What is an intake louver?
An intake louver is a fixed-blade grille set in an exterior wall opening that lets outside air into a building's ventilation system while shedding rain, snow and debris. Its angled blades turn water away, and a screen behind them keeps birds and insects out. An exhaust louver looks similar but discharges air instead. Interior grilles and registers are different products: they finish duct openings inside rooms and are not built to resist weather. Intake louvers usually feed an air handler, fan or plenum.

Questions
What is an air intake louver used for?
An air intake louver brings fresh outdoor air into mechanical equipment such as air handlers, make-up air units and generator rooms. It keeps weather and pests out while letting enough air through for the system to run. Drainable or storm-resistant blade styles are chosen where wind-driven rain is a concern, and the louver is sealed into the wall like a window.
Is an intake louver the same as an exhaust louver?
They are often the same style of product, and the difference is the direction of airflow. Designers keep intake louvers separated from exhaust louvers, plumbing vents and loading docks so dirty air is not pulled back into the building. Intake louvers also tend to get closer attention to water penetration because moisture drawn inside can reach ductwork and equipment.
