A modular element (1) for dynamic air curtain barriers (2), said modular element (1) comprising: a supporting frame (3) having a lateral wall (4) internally defining a housing compartment (5) and comprising a lateral through opening (8) substantially extending along a prevalent direction (D) of extension of the frame itself, a channel (9) engaged with the supporting frame (3) and configured to receive an air flow from the ventilating device (12) and channel it along a direction (S) of ejection out of said housing compartment (5) through the lateral opening (8). The channel (9) having a first and a second longitudinal channelling wall (10, 11) extending prevalently inside the housing compartment (5) along the prevalent direction (D) of extension of the frame (3); each channelling wall (10, 11) has an inlet portion (10a, 11a) located inside the housing compartment (5) and an outlet portion (10b, 11 b) located outside the housing compartment (5). The inlet portions (10a, 11 a) of the channelling walls (10, 11) define a lateral inlet opening (15), whilst the respective outlet portions (10b, 11b) of the channelling walls (10, 11) define an outlet opening (25) configured to direct the air flow along an ejection direction (S); the channelling walls (10, 11) define, in cooperation with each other, a duct (22) for the air flow extending between the inlet opening (15) and the outlet opening (25). |
