Abstract: A hand dryer device includes a casing, a drying chamber superiorly open formed in the upper portion of the same casing for placing the hands of the user, aeration means provided for orienting an air flow rate towards an outlet located in the area of the drying chamber, and detection means for detecting the presence of the hands of the user in the drying chamber. The drying chamber runs transversely from the front region to the rear region of the casing, the drying chamber being laterally delimited by two arms facing each other, which extend vertically from the corresponding lateral regions, the drying chamber having dimensions configured for the insertion of the two hands of the user from the front area of the casing. The air outlet is located on the internal face of the two arms; the air flow rate is laterally oriented towards the hands of a user.
