Duct Balloons
Reduce Maintenance Cost
This duct balloon was approximately 16’ x 14’ x 3’ deep with tapered sides to match the slope of the existing duct work as it tapered toward the ID Fan damper. Slope information can be taken from drawings or calculated by providing rise and run information via field measurements
This is a three section duct balloon that measures 34’ wide x 12’ high x 3’ thick that was used during SCR Reactor modifications
This is a 25’0” x wide x 13’6” high x 3’0” thick balloon for an SCR inlet damper application
This is a split design duct balloon for use on an Axial Flow Fan application. It measures 15’2” OD x 6’6” ID x 3’0” thick. It is wrapped around the fan discharge and then inflated using the supplied 120V blower. We have been told that the duct balloons provide excellent sound absorption qualities when used in high noise environments. High noise levels that are generated in the area of out of service fans from the adjacent operating fans can be greatly reduced by using this type of duct balloon. They help increase the number of man hours that workers can be exposed to based on current man power availability to get the job completed.
This is a 90-1/8” diameter x 36” deep duct balloon designed for use in primary air duct during maintenance of a coal pulverisor.
