(869 Pa) of static pressure.

• Permanent washable aluminum filters result in
many years of reliable use.

• Performance as cataloged is assured. All fan
sizes have been tested in an AMCA Accredited
Laboratory and are licensed to bear the AMCA
Sound and Air Performance Seal.

• Fan components are subjected to extensive life

Roof Curbs

Prefabricated roof curbs reduce installation time
and costs by ensuring compatibility between
the fan, the curb and roof opening. All curbs
are insulated. A wide variety of
roof curbs are available,
including: flanged,
pitched and sound­absorbing.

Curb Extension

Extensions raise the fan discharge above the roof
line and provide an accessible mounting location
for dampers. Insect screen bases, constructed
with a removable
fine mesh, are
recommended for
applications where
insect entry must
be prevented.

Curb Seal

Rubber seal between fan and curb is available to
ensure proper sealing when attached to a curb.

Disconnect Switches

A wide selection of
NEMA rated switches
are available for positive
electrical shutoff and
safety, including: general,
dust-tight, rainproof
and corrosion-resistant.
Optional switches ship
loose with unit.

Duct Adapters

Duct adapters fit over the roof curb and support the
top of the duct allowing ductwork
to be completed before the fan
is set in place. Duct adapters
also limit performance
losses by directing
airflow into
the duct.

Dampers

Designed to prevent outside air from entering back
into the building when fan is off. Flangeless intake
dampers are designed for horizontal mounting
inside ductwork. Includes
either gravity or motorized
dampers. Damper sizes
are shown on each
performance data page.

Typical Installation

Prepunched mounting holes and 21⁄2 inch skirt to
aid in installation

Supply Air Fan

This drawing shows
a typical commercial
kitchen ventilation
system that consists
of a roof mounted
upblast exhaust fan
and a supply fan.

Exhaust fan variations
include sidewall exhaust
fan (also shown) when
penetrating the roof is not
practical. A utility blower is
recommended when higher
static pressure capability
is required to pull exhaust
through long duct runs
(typically 3 stories or more).

Fan Sizing

Exhaust

When not specified by local codes,
the following guidelines may be used
to determine the minimum kitchen hood exhaust cfm.
Some local codes require 100 cfm/ft2 of hood area for
wall style hoods.

Supply

Recommended supply airflow is 90%
of exhaust cfm. The remaining 10%
of supply air will be drawn from areas
adjacent to the kitchen, which helps
prevent undesirable kitchen odors
from drifting into areas such as the
dining room.

Duty Level Type of Cooking Equipment cfm/ft2 of Hood

Light Oven, Range, Kettle 50

Medium Fryer, Griddle 75

Heavy Charbroiler, Electric Broiler 100

Static pressure typically ranges from 0.625 to 1.0 in. for one story buildings.

NFPA Considerations

The National Fire Protection Association specifies
minimum distance criteria for restaurant exhaust and
supply fans:

Option A

1. Roof deck to top of exhaust fan windband:
40 inches (1016 mm) minimum

2. Roof deck to top of curb:
18 inches (457 mm) minimum

3. Supply fan intake:
10 feet (3048 mm) minimum from all exhaust fans

40 in. min.

(1016 mm min.)

18 in. min.

(457 mm min.)

Cooking
Equipment

Option A

10 ft. min.

(3 m min.)

36 in. min.

Option B

For applications where the 10 feet (3048 mm) horizontal distance
cannot be met, vertical separation between exhaust and supply
must be at least 36 inches (914 mm).

Option B

12 in.

(305 mm)

Service

Filtered supply fans require regular inspection and
cleaning (or replacement) of filters to ensure high
efficiency and performance. The model SAF is
designed to provide easy access to filters and
other components through a convenient removable
hood cover.

Removable Hood Cover

Removal of the hood cover allows easy access to all
fan components for inspection, cleaning, and service.

Serviceability

The internal drive components are easy to reach
and service with the hood removed.

Weather Resistant Fasteners

Easy to remove galvanized fasteners keep the
hood cover secured.

Filter Removal

Filter racks are designed so filters can easily slide out
for cleaning or replacement.

Model Number Code

The model number system is designed to completely identify the fan. The correct code letters must be
specified to designate belt or direct drive. The remainder of the model number is determined by the size
and performance selected from the following pages.
