Louvers
Louvers are very similar to dampers; the difference
being made by the fact that the slats are fixed at production
and their angle is not adjustable later on.
Louvers serve a critical need to allow air flow
through openings in air filtration systems while keeping out
unwanted elements such as water, dirt, and debris. The
basic considerations for selecting louvers are Louver Free
Area, Water Penetration, and Resistance to Airflow
(Pressure Loss).
Selecting the right product for the application is
important to meeting performance needs.
Built using no welding technology, cut and bend only this ensures:
• Lower manufacturing costs
• Easier and less expensive to transport
• Safer and more eco-friendly installation
• Easier to handle and unload
• Easier to repair.
Depending on the client needs, louvers can be made from aluminium,
steel or stainless-steel.
