PRODUCT FEATURES

Make-Up Air Systems

GREENHECK

The Greenheck model KSF is designed to
provide untempered make-up air for
commercial and institutional kitchens. Seven
sizes of this model provide airflow capacities
up to 12,000 cfm and static pressure
capabilities up to 2.0 in. wg.

Installation may be stand alone or on a
combination curb with model CUBE exhaust
fan. See page 3 for details.

Durable Construction

Designed for maximum weather resistance,
KSF housings are constructed of heavy gauge
G90 galvanized steel. Lifting lugs are standard.

Weatherhood

Weatherhood is standard and includes washable 1in.
aluminum mesh filters. An extended weatherhood is
available to provide 10 feet of horizontal separation

from exhaust fan to meet code requirements.

Control Center (optional)

The control center includes the following standard
components:

• Magnetic motor starter with solid state overload
protection

• Control transformer with
fusing

• Integral door interlocking
disconnect switch

• Separately fused motor

• Distribution terminal strip

Premium grade control
components are selected for reliable operation. All
electrical components are UL Listed, recognized or
classified and factory prewired for single point
power connection.

Shafts

Shafts are precision turned, ground and polished
steel sized so that the first critical speed is at least

25% over the maximum operating speed.

Bearings

Shafts rotate in permanently lubricated, heavy duty
ball bearings. Bearings are selected for a minimum
average (L10) life in excess of 100,000 hours at

maximum operation speeds.

Vibration Isolators

The entire fan and motor
assembly is mounted on
vibration isolators to minimize
noise transmission into the

building.

Reliable Fan Performance

Air performance ratings from Greenheck’s AMCA
registered test chamber ensure accurate data.

Double width, double
inlet forward curved
wheels for high
efficiency and low sound
levels are constructed of
heavy gauge steel.
Wheels are statically and
dynamically balanced to
ensure vibration free
operation.

Access Panels

Large access panels are provided for easy
inspection and maintenance of motors, drives, fan
wheel, filters and controls.

Factory Wired
and Tested

All units are
tested prior to
shipment to
ensure proper
operation.

Provides 3 feet of vertical separation
for compliance to NFPA 96 (where
space limitations prevent 10 feet of
horizontal separation).

Model KSF has a compact design that is
available in both downblast discharge
(arrangement DB) and horizontal discharge
(arrangement HZ).

Installations may be as stand alone supply
fans as pictured at right or as combination
packages with exhaust and supply fans on
a common curb as shown below.

Provides 10 feet of horizontal separation
for compliance to NFPA 96.

Combination Packages

3 ft. Vertical Separation

The Greenheck combination package simplifies
installation and reduces field labor costs. The pre­engineered design ensures that the supply fan, exhaust
fan, curb and combination extension components
interface properly.

Equally important, Greenheck combination packages
are specifically designed to comply with NFPA 96.

NFPA 96 states:

• Exhaust duct must terminate at least 24 in. above the
roof deck

• Fan discharge must be at least 40 in. above the roof deck

• Air intake shall have a horizontal separation of 10 feet
from the exhaust discharge

Where space limitations absolutely prevent 10 feet of
horizontal separation from air intake, a vertical
separation will be acceptable. In this case, the exhaust
outlet must be a minimum of 3 feet above any air
intake located within 10 feet horizontally.

With either 10 feet of horizontal separation or 3 feet of
vertical separation, Greenheck has a combination
package for your requirements. See drawings below.

Note: Consult local codes and the authority having
jurisdiction if there are questions concerning the use of
this product.

See Greenheck’s Series C catalog for complete details
on the exhaust fan.

Control Centers

Prewired fan control centers contain magnetic motor
starters, control transformers, integral master
disconnect switch, fuse blocks and other required
components for power connection. The control center
is wired in conformance with the National Electric
Code.

Roof Curbs

Prefabricated roof curbs are available to reduce
installation time and costs by ensuring compatibility
between the fan and the roof opening. All curbs are
lined with fiberglass insulation to prevent condensation
and reduce sound levels. See Greenheck’s roof curb
catalog for complete details.

Duct Adapter

The duct adapter fits over the roof curb and supports
the top of the duct to allow ductwork to be completed
before the fan is set in place. Duct adapters also limit
performance losses by directing airflow into the
ductwork.

Filters

All units come standard with 1 in. washable aluminum
mesh filters. Optional 2 in. aluminum mesh filters are
available.

Dampers

Motorized discharge dampers are available in order to
prevent drafts into the building when the unit is not in
use. The damper is shipped loose and mounted
downstream in the ductwork. Arrangement DB with 10 ft.
horizontal separation is also available with a motorized
intake damper.

Extended Weatherhood

An extended weatherhood is available for stand alone
installations and is required for arrangement DBC.
