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.

Commercial Kitchen Ventilation

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.
