units with four or eight-foot
blank section, as well as
steam and hot water units
with eight-foot blank section,
unit casing only.
Twelve-inch deep cartridge filter shall
be U.L. Class 2 and mounted with a
rigid 7/8” nominal thickness header
frame. These cartridge filters shall
have an efficiency rating of MERV 14

Temperature Rated, Cartridge,
Final Filter Option
Note: Available on gas and electric
heat units with eight-foot
blank section casing only.
Twelve-inch deep cartridge filters
shall be U.L. Class 1 and be mounted
in a galvanized steel casing with a
7/8” nominal thickness header frame.
These cartridge filters shall have an
efficiency rating of MERV 14 per
ASHRAE 52.2. To ensure maximum
cartridge final filter life high
temperature rated two-inch prefilters
shall be included with the cartridge
filters. Filters shall be mounted in a
galvanized steel filter frame bank.

Exhaust Air
General
Exhaust air options shall include no
relief, 100 percent modulating
exhaust fan and 100 percent
modulating exhaust fan with direct
space building pressurization control.
Exhaust fans shall be either standard
or low airflow
No Relief (Standard)
Relief air opening shall be sealed
with panel and made watertight.
100 Percent Modulating Exhaust
Fan Option
Fan design shall be double width,
double inlet forward-curved type. Fan
shall be mounted on a shaft with
fixed sheave drive. All fans shall be
dynamically balanced and tested in
factory before being installed in unit.
It shall be test run in unit as part of
unit test. Fan operating envelop rpm
shall be below first critical speed. Fan
shaft shall be mounted on two grease
lubricated ball or roller bearings as
applicable designed for 200000-hour
average life. Extended grease lines
shall be provided to allow greasing of
bearings from section base rail.
Fan motor and assembly shall be
mounted on common base to allow
consistent belt tension with no
relative motion between fan and
motor shafts. The entire assembly
shall be completely isolated from
unit with 2-inch spring isolation.
Discharge dampers at unit outlet
shall modulate exhaust airflow in
response to OA damper position.
100 Percent Modulating Exhaust
Fan with Statitrac™ Control
Option
Fan design shall be double width,
double inlet forward-curved type. Fan
shall be mounted on a shaft with
fixed sheave drive. All fans shall be
dynamically balanced and tested in
factory before being installed in unit.
Exhaust fan shall be test run as part
of unit final run test. Fan operating
envelop rpm shall be below first
critical speed. Fan shaft shall be
mounted on two grease lubricated
ball or roller bearings designed for
200000-hour average life. Extended
grease lines shall be provided to
allow greasing of bearings from
section base rail.
Fan motor and assembly shall be
mounted on common base to allow
consistent belt tension with no
relative motion between fan and
motor shafts. The entire assembly
shall be completely isolated from
unit with 2-inch spring isolators. For
both CV and VAV air handlers, the
100 percent modulating exhaust
discharge damper (or VFD) shall be
modulated in response to building
pressure.
A differential pressure control
system, (Statitrac), shall use a
differential pressure transducer to
compare indoor building pressure to
outdoor ambient atmospheric
pressure. The FC exhaust fan shall be
turned on when required to lower
building static pressure setpoint. The
(Statitrac) control system shall then
modulate the discharge dampers (or
VFD) to control the building pressure
to within the adjustable, specified
deadband that shall be adjustable at
the Human Interface Panel.
