Abstract
A sealant injection unit for a duct sealing includes a reservoir configured to store sealant, and a nozzle fluidly coupled to the reservoir and configured to inject the sealant inside an airstream injected inside a duct. The sealant injection unit further includes a pump configured to pump the sealant to the nozzle at a desired pressure, and a three way valve arranged between the pump and the nozzle and configured to selectively connect the pump to the nozzle or the reservoir.
