KITCHEN RANGE HOODS
1. CFM required is length x width (in feet) x velocity
as per above table.
(Depth of hood does not enter into calculations)
2. Hood should extend approximately 12 inches
beyond front and sides of range. Depth should
be two feet or more to accommodate bursts of
smoke.
3. Duct velocity can be 500 to 2000 FPM.
4. Two smaller ventilators are recommended in
place of one for more flexible operation and also
to provide ventilation should one fan fail.
Recommended ventilators for kitchen range
hoods are radial blade and backward curve
blowers.
5. U.L. classification YZHW and NFPA 96 provide
more detail.

Although fan noise is a function of a multitude of factors
the principal sources are (a) air turbulence (b) mechanical
and (c) vibration. Generally the quietest fan is also the most
mechanically efficient. Because a given fan location characteristics dictate audible noise, fan dBA cannot be guaranteed. However, relative noise levels of fans can be suitable
for considering one fan versus another.
The SONE number used in this catalog is a mathematically derived loudness (sound pressure) value as heard by
the human ear 5 feet from the inlet of the noise source in free
air (no ducts). Under these conditions, 10 SONES is twice as
loud as 5 SONES; or 20 SONES is 1/2 as loud as 40
SONES. Thus, SONE NUMBERS can be used as guides for
fan selection.
Where noise is a critical factor a more detailed, scientific analysis of the noise source and its surroundings would be
desirable. However, lined ducts, especially near the fan, provide ample sound attenuation for most clean air situations.
Also, to double the loudness (SONES) of a given fan, 13
more of the same fan must be added.

MOTOR INFORMATION
Central Fan Co. uses motors that comply with EPACT (see page 10)
Follow all local electrical and safety codes, as well as the National
Electrical Code (NEC) and the Occupational Safety and Health Act
(OSHA).
TYPE OF MOTOR USUALLY REQUIRED
The great majority of small motors (1⁄2 HP & smaller) are 115 volts
single phase.
NEMA MOTOR FRAME DIMENSIONS-INCHES
Sizes of 3⁄4 to 11⁄2 are fairly divided between 208/230 volts single
phase and 208 to 550 volts 3 phase.
Sizes of 2 HP and larger are generally three phase as they are less
expensive and less troublesome than single phase motors.

EFFECT OF VOLTAGE IMBALANCE
A small voltage imbalance between phases will cause an abnormal
temperature rise and abnormal current. For example, temperature &
current will rise 6-10 times the voltage difference. Notify the power company if voltage exceeds 1% (2 volts at 200v).

Caution:
Explosion Proof motors and non-sparking blades are usually
required in operating environments where explosive or ignitable
gases or dust are present. Proper motor selection requires full
understanding of U.L. and N.E.C. code designations. Article 500
(N.E.C.) covers the requirements for electrical equipment and
wiring. Equipment selection and wiring is a customer (user)
responsibility. Motors and impellers misapplied in hazardous environments are dangerous to personnel and property.
Examples of some hazardous materials:
Class I (Gases, Vapors)
Group AAcetylene.
Group BButadiene, ethylene oxide, hydrogen, propylene oxide.
Group CAcetaldehyde, cyclopropane, diethyl ether, ethylene,
isoprene.
Group DAcetone, acrylonitrile, ammonia, benzene, butane,
ethylene dichloride, gasoline, hexane, methane,
methanol, naphtha, propane, propylene, styrene,
toluene, vinyl acetate, vinyl chloride, xylene.
Note: A motor rated for Class I, Group D should not be used in the presence of Group A,B or C substances; and a Class II, Group F & G motor
should not be used with Group E substances.

