Configurations The SMH comes in different pre-set modules. From 1Hx1W up to 3Hx3W for a total of up to 60 filter elements. For example, the one depicted in the picture bellow is 2Hx2W. 11
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. The following example compares two louvers for a wall opening size of 48" wide x 48" high with different performance characteristics: Louver Free Area (percentage) Free Area for 48" x 48" (square feet) First Point Water (fpm) Design Velocity (fpm) Volume of Air (cfm) 1 45% 7.2 1190 893 6426 2 53% 8.5 750 563 4781 12
