J-System B9 Fumigation Recirculation Blower

Improve fumigant distribution in large, tightly sealed grain-storage structures with the Degesch J-System® B9 Blower. This 1/2 HP low-flow recirculation blower draws air from the headspace and moves it through the grain mass to help fumigant concentrations equalize more quickly and uniformly. It is intended for trained fumigation professionals using the manufacturer’s J-System® method. Degesch recommends the B9 for storage capacities of 175,000 to 500,000 bushels (218,000 to 622,000 cubic feet). The blower is designed only for dispersing phosphine, methyl bromide, or sulfuryl fluoride as defined by the J-System® Low Air Flow Fumigation Method. Follow the applicable fumigant label, fumigation management plan, and Degesch installation, wiring, operating, and maintenance instructions. Some silos with separate duct systems may require more than one blower.
