Louvers application

Industrial louvers have many names with most defined by their purpose or operation. They include Industrial wall louvers, fresh air intake louvers, air intake louvers, ventilation louvers, fixed or adjustable louvers, manual or motorized louvers and exhaust louvers.

Louvers used for ventilation purposes are constructed of various metals and plastics, with fiberglass packing internals if needed, determined by their environment.

In many instances, these are readily available as in-stock items or custom designs with short lead times. Louver designs vary by blade type, blade angle, and percentage of the free area required for the application. Typical add-on options include bird screen, fasteners, and application specific paints. Wall opening sizing that can be covered is unlimited, as individual louvers can be coupled and assembled into complete wall structures.

Drainable and non-drainable designs are available to optimize airflows for louvers expected to be exposed to rain and snow.

Drainable blades contain gutters that drain water to the end of the blade and are typically used in locations where heavy rain is common. In contrast, non-drainable blades permit rain to fall directly off the blade into the incoming air path. Extreme weather louvers are intended to endure the harshest environmental factors, such as hurricanes.

In locations where extreme whether considerations must be made, drainable louvers are typically used. These louvers are composed of galvanized steel or aluminum, making them extremely durable. Penthouse louvers are constructed to protect rooftop air intakes and exhaust vents. The reinforced aluminum construction allows rooftop louvers to be durable and strong in harsh environmental conditions such as windstorms.

Louver selection is based upon weather conditions, airstream chemistry, and allowable pressure drop. Louver manufacturers publish performance information based upon AMCA test results for rain penetration, free area and pressure drop thru the louver.

The following are key performance parameters of a louver to be considered when choosing the appropriate size and performance to meet your needs:. Industrial louvers constructed of fiberglass are necessary where corrosive environments are prevalent in facilities such as wastewater treatment or processing plants where aggressive chemicals are common.

All components of FRP louvers are constructed with fiberglass and isophthalic polyester resin, making them resistant to aggressive chemicals and allowing them to carry a Class I flame spread rating of 25 or less. All joints are mended with industrial grade epoxy which has comparable corrosion resistance properties to polyester resin. FRP applications that exceed maximum size waypoint mavlink be custom designed with multiple panels reinforced construction.

Acoustic louvers are designed for noise mitigation from large building ventilation projects where operating machinery create objectionable noise levels outside the facility. They are fabricated of aluminum or galvanized steel in 6, 8 or inch depths and are all non-drainable design. Acoustic louvers have an outside top layer of metal, a bottom perforated metal sheet and a sound absorbent core, which is fire and water resistant. SysTech offers louvers suited to a variety of industrial duty air control applications, all engineered for optimal performance and efficiency.Your building is designed to accommodate a variety of features that enhance its function.

Some of these, like the downspouts and gutters, help drain water away to prevent the build-up of moisture within the foundation and structure of a building.

Other features like vents and windows facilitate the flow of air throughout the structure, improving air quality and comfort for everyone inside the building. Louvers are used in buildings wherever there is a need for creating resistance to rainwater, excessive noise, hurricane-type winds, or a combination of these problems — while also ensuring proper airflow. The answer is simple; they allow the flow of air, while blocking rain and debris from entering into the building.

Louver systems are installed on most buildings to ensure a smoother intake and exhaust of air, and also to provide stronger resistance against rain and noise intrusion. However, louvers have many uses for both engineers and architects.

Louvers can be utilized in a range of performance types, including drainable, non-drainable, wind-driven rain resistant, combination, thin-line, acoustically rated, adjustable, and even extreme-weather resistant.

When buying a louver system, make sure you have a clear understanding of the purpose of louvers and how louvers work so you can be sure that you are purchasing the right louver design for your needs. Also, ensure that the louver system has an AMCA rating, which denotes that it has been tested and certified by the Air Movement and Control Association AMCA ; it can be found in the technical data sheet provided by the manufacturer.

The use of louvers can vary from building to building, depending on its design and capacity. For example, a car park might require good airflow, but it may not need maximum protection from the rain so that a conventional louver design would be more than enough. On the other hand, the generator or plant room that contains electrical equipment may require fool-proof protection from storms and hurricanes as well as high-performance airflow specs.

Louvers are made functional by fixed or operable blades installed on a frame. The number, size, and design of the blades depends on the type of ventilation and protection you require from the louver.

Each blade has a unique configuration, allowing for different things to pass through it. For example, a wind-driven rain louver may allow air through, but not rain, or in some cases, debris. Additionally, there are several things to consider when selecting an architectural louver system for your building.

These include:. A high-percentage free area is great because it allows for more air to enter via a smaller opening, thus reducing the expenses involved in opening up the wall and installing louvers. It is a measurement of free area velocity that tells us the threshold at which the louver will start leaking. For traditional louver designs, this varies from fpm feet per minute to fpm, with the latter denoting an excellent resistance to water entrainment.

Resistance to Airflow Pressure Loss. Every louver will create wind resistance based on its design as well as the shape of its frame and blades, and anything that obstructs the airstream creates resistance — such as ductwork, filters, coils, the building structure itself. It is essential to minimize this resistance where possible because it can be harmful to the louver and other air movement equipment. It is also vital to ensure lower energy consumption, as the lower the pressure, the less power will be required to operate the fan.

Architectural louvers are engineered to meet the demanding performance requirements of modern structures that are not only being built higher but also subject to more inclement weather and environmental elements than ever before.

There is no denying the fact that it is imperative for architectural louvers to strike a balance between aesthetics and performance — since they are visible from the outside of the building, these systems must be able to assimilate seamlessly into the building design. They can be installed horizontally or vertically, custom-shaped, and even finished in a variety of ways. Varying blade depths, and variable blade frequencies as well as a staggered placement of the blades can also play a role in creative design of louvers.

Here at AWV, we have developed a range of louvers to meet the complex needs of modern architecture, ensuring superior ventilation and protection at the same time. Our louver line-up offers an array of weather protection capabilities, styles, and blade profiles to suit all the requirements of your project.
