Tube Axial Roof Upblast Fans

Greenheck’s tube axial upblast roof exhausters, both direct drive and belt driven, are designed to efficiently
remove and disperse contaminated air. The upblast configuration is ideal for exhausting contaminants away
from a building to prevent roof damage and re-entrainment of exhaust air.

Greenheck’s versatile tube axial design can be used in most commercial and industrial applications. Typical
applications include:

• General exhaust

• Industrial space ventilation

• Fume hood exhaust

• Paint booth exhaust

TAUD Features:

• Direct drive construction

• Propeller diameters from 18 to 48 inch (457 - 1912 mm)

• Volume Range: 2,800 to 46,000 cfm (4,760 - 78,100 m3/hr)

• Static Pressure: Up to 1.0 inch wg

• Temperatures: Up to 110ºF (43ºC)

(250 Pa)

TAUB-CA Features:

• Spark resistant construction

• Belt drive with motor and drives out of airstream

• Propeller diameters from 18 to 60 inch (457 - 1524 mm)

• Volume Range: 2,800 to 74,000 cfm

• Static Pressure: Up to 1.25 inches wg (310 Pa)

• Temperatures: Up to 180ºF

(82ºC)

(4,760 - 125,700 m3/hr)

Cast Aluminum Propellers

The TAUD and TAUB-CA use heavy duty, cast aluminum airfoil propellers that are designed to
meet a large range capacity and pressure requirements.

All TAUD and TAUB-CA propellers are dynamically balanced to assure vibration free
operation. All propellers are tightly secured to the fan or motor shaft with taper lock
bushings.

Quality Design

Construction includes heavy gauge material used in the housing, windband, and curb cap. Rolled edges on the
windband and damper blades are used for additional strength. Curb cap includes reinforcing gussets, integral
venturi, and prepunched mounting holes.

Electrostatic Powder Paint

Powder coatings offer a uniform, durable, and high quality finish.
Powder coating is a one-coat process applied over a phosphatized
surface that generally meets or exceeds the corrosion resistance of a
comparable wet paint.

Greenheck offers a number of in-house coatings applied via
“electrostatic powder”. The standard coating, Permatector™, is
excellent for indoor or outdoor applications and is resistant to many
common chemicals. Consult Greenheck’s Product Application Guide
FA/110-04R, Performance Coatings for Ventilation Products for a
complete listing of coatings and a relative resistance chart.

Maintenance / Serviceable

The TAUB incorporates the following value added features that allow for quick and easy field service.

• Bearing lubrication is performed through extended grease fittings located on the
outside of the fan housing.

• An adjustable motor base is provided for tightening the fan belts.

• Propellers are easily removed with the use of taper lock bushings.

For best access to the propeller and internal fan components for field service, see
the “Easy Access Construction” option in the Accessories section.

Complete Assembly and Testing

The TAUD and TAUB-CA are completely assembled and tested before
shipment. Our inspectors check that the fan operates with minimal
vibration and is electrically safe for field operation.

Standard Construction
& Accessories

Standard Construction

®

Housing

Housings are continuously welded to prevent air
leakage. The fan tube, curb cap, windband and motor
cover are constructed of heavy gauge steel with
Permatector™ coating.

Butterfly Dampers

Butterfly style dampers feature rolled edges for
strength and weather protection. Damper stops
maintain proper blade position when fan is operating.
Gaskets line the edge of fan discharge for quiet
damper closure. For sizes 18-30 aluminum material
is standard and steel is standard for sizes 36-60.

Aluminum blades optional on larger sizes.

Bearings (Belt Drive)

Bearings are air handling quality, grease lubricated,
pillow block type. Bearings are selected with a basic
rating fatigue life (L10) in excess of 40,000 hours at
each fan’s maximum operating speed.

Extended Lube Lines (Belt Drive)

Extended lube lines with grease fittings allow bearing
lubrication from the fan exterior.

Accessories

Belt & Bearing Tube (Belt Drive)

Belts, bearings, and drives are protected from the
airstream by a heavy gauge steel belt tube and
bearing cover.

Adjustable Motor Bases (Belt Drive)

Rigid structural steel motor bases are welded to
the fan housing and include heavy duty adjustment
screws for belt tensioning.

Drives (Belt Drive)

Greenheck offers either constant or adjustable speed
drives for fan speed adjustments. Belts are static free
and oil resistant.

Motors

NEMA base-mounted motors are standard. Motors
are available in open drip proof, totally enclosed, or
explosion proof.

Motor Covers (Belt Drive)

Weatherproof motor cover shields the motor and
drive components from dust, dirt, and moisture. Motor
covers meet OSHA standards.

Outlet Screen

Outlet screens constructed of steel mesh shield
dampers and fan discharge from debris.

Fusible Link Damper Lifter

Automatically open butterfly dampers when the air
temperature below the damper blades exceeds 165ºF
(74ºC). Damper blades held open to provide smoke
and heat relief with no electric power required.

Magnetic Latches

Magnetic damper latches minimize damper flutter (due
to pressure changes within the building) when the fan
is not in operation.

Inspection Door

Bolted or hinged inspection door provides access
through the fan tube for cleaning or inspection of the
propeller, bearings, and drives.

Inlet Guard

Inlet guards provide protection for personnel and
equipment in ducted or non-ducted installations. Inlet
guards meet OSHA standards.

Extended Wiring (Direct Drive)

Motor wiring is extended to the exterior of the fan
casing for easy installation of the unit in the field.

Tie Down Points

A set of 4 tie down points are used to secure the fan to
the roof deck when wind loading is a concern.

Shaft Seal

Shaft seals with aluminum rub rings are available to
prohibit leakage of air into the bearing compartment of
the fan.

Special Coatings

Special coatings are available for protective purposes.
Coatings are applied before assembly so that each
manufactured component is coated inside and out.
Painting the exterior a specified color for appearance
is also an option. Consult Greenheck’s Product
Application Guide FA/110-04R, Performance Coatings
for Ventilation Products for a complete listing of
coatings and a relative resistance chart.

Roof Curbs

A complete line of prefabricated roof curbs is available
for mounting Model TAUD and TAUD fans. See the
Greenheck Roof Curbs, Extensions & Equipment
Supports catalog.

Disconnect Switches

Toggle and heavy duty disconnect switches are
available for positive electrical shut-off and safety in
servicing fans. The following switches are available
to meet individual electrical requirements and can be
factory mounted or shipped loose for field mounting.

• NEMA-3R — Rainproof (outdoor)

• NEMA-4 — Watertight (outdoor)

• NEMA-7 & 9 — Class 1 and 2 hazardous locations.

Greenheck will not factory mount NEMA-7 & 9 disconnect switches.