3-wire control
for constant 115v
INPUT POWER SAVING (RPM CONTROL)
A significant reduction in energy consumption is realized when centrifugal fan
speeds are reduced only slightly. In applications where maximum demand volume
is not constant (VAV Systems), RPM control with inverters (variable frequency)
could result in considerable reduction in power consumption. (Fan power demand
varies with RPM3)
Analysis of each fan application will determine the suitability of various volume
control methods (Dampers, inlet vanes & inverters). Inverters available special order.
(X) Available
The Energy Policy Act (EPAct) took effect October 24, 1997. This law mandates efficiency standards for general purpose, three phase, 2,4 and 6 pole
AC motors from 1 to 200 horsepower manufactured for sale in the U.S. Many motors such as explosion proof, two speed, TEFC, single phase and others, are excluded. Central Fan will provide motors that comply with the mandate when applicable.

Residential Attic Fans
IMPORTANT FEATURES
Fan size selected should be capable of changing the entire volume of a
home in approximately two minutes. (Do not include the attic space unless
used for living .)
• Slow speed belt driven for quietness
• Ball bearing fan & motor-permanently lubricated
• Compact construction with no unnecessary weight
An average size home will require a 30 inch fan.
Operation with a time switch is recommended. Turn fan on for hours desired
and forget it. Fan shuts off automatically.
• Two types to choose from
• Single phase-115 Volts ODP
Time switch installs in single gang switch box. Two speed operation affords
additional flexibility. Two speed & timer switches in double gang box.
Atlas Wall Fans
Recommended for their quietness of operation. For attic window or wall installation in
homes with reasonably air tight attics. Two smaller fans may be used if space is not available for one large fan.
Fan installs against wall opening on the inside and the shutters on the outside. Shutters
close automatically when the fan stops, keeping rain, wind and insects out.
Ceiling opening may be used as an access to the attic if ceiling shutters are placed on
the attic floor unfastened.

DRAFT INDUCERS
FOR VERTICAL VENTING
[See page 14 for make-up (combustion) air devices.]
DRAFT INDUCER SELECTION TABLE
TJERNLUND AUTO-DRAFT INDUCERS
assure positive draft when restricted boilers and furnaces, poor chimneys or negative pressures in building prevent proper
exhaust of combustion gas. The Venturi
action of Tjernlund Auto-Draft Inducers
starts air moving up the stack instantly,
keeps it moving smoothly. These units are
adaptable to all heating systems. They are
quick and easy to install and completely
automatic in operation. Tjernlund's unique
design and careful construction makes
them trouble-free and reduces maintenance to a minimum. The Vari-Draft
Control permits adjustment to the individual
job requirement.

NOTE:
1. Inputs shown above are believed

2. Consideration is given to typically
higher static pressure requirements for larger installations, for
the type of fuel burned, and for
the type of draft control installed.
3. Where pressure requirements
are unknown, or believed to be

The T-Series range boasts features and a
specification that marks a radical departure
from current unit ventilation technology.
• Designer-styled
in two-tone grey to bring
slim sophisticated good looks to today's
commercial and residential environments.
• A Speed Control Pack which gives one of
three fixed speeds at the time of installation
without the need for a Controller. When set
on High, T-Series fans give a performance
which outclasses competitive products.
• Four sizes in each model, mean 12 performance options - so sizing is no longer a hit or
miss affair.
• An
advanced interlocking shutter system
effectively closing against backdraft — controlled by state-of-the-art electronics to
ensure quiet and reliable actuation whatever
the angle of installation. (exhaust or supply)
• A new system of mounting for Window
and
Roof models which accommodates varying
mounting thicknesses. Wall models have telescopic liners for all types of walls and a neat
decorative trim.
• For
cleaning, T-series units can be completely dismantled in minutes without the
need for special tools and all the non-electrical components can be washed thoroughly
in warm soapy water.

DIRECT DRIVE UTILITY BLOWERS
FORWARD CURVE WHEELS - SINGLE INLET - ARRANGEMENT 4
For general ventilation where duct systems are required. Compact, easy to mount and quiet in operation, these
blowers are designed to deliver large volumes of air economically. Ideal for wash rooms, boiler rooms, restaurants, and
small hood exhaust.
Note: Low static pressure systems may overload certain motors. Where this condition exists, increase the static pressure with duct work, dampers, etc.
CLOCKWISE ROTATION—Bottom horizontal discharge (as shown in photo) furnished unless otherwise specified.
DISCHARGE POSITION easily changed to any one of eight different positions. Rotation as viewed from the motor end.
(See page 31.)
Suitable for temperatures to 250°F. (500° with slinger)
Wheels are heavy gauge steel construction. Available with spark resistant aluminum wheels.

