Ultimate Steel Grease Exhaust Fan

Designed for severe grease applications...

When you choose a Greenheck USGF fan, you have selected a fan with the industry’s best performance and durability for heavy grease applications (as stated in NFPA’s Chapter 11 restaurants and food service where high amounts of grease and/or solid fuels are used). The USGF fan is specifically designed for severe grease applications and to discharge air directly away from the mounting surface.

• Leakproof construction for the entire life of the fan utilizing a one-piece steel windband that is

continuously welded to the curb cap.

• Only spun steel fan in the industry.

• Performance up to 3.25 in. wg (810 Pa) and 6,800 cfm (11,550 m3/hr).

• Withstands the most severe cleaning conditions.

• Most advanced motor cooling of any grease fan. Capable of continuously handling 400° F airstream

temperatures.

• Performance as cataloged is assured. All fan sizes are tested in our AMCA Accredited Laboratory, and all

models are licensed to bear the AMCA Sound and Air performance seals.

• UL Listed for electrical and grease applications.

• Greenheck subjects these products to extensive life testing, assuring you that the fans will provide many

years of reliable performance.

• Only kitchen exhaust fan to meet Miami-Dade Test protocols for large Missile Impact Test.

World-Class Manufacturing

Greenheck’s skilled production workers use cost-effective machines and unique dies designed and built by our own engineers to add innovative features and greater strength to our centrifugal exhaust fans. Our advanced manufacturing processes and quality control procedures always ensure the highest product quality. And just to be sure you get the peace-of-mind you expect when you specify Greenheck, our assembly inspectors test run and monitor every fan before it leaves the factory. Results of these tests are kept in permanent records for future reference.

Severe Weather Applications

Forceful winds and wind-borne debris are the cause of most hurricane damage. Hurricane winds start at 75 mph. At speeds of 140 mph wind can exert a 130 pound per square foot pressure or 900 pounds of force on a fan and curb. Forceful winds are not the only problem; wind-borne debris can also cause detrimental effects to objects and structures.

Miami-Dade County has the strictest test protocols in the country for wind-borne debris and wind loading tests. Greenheck has gone one step further with the model USGF by third-party testing to the Miami-Dade County Test Protocols.

These protocols were designed to protect against wind-born debris and severe wind loads.

• Structural Performance per Dade County Protocol TAS 202 (ASTM E-330).

• Large Missile Impact Testing per Dade County Protocol TAS 201.

Structural Performance Load: A static load that is 1.5 times the design load (195 pounds per square

foot pressure) is applied both positive and negative to simulate wind force loads in each direction.

Large Missile Impact Test: Is required when objects are located 30 feet or less from the ground. The

test unit is impacted three times with a piece of lumber (2 in. x 4 in. x 6 ft) weighing approximately nine pounds and traveling at 34 mph. This simulates wind-borne debris striking the fan.

Miami-Dade County test protocols: Greenheck has gone the extra mile and worked with Miami-Dade

County to design a High Velocity Hurricane Zone standard for rooftop fans. The USGF has become the first rooftop fan certified and approved by the Miami Dade Building Code Compliance office and Texas Department of Insurance for use in hurricane zones. The certifications can be viewed on the Miami-Dade County website under NOA #07-0503.06 or the Texas Department of Insurance Windstorm website.

When severe weather is a threat, don’t specify anything less than the Greenheck model USGF and the SD curb.

Standard Construction Features

Fan Shaft - Is 1-inch minimum in diameter and is

precisely sized, ground, and polished so the first critical speed is at least 25% over the maximum operating speed, which results in longer fan life.

Bearings - Lubricatable cast pillow block and are

air handling quality extended life L10 > 100,000 hours (L50 average life > 500,000 hours)

True Vibration Isolation - Lowers sound levels

and reduces vibration, which increases the fans life since true vibration has no steel to steel contact.

Clean Out Port - Allows the outside of the wheel

to be cleaned through a four-inch diameter removable plug in the windband.

Non-Stick Coated Steel Wheel - Heavy

weight steel wheel with a dry lubricate coating eliminates imbalance in heavy grease applications. The steel wheel is a backwardinclined, non-overloading centrifugal type.

Drain Trough - All grease and water is collected

at one-point for easy disposal.

Curb Cap with Mounting Holes - Prepunched

mounting holes in the steel curb cap to ensure correct attachment to the roof.

Hinged Curb Cap with Cables - Allows entire fan

to tilt away for access to wheel and ductwork for inspection and cleaning. Shipped for field assembly.

Leakproof Construction - One-piece fully welded

windband to curb cap. Assures no grease will leak onto roof through the fan’s seams.

Drive Assembly - Dual belts, pulleys, and keys are

oversized 150% of driven horsepower. Machined cast steel pulleys are adjustable for final system balancing. Belts are static free and oil resistant.

Motor Cover - Is easily removed for access to the

steel motor compartment and drive assembly.

Powder Coated - Unit is constructed of a minimum

of 16 gauge galvaneal steel. Entire unit is powder coated with a chemical resistant Permatector finish.

Motor - Carefully matched to the fan load and is

mounted out of air stream.

Windband - Unique spun from galvaneal steel

achieves superior strength & consistent material thickness.

Nema-3R Disconnect Switch Mounted & Wired -

Motor and switch are prewired to specified voltage.

Motor Cooling Tube - Maximum motor life is

achieved through positive motor cooling with fresh outside air being continuously drawn through the large breather tube directly over the motor.

Name Plate - Exact model and serial identification

on a permanent stamped aluminum plate.

Heat Baffle - Extends motor life by reducing the

amount of heat that penetrates through the bottom of the motor support pan.

Lifting Lugs - Located under motor compartment

for ease of lifting unit during installation.

Severe Duty Curb: Model SD is specifically

designed for the optional hurricane use. It is attached directly to the building structure with extremely high structural design load requirements. Maximum design load is 130 psf.

Drain Connection:

Allows for single point drainage of grease, water or other residues.

Grease Trap: Aluminum
