Greenheck has developed a Mega-Stack option for the FumeJet fans. This is ideal for low flow applications where additional stack height is needed to provide a safe plume rise. With the Mega Stack, there are 10 foot and 15 foot options. The fan is curb cap mounted and includes neoprene isolators. All Mega Stack options come with a 24\" curb. The GFC curb is rated for a 115 mph wind load with no guy-wires needed. The fan housing outlet is flex connected to the stack. The FJI is currently the only fan available with the Mega Stack at this time. There are also multiple discharge options including a straight stack, a fixed nozzle, an adjustable nozzle, and a no loss stack. The straight stack is the most economical options, while the fixed nozzle creates the highest exit velocity. The fan can be horizontally ducted, most commonly used with the FJI, and vertically ducted for the FJC. VFD options are also available for both. Finally, the fans can be isolator or curb mounted. The FJC has a max CFM of 5,000, while the FJI can produce 18,000 CFM. Please contact Rob Laneve at email@example.com with any questions or submittal requests.
