A ventilation grill is an opening designed for air intake or exhaust, commonly installed in residences, buildings, public facilities, and other places for ventilation and air supply. They generally fall into two categories: exhaust grills and supply grills.
These grills facilitate airflow, with the speed and direction controlled by blades or fans within the structure. The blades or fans, usually powered by a motor, regulate the air movement in and out of the grill.
Notable features of ventilation grills include ease of installation on walls or ceilings, the ability to adjust air inflow and outflow, and a variety of design options. Some grills come with additional functionalities such as soundproofing, insect prevention, and noise reduction, enhancing environmental comfort by mitigating noise and preventing insect entry.
