-phase compounds and vapors typically found in
commercial and light industrial facilities. These gases and
vapors frequently appear as odors that, at times, can be
annoying and irritating. The modules become saturated
after collecting 25% to 50% of their weight in gaseous
odors. The quantity of CPZ™ material provides adequate
dwell time to ensure up to 95% collection efficiency in the
first pass. This also provides a long maintenance-free
The minimum recommended air exchange rate is 2.5
times per hour. In a heavily contaminated area, up to 15 air
exchanges per hour can be necessary. The factors that
determine what the rate of air exchange should be are:
• generation rates of the various pollutants;
• concentration level of the pollutants;
• desired contamination reduction level.
Airborne contaminants will always be present in the air
where contaminant generations take place. Air cleaning
systems and ventilators do not eliminate airborne
contaminants, they reduce the excessive accumulation of
the contaminants. To eliminate the contamination, the
source of contamination must be removed.
Local, Federal and professional ventilation engineering
standards and codes prescribe minimum ventilation rates
to dilute air contamination in specific applications. The
ventilation rates usually assume the injection of outdoor
air measured as air exchange rate. The use of the F116 air
cleaner to comply with ventilation requirements is an
acceptable alternative to ventilation with outdoor air.
However, at least 20% of a specified ventilation rate or
code must be derived from outdoor air. The F116 air
cleaner filtered and recirculated air can be the remaining
Can cause personal injury or equipment damage.
Turn off power before installing or servicing the air
Be sure to change filters as recommended to pre-
vent reduced airflow in the air cleaner. Stand on a
stable platform when working with the air cleaner.
Air cleaner and components are susceptible to
damage. Take care when working with them to
avoid equipment damage.
The air cleaner removes a variety of particulate
contaminants from the air. In the process of cleaning the
air, the air cleaner filters become dirty and the cleaning
efficiency is lowered.
To maintain a high standard of reliability and efficiency, it
is necessary to periodically service the air cleaner. The
maintenance is determined by the quantity and type of
contaminants present and the frequency of air cleaner
use. The frequency of servicing can be established after a
period of use.
NOTE: Some full-service distributors provide regular
servicing to commercial establishments.
The particle filter life ranges from 6 to 24 months with 12
to 18 months as an average.The useful life of the CPZ™
sorbent modules may vary from 4 to 24 months,
depending on the application. In most applications, the
sorbent media life ranges from 4 to12 months. The filters
and modules need to be changed more frequently in
facilities that operate 24 hours a day.
Determining Media Filter Change
Media type particulate filters cause an increase in
pressure as they collect and retain airborne particulates.
The best way to determine when to replace these filters
involves monitoring the pressure across the filters with a
differential pressure gauge.
If a differential pressure gauge is not used, the apparent
air volume that one feels is a good indicator of the filter
loading. When the air volume is noticeably less, the
cleanliness of the air in the space will decline. When that
occurs, change the primary media filter(s). Then schedule
the next primary media filter(s) change to occur 60 days
earlier that the first filter change. Typically, change the
prefilter at least every 3 months and the primary media
filter(s) 12 to 18 months.
CPZ™ Adsorbent Module
The CPZ™ adsorbent module is used to collect gases,
vapors, odors and volatile organic compounds (V.O.C.)
from the air that passes through the air cleaner.
Adsorbents collect and hold 25% to 50% of their weight in
odorous gases and vapors. The impurities are collected
