Greenheck’s series KSF is available in a belt drive
(KSFB) and direct drive (KSFD). Both have a compact
design providing untempered make-up air for
commercial and institutional kitchen applications.
Eight available blower sizes provide airflow
capacities up to 10,500 cfm and static pressure
capabilities up to 2.0 in. wg.
Installation may be stand alone or on a combination
curb with exhaust fan. See page 3 for details.
Features
Weatherhood and Filters
A weatherhood is standard and meets NFPA 96
requirements when used with a combination package.
See page 3 for details. All weatherhoods come
standard with UL Class 2 rated, 1 in. washable
aluminum mesh filters.
Vibration Isolators
The motor and wheel assembly is
mounted on vibration isolators to
minimize noise transmission into the
building.
Accessories
Kitchen Fan Control Center (KFCC)
Prewired in compliance to the National
Electrical Code, the KFCC simplifies
field wiring, thereby reducing
installation time and mistakes. The
control center is a UL Listed NEMA 1
panel for mounting indoors. It is
designed to interlock with the fir
suppression system.
Remote Starter Control Panel (RSCP)
The Remote Starter Control Panel (RSCP) offers
safety and reliability for remote operation of up to
four fans. Standard NEMA 3R housing allows panel to
be mounted outdoors.

With either ten feet of horizontal separation or three
feet of vertical separation, Greenheck has a
combination package for your requirements. The
Greenheck combination package simplifies
installation and reduces field labor costs. This preengineered design offers the benefit of only one roof
penetration for both supply and exhaust ducts, while
ensuring complete compatibility and interface
between the supply fan, exhaust fan, curb and
combination extension.
3 Ft. Vertical Separation - Short Weatherhood
Greenheck combination packages are specifically
designed to comply with NFPA 96, which states:
• Exhaust duct must terminate at least 24 in. above
the roof deck.
• Fan discharge must terminate at least 40 in. above
the roof deck.
• There must be at least 10 ft. of horizontal or 3 ft. of
vertical separation between the intake and exhaust
discharge.
Provides 3 ft. of vertical
separation for
compliance to NFP
A 96.
