<p>The air gun comprises a substantially cylindrical-shaped external case (2), provided at one end with a connection element (8) suitable to enable the connection of the air gun (1) with a device for supplying a fluid to be sprayed, and provided at the opposite end with an expulsion device (10) suitable to enable the outlet of the fluid to be sprayed towards the outside. Inside the case (2) is arranged a vortex generator device (9) provided with a plurality of internal walls (91) having curvilinear profiles. The walls (91) define a plurality of separated helical pipes (93), in order to give the fluid to be sprayed a helical rotatory motion.</p> |
