Louver vent applications
Louver vent electrical enclosures are used to provide ventilation in electrical enclosures where excessive internal heat or moisture may be an issue. They are designed to enhance cooling efficiency, optimise operation and extend equipment lifespan. Louvers are vents that allow for natural or forced ventilation from the panel interior that houses electronic devices. They are made of metal or resin material and feature slanted plates that are arranged side by side so that air ventilates through the gaps.
Louver vents are also designed to provide ventilation in enclosures for either indoor or outdoor locations. They can offer ingress protection for both solid debris and outdoor rain conditions. Some louver vents are designed for reliable rain defence, featuring a single-bank drainable blade system with vertical gutters integrated into a flanged perimeter frame. This design ensures water is directed away from the blades. Constructed from extruded aluminium, these louver vents support both intake and exhaust ventilation.
Louver vents can also be used in demanding environments, providing adjustable airflow and exceptional weather protection. They are ideal for gymnasiums, indoor pools, stadiums, and factories. Louver vents with exceptional rain defence and low-pressure loss are perfect for environments requiring robust ventilation solutions. The vertical blade design enhances airflow while using gravity and surface tension to direct water away, ensuring reliable performance in adverse weather.

Louver vent installation
Louvers are an important architectural feature of modern buildings, serving both aesthetic and functional purposes. They facilitate ventilation and temperature control by allowing airflow while also keeping out unwanted elements such as rain, debris, and insects. Proper louver installation is crucial for effective ventilation and the overall health of the building. Here is a comprehensive guide to installing louver vents:
Planning and Preparation:
Firstly, select the installation spot, which could be on the roof or an exterior wall. Measure the area carefully, considering factors like airflow direction. Ensure there are no pipes, wires, or structural elements in the wall that could be damaged when cutting the hole for the louver. Clean the chosen area thoroughly for a smooth installation process.
Cutting and Installation:
Measure the louver dimensions and mark the corresponding area on the wall or roof. Verify the measurements multiple times before cutting to avoid mistakes. Cut the opening carefully, ensuring straight edges. With the opening prepared, align the louver with the opening, making sure it fits securely.
Maintenance and Flashing:
Regular maintenance is essential to ensure the louver functions optimally and maintains its aesthetic appeal. Keep the louver and surrounding area clean and free of debris. Check for any signs of damage or wear and tear, and repair or replace the louver if necessary. Additionally, ensure that the louver is properly 'flashed', which means that the vent assembly contacts the house wall in a way that prevents water from entering through the sides or top. The manufacturer's instructions will provide specific details on flashing, as some vents are self-flashed, while others may require additional steps depending on the type of siding.

Louvers and air flow
A louvre vent electrical enclosure is a type of ventilation product that allows air to pass through while keeping out unwanted elements such as water, dirt, and debris. Louvers are required when buildings need to balance airflow and protection from external elements. They are particularly useful in spaces that house sensitive equipment, such as generators or electrical components, which require protection from extreme weather conditions.
Louvers are designed with a number of fixed or operable blades mounted in a frame. The airflow direction is an important consideration when installing louvers, as intake and exhaust louvers have different features. Intake louvers, which take air into the system, must be able to reject water and other unwanted elements. Exhaust louvers, on the other hand, do not need to worry about water infiltration as the exhaust air will push water away from the opening. As such, exhaust louvers can have blades with smooth profiles set at 90-degree angles.
The performance of a louver is influenced by factors such as air volume, face velocity, and system effects. Air volume refers to the amount of air flowing through the louver, expressed in CFM (cubic feet per minute). Face velocity, typically expressed in FPM (feet per minute), is the speed of airflow across the louver's face. System effects, such as ductwork behind the louver, can also impact the louver's air performance. Additionally, the free area of a louver, which is the total open area after subtracting obstructions like blades and frames, plays a crucial role in determining airflow. A high percentage of free area is desirable as it allows more air to enter through a smaller wall opening, reducing costs.
When selecting a louver, it is important to consider the level of protection required for the specific application. Louvers with higher protection, such as severe weather louvers and hurricane louvers, will have more resistance to airflow than standard louvers. This resistance is referred to as pressure drop or pressure loss, which is the loss of pressure as air passes through the louver. Manufacturers typically publish airflow resistance for their louvers, and this information can be used to determine the most suitable louver for a particular application.
