Construction Features

Wheel construction

Wheel Sizes 7” through 18”Double width, double inlet fan wheels are constructedof galvanized steel, forward curved blades lock formedinto end rings. A structural steel plate mounted in thecenter of the wheel supports the shaft and stabilizesthe blades.

Wheel Sizes 20” through 30”

Double width, double inlet fan wheels are con-structed of galvanized steel, forward curved bladesriveted to a structural steel center plate and to theend rings. Factory mounted and tested, adjustabletie rods are provided on wheel sizes 20” through30”. The tie rods increase the strength and sta-bility of the wheel during high speed operation.

Bearings

Class L and RDeep groove, self aligning ball bearings are permanentlylubricated and sealed. The bearing is mounted insidea rubber isolator and attached directly to the fanhousing with a three prong mount. Maximum airtemperature for these bearings is 185ºF . The minimumair temperature is -4ºF.

Class K and K2Deep groove, self aligning ball bearings are mountedin a single piece pillow block housing. The bearingscan be lubricated and have a minimum rated bearinglife of 40,000 hours. The bearings are mounted ona sturdy angle iron base and welded to the frame.Maximum air temperature for these bearings is 212ºF.The minimum air temperature is -4ºF.

Hubs

Hubs secure the fan wheel to the shaft. On size 7/7wheels, the hubs are manufactured out of machinedsteel bars. Heavy duty forged steel hubs are used on

wheel sizes 9/7 through 30/28. These hubs are milledto a smooth nish at the base and center of the hub.Hubs are lock formed onto the center disk of fan sizes7/7 through 18/18. Riveted or bolted construction isused on the larger fan sizes. Fans with hollow shaftsare held in place with a special locking collar. Thecollar secures the wheel to the shaft without addingthe weight of a solid steel hub.

Construction FeaturesConstruction Features

ShaftsShafts are C40 hot rolled steel, turned, ground,polished, and ring gauged for accuracy. Solid shaftsare coated for enhanced corrosion protection.

Coatings

Shafts, wheels and frames are coated with aprotective paint. Custom coatings can be suppliedupon request.

Optional ConstructionFans can be built with inlet cones made of aluminum,copper, or steel with copper rubbing strips for sparkproof construction.

Options:• Access Doors• Drain Plugs• Outlet Flanges

Housing ConstructionFan housings are constructed from a scroll, twoside plates and a cut off plate. For fan sizes up to18", the housing sides and scroll are spot weldedtogether to form a durable assembly. For fan sizes20" and larger, the side plates are lock formed tothe scroll for a durable, air tight construction withoutcompromising the galvanized surface coating.

Side PlatesSide plates are manufactured with pre-punched holesfor attaching mounting feet or side frames.

Cut Off PlatesCutoff plates are uniquely designed to ensure quiet,smooth airflow through the fan.

Accessories and Configurations

There is a limit to the size of the motor that can be mounted on the fan housing. The chart below lists therecommended motor sizes for each fan. Version 1 is the standard motor mount design. Version 2 uses customsupplied brackets that attach to existing holes in the housing sides.

Motor mounts can be fixed directly to the housing of the Class L fans. Motor mounts are sold as an acces-sory item and shipped separately from the fan. Motors can be unit mounted in any one of four positions shownbelow.

Fan Selection Guidelines

INSTALLATIONEach fan is supplied ready for installation. The basefeet for class L must be ordered as a separate itemfor field installation. The base feet package comeswith two opposed base feet, mounting screws, andfour vibration isolators that fit into pre punched holesin the feet. Fans equipped with side frames need noaccessory packages for installation.

Pulleys can be mounted on either side of the TFCfans. The four fan configurations labeled CW showthe fan and motor positions available for a clockwiserotation. The four fan configurations labeled CCWshow the fan and motor positions available for acounterclockwise rotation.

CW

CCW

FAN ROTATION AND DISCHARGE

The fan can be oriented in any one of four positions.Each piece of the side frame has mounting holes forbolting the fan onto an isolated base frame. Fansshould never be installed on their side (with the shaftvertical). Contact the factory if you require a non stan-dard installation. Motor mount packages can be pur-chased as an accessory for installing motors directlyonto the housing of the Class L model fans.

There is no need to specify fan orientation when plac-ing an order because of the complete versatility ofpositioning the fan in the field. Fan orientation mustbe indicated when some accessories are ordered suchas drain holes or plugs.

PULLEY SELECTIONProper pulley selection will aid the bearings in achievingtheir full life expectancy. The maximum number ofgrooves recommended for the fan models is givenbelow.

MOTOR SELECTIONHorsepower data on the fan charts are based on fanperformance tested with an open inlet and ductedoutlet in accordance with AMCA Standard 210. Find the recommended motor horsepower for a

Fans shall be forward curved, double width, double inlet, as manufactured by Twin City Fan Companies Ltd.,

Minneapolis, MN.

HOUSING - Fan housings are constructed of hot dipped galvanized steel for corrosion resistance. The scroll

has a rounded, smooth surface. The sides are supplied with inlet cones and are embossed for added strength.

A cut off plate completes the housing parts to add aerodynamic stability and to optimize fan efficiency. For

fan sizes up to 18” the housing sides and scroll are spot welded together to form a durable assembly. For fan

sizes 20” and above the side plates are lock formed to the scroll for a durable, air tight construction without

compromising the galvanized surface coating of the metal.

WHEEL - (Sizes 7” through 18”): Double width, double inlet fan wheels are constructed of galvanized steel,

forward curve blades, lock formed into end rings. A structural steel plate mounted in the center of the wheel

accurately positions the blades and connects them to the shaft. (Sizes 20” through 30”): Double width, double

inlet fan wheels are constructed of galvanized steel forward curve blades riveted or tab locked to a structural

steel center plate and to the end rings. Factory mounted and tested, adjustable tie rods are provided on the

wheels to increase the strength and stability of the wheel during high speed operation.

SHAFTS - Shafts are formed from C40 steel. The shafts are ground, polished and ring gauged for accuracy.

Standard fan assemblies are provided with coated solid shafts for enhanced corrosion protection. Hollow shafts

are supplied for double fans, Class K sizes 18/13 through 30/28, Class K2 sizes 20/15 through 30/28,

BEARINGS - (Class L and R): Deep groove, self aligning ball bearings are mounted inside a rubber isolator

supported on the fan housing with a spider mount. (Class K and K2): Deep groove, self-aligning ball bearings

are mounted in a single piece pillow block housing. The bearings can be lubricated and have an average rated

bearing life of 200,000 hours. Bearings are mounted on a sturdy angle iron base that is bolted to the frame.

FRAME CONSTRUCTION - All fan models can be field installed in any of four positions. Airflow can be oriented

down, up, or to the side (at 90°, 180°, 270°, 360°).

Class L - Fans are not provided with framing. Mounting feet are available as an accessory.Class R - Fans are provided with rectangular angle side frames.

Class K - Fans are provided with powder coated rectangular angle side frames attached to three angle cross

members.

Class K2 - Fans are provided with powder coated rectangular angle side frames attached to four angle cross

members.

WARRANTY - The manufacturer shall guarantee the workmanship and materials for model TFC fan for at least

one (1) year from startup or eighteen (18) months from the date of shipment, whichever occurs first.
