Emergency Smoke Control - GB

When you buy a Greenheck model GB with the smoke control option, you receive a fan with the industry’s best performance and durability for smoke control applications (as found in emergency smoke control systems)..

GB smoke control models are: 101, 101-HP, 121, 131, 141, 141-HP, 161, 161-HP, 200, 240, 300, 360, 420, 480

•UL/cUL Listed for 500°F (260°C) for 4 hours and 1,000°F (538°C) for 15 minutes..

•Half the weight of traditional smoke control fans, ideal choice for roof load concerns..

•Low profile, height is less than half of traditional smoke control fans, maximum of 521⁄2 inches (1334 mm) from curb cap to top of fan..

•Multiple applications, capable of exhausting general clean air and satisfying emergency smoke control regulations..

Seismic - G and GB

With changes in building codes and standards more equipment is being required to be seismically certified in areas of the country not commonly thought of as being in seismically active zones.

The International Building Code (IBC) is designed to provide model code regulations that safeguard public health and safety in all U..S.. communities.. This code is intended to improve the performance and design of non-structural systems subject to seismic events..

The State of California, one of the most active seismic areas in the United States, has the Office of Statewide Health Planning and Development (OSHPD) to regulate the design and construction of

healthcare facilities to ensure they are safe and capable of providing services to the public after

a seismic event. OSHPD developed their own unique certification process to incorporate the IBC and ASCE testing standards to ensure equipment remains operable after a seismic event..

Protocols designed for seismic standards:

	All Greenheck seismically certified models have been tested using the most severe seismic event that
Seismic	is found on the Spectral Response Map per IBC Figures 1613..5 (1-2).. Our testing is performed under
	the worst case scenario using the highest mapped seismic load, highest level occupancy category,
Testing Criteria
	worst case site class, and highest code mandated importance factor, thereby allowing Greenheck’s
	seismically certified fans to be used anywhere in the United States under any conditions
	The California Office of Statewide Health Planning and Development (OSHPD) requires all certified
California OSHPD	models be shake table tested in accordance with ICC ES AC-156, in which the fans are physically
	subjected to the same or greater forces than they will see during a seismic event. Subjecting
Test Protocols
	Greenheck model G and GB fans to this type of testing ensures the fans will operate without
	problems after a seismic event..
OSHPD Certification	The OSHPD certification numbers and supporting documents can be viewed on OSHPD’s
No.. 0148-10	website ensuring that the fan has been subjected to and passed rigorous testing standards.
State Licensed	When using the fans in applications which are not covered by California OSHPD standards,
	Greenheck models G and GB have been certified by a third party engineering firm to IBC 2006, 2009
P..E.. Calculations	and ASCE 7-05 standards.. These engineers hold professional engineering (P..E..) licenses in all 50
	states, so no matter where your job is located, you are backed by a P.E. signature for your state.

All Greenheck seismically certified fan models have gone through extensive testing procedures.. Greenheck models G and GB have been certified to IBC 2006, 2009, ASCE 7-05 and California OSHPD standards through both engineering calculations and shake table testing of all models by independent third party engineering firms..
