Ventilera

Ventilera is a Spanish noun that denotes an opening or device designed to allow air to circulate, providing ventilation. In architecture and building services, it typically refers to a vent, grille, or duct cover—an opening that enables air exchange between interior spaces and the outside or between different zones inside a structure. Ventileras can appear on walls, roofs, ceilings, or equipment housings and may be implemented as decorative or functional grilles that protect the opening while regulating airflow.

In everyday use, ventilera can describe the small vents found in appliances, heaters, or vehicles, such as a dashboard air vent or a range-hood outlet. The term often implies both the slit or opening and the accompanying cover, grille, or damper that controls access to the vent.

Etymologically, ventilera derives from ventilar, which means to air or ventilate. Related terms include ventilación (ventilation), ventilador (fan), and rejilla (grille). The concept is distinct from ventrílocua or ventriloquía, which refer to ventriloquism and the performer, rather than to physical ventilation openings.

Regional usage may vary: in many Spanish-speaking contexts, ventilera is commonly understood as an air-vent opening or its covering grill, while in some technical or industrial settings more specific terms such as boquilla de ventilación or rejilla de ventilación may be used.
