Device and method for diffusing dry fog

An anti-condensation housing, comprising:

• a bottle containing a product to be nebulized;
• a diffusing head connected to a compressed air inlet communicating with an inside of the bottle to nebulize the product;
• a tube comprising a diffusing end, an insufflating end, a bent portion at 90° between the diffusing end and the insufflating end, wherein the, tube has a section with an inscribed circle with a diameter between 60 mm and 120 mm, the section of the tube being continuous and forming a single flow path from the insufflating end to the diffusing end, and over a length between 3 and 10 times the diameter of the inscribed circle, a bending position is configured such that the tube surrounds the bottle and directs an airflow downward at the diffusing head when the bottle is in a vertical position, and a connector to connect the diffusing head to a nebulized product inlet between the diffusing end and insufflating end;
• wherein the compressed air inlet is independent from the tube;
• an outlet opening at the diffusing end of the tube;
• a fan at the insufflating end of the tube, the fan generates an air flow at a flow rate of at least 35 m3 per hour between the insufflating end and the diffusing end of the tube;
• a baffle inside the tube, located between the nebulized product inlet and the diffusing end, upstream of the bending position with respect to the air flow, the baffle extending along a direction perpendicular to a direction of the air flow in the tube to provide an obstacle for a progress of the air flow in the tube between the nebulized product inlet and the bent portion, and a height of the baffle is configured to intercept large droplets of the product with a diameter equal to or above 10 μm and to permit droplets with the diameter below 10 μm to go through;
• and
• the baffle cooperates with a wall of the tube to create a retention zone in the conduit to retain a nebulized product stopped by the baffle.
