Protocol Descriptions

TAS-201: Large Missile Impact Test (ASTM E1996)

The Florida Building Code requires that products installed in the Wind-Borne Debris Zone or High-Velocity Hurricane Zone must meet or exceed impact test criteria established under TAS-201. Products may be exempt if utilized in “open” structures or installed more than 30 feet (9 m)above grade. This test procedure measures a product’s capacity to withstand impact from wind-borne debris under hurricane-force wind velocities.

Test Fan Size: Maximum size selected by manufacturer for certification.

Test Missile: 7 foot ( 2.1 m) to 9 foot (2.75 m) long Southern pine 2 x 4; 9.0 to 9.5 pounds.

Distance from Front of Canon to Face of Fan: 9 feet (2.75 m).

Impact Velocity: 50 feet per second (15.25 m/s).

Procedure: Three specimens are tested. One impact is delivered at the center of each specimen and one impact is delivered at top and bottom of each specimen, for a total of three impacts.

Pass/Fail: Failure occurs if a change in the condition of the specimen results…such as “cracking, fastener loosening, local yielding” or if penetration of the projectile occurs beyond the inside plane of the fan.

TAS-202: Uniform Static Air Pressure Test (ASTM E330)

The Florida Building Code requires that all products utilized in structures located throughout the state meet or exceed the structural test criteria established under TAS-202. This test procedure measures a product’s ability to withstand maximum static pressure differentials typical to hurricane events.

Wind-Borne Debris Region (highlighted in blue)

Test Fan Size: Maximum size to be certified by manufacturer.

Design Pressure (Design Wind Load): Maximum positive or negative wind load to be certified by manufacturer.

Test Load: 2 x the selected design pressure.

Procedure: Specimen is subjected to a series of positive and negative pressures increasing from ½ test load to full test load.

Duration: 30 seconds maximum.

Recovery Period: 1 to 5 minutes.

Pass/Fail: Failure occurs if a change in the condition of the specimen results… such as “cracking, fastener loosening, local yielding” or, if permanent deformation results greater than 80% of maximum allowable deflection.

TAS-203: Cyclic Wind Pressure Load Test

The Florida Building Code requires this test to be conducted after completion of TAS-201: Large Missile Impact Test, to identify possible weaknesses resulting from the missile impact test. This test procedure assesses a product’s capacity to withstand wind vibration imparted under hurricane-force wind velocities.

Test Fan Size: Maximum size to be certified by manufacturer.

Design Pressure (Wind Load): Maximum positive or negative wind load to be certified by manufacturer.

Load Sequence: Application of positive load test followed by application of negative load test.

Duration: 5 seconds maximum.

Procedure: 600 cycles at 1/2 x design pressure; 70 cycles at 0.6 x design pressure and 1 cycle at 1.3 x design pressure.

Pass/Fail: Failure occurs if a change in the condition of the specimen results…such as “cracking, fastener loosening, local yielding” or if permanent deformation results greater than 80% of maximum allowable deflection.

Roof Curbs

Greenheck hurricane and high wind fans are designed for easy mounting to a variety of roof curbs. For your convenience Greenheck offers the industry’s largest selection of tested and approved High Wind and Hurricane roof curbs. Greenheck Models GPF, GPFP, GPFV, SD and SDP curbs offer fully configurable sizes for both flat and pitched roofs. Selectable in sizes up to 80 x 80 inches (2032 x 2032 mm) and heights ranging from 8 inches (203 mm) to 24 inches (610 mm) tall.

For applications where factory supplied curbs are not an option, the Greenheck high wind and hurricane fans can be used in conjunction with any previously installed or customer supplied curbs as long as they meet a series of minimum requirements. Considerations like no wood nailers, minimum material gauges and specific material types may allow field supplied curbs to be acceptable.

GPFThe GPF is a straight sided curb constructed of heavy gauge galvanized steel with a 5-inch (127 mm) flashing flange. It is designed specifically for use in high wind applications on flat roofs. Roofing material can be wrapped up over the top of the curb or can be directly flashed to the side of the curb for a complete tested and certified installation.

GPFPThe GPFP is similar in construction to the GPF. It is constructed of heavy gauge galvanized steel and can be configured to match the pitch of the roof ensuring that any fan mounted to the GPFP is going to sit level and operate properly. The 5-inch (127 mm) flashing flange can be used to secure the curb to the roof of metal (steel), concrete or wood frame building and easily flashed over to ensure weather tightness.

Roof Curbs

GPFvThe GPFV vented roof curb is typically used for kitchen applications; the vents allow hot air and gases to escape between the ductwork and roof curb. This curb is designed for use with Greenheck fan models CUBE and CUE to provide the required 40 inch (1016 mm) minimum discharge height above the roof line per NFPA 96. This curb is to be used on non-insulated flat roof decks. Model GPFV is mounted directly to the roof deck structure, roofed to the vertical surface and sealed to the 5-inch flashing flange. It is available in nine different sizes.

Special Purpose Roof CurbsSDThe SD curb is Greenheck’s highest strength curb constructed with a minimum 12 gauge high strength steel. A 2-inch (51 mm) reinforcement angle is provided on taller sizes. The fan curb is coated as standard with our Permatector™ high performance coating (other coatings available). The SD curb is available in heights up to 24 inches (610 mm) and is ideal for larger and heavier units or areas where the wind speed are the most extreme.

SDPThe SDP curb is similar in construction to the SD. Minimum 12 gauge steel with the 2-inch (51 mm) reinforcements and a 4-inch (102 mm) flashing flange make it strong and easy to install. The curb can be configured to match the pitch of a sloped roof so that the fans sit level on the curb. This curb is ideal for supporting heavier, larger equipment or for use in extreme wind conditions.

Laboratory Exhaust SystemsEntire Vektor product line

The entire product line of Vektor laboratory exhaust fans are designed to withstand 125 mph windload ratings. No guy wires are needed on these products, allowing complete systems in this line to be installed more efficiently with fewer roof penetrations in the field. For more information on all the benefits of these high wind Vektor products, please refer to any of the Vektor Laboratory Exhaust Systems product catalogs or contact the factory.
