The process itself needs only a few steps. In preparation, all inlets and outlets of the air duct system are sealed with foam plugs or metal plates and are taped over with MEZ-DUCT-WRAP. The connections of the air duct to ventilation and air handling units, fans or heat exchangers are disconnected and built-in-sensors are taped over. so that no particles of the sealant can get into these components. On the other hand silencers and dampers don't have to be removed as long as they are completely open.
Then, the air duct is connceted to the MEZ-AEROSEAL equipment by the use of a transparent plastic hose.