*When centrifugal fan outlet velocities exceed 2000 ft/min. shutters and other fittings should be located at least 21⁄2 duct diameters of straight duct
from the blower discharge. Unpredictable shutter performance will result if the shutter is on the blower discharge. Blower performance is enhanced by
a properly designed expander (evasé) mounted on the discharge. Shutters ( and other fittings) should be installed downstream of the evasé.
**See p. 38 for coatings and pp. 36 and 37 for PVC and FRP blowers. ‡See p. 29 for spark resistant construction. (X) Available accessories

Coatings Summary: (Central Fan will apply the following coatings.)
PVC-Sprayed, air dryed, multilayer coatings have good-to-excellent resistance to most acids, alkalies and marine exposures. Coatings are flexible,
fairly durable, and good to 150°F. The most commonly used protective coating. Unsuitable in most vapor phase organic solvents.
Eisenheiss-Synthetic polyester resin which is sprayed, air dryed in multilayer coatings providing tough impermeable coatings good to 150°F.
Chemical resistance similar to PVC except notably a slightly better performance when exposed to tricholorethylene, benzene, carbon tet., or gasoline. Does not perform well in hydrogen peroxide.
Heresite-A sprayed phenolic resin coating which provides good resistance to most common solvents, organic and inorganic acids. Not
recommended for caustics, alkalies, and oxidizing agents. Good to 120°F. Affords fair resistance to methyl ethyl ketone, methylene chloride,
trichlorethylene.
Epoxy-One of the most durable all-purpose coatings which withstands reasonable abrasion and most chemicals.
Baked epoxy-(Factory applied by Peerless on all blowers) effectively protects carbon steel surfaces from normal atmospheric conditions. Is attacked
by acids, alkalies, and certain solvents. Can provide effective undercoating. CENTRAL FAN DOES NOT APPLY BAKED EPOXY COATINGS.
NOTE: BECAUSE OF THE INHERENT FRAGILITY OF ALL COATINGS, NO EXPLICIT WARRANTY OF SERVICEABILITY CAN BE MADE.
BLOWERS: Rigid PVC has good all-around corrosion resistance and is usually the economic material of choice. However, PVC becomes brittle at sub-zero temperatures and loses its strength above 150°F. Thus, steel reinforcement is used in PVC blower wheels. Do not use FRP above 250°F, or PVDF above 180°F.
All are spark resistant (electric insulator). Graphite impregnation into FRP can make it conductive to control static electricity. UV radiation (direct sun) will
destroy polypropylene. Although slightly more in initial cost, FRP blowers prove to be more economical where the environment is severe and maximum durability is desired. Polyvinylidene (PVDF) will withstand inorganic acids and bases, organic acids, alcohols, aliphatic and aromatic hydrocarbons and halogenated solvents and halogens (except fluorine).

Isolators for Vibration and Noise Control
The most effective vibration and noise control is obtained when the isolator deflects up to its maximum limit…without exceeding that maximum deflection.
For proper selection:
1. Equipment weight - greater deflection (up to max.) provides maximum isolation
2. Equipment RPM - lower than 1200RPM use springs for maximum isolation (Higher RPM’s use rubber regardless of substructure)
3. Equipment Location(a)Rigid sub-structure-use rubber or springs
(b)Flexible sub-structure-use springs (such as on upper levels of building)

† Min. CFM to yield O.V. = 1850 FPM prevents entry of rain during operation. Low speed operation (2-sp. motor) could allow PPT. entry
Two speed operation is therefore limited. *Special motors p. 10. (X) Available models
Note: Motor and drive assembled and tested on fan panel
Fan panel, dampers and windband are separate for ease of handling in shipping and site location.
