- Nominal Size: 48″ x 2″ (please refer to size chart for details)
- Model #: WASD25-1/81W/1247L/005-US
- Our slot diffusers include a weather stripping seal to prevent ceiling smudging caused by some substandard performance air vents with air leakage issues.
- With a rich powder coated finish, these strong aluminum profiles and reinforced tig-welds are resistant against cracking, chipping, and bent corners. You will definitely be able to tell the difference when you are installing them.
- ***Please note that this listing does NOT include fasteners & plenum. There are no pre-drilled holes on the surface. Fastening must be done on the inner border sides for an aesthetic appearance. This product can be used as a supply or return air terminal.
- Our linear slot diffusers are made with 6063-T5 Grade Extruded Aluminum. This grade of aluminum has a relatively high tensile property with superb finishing characteristics and is excellent against corrosion. The 6063-T5 grade is often specified for architectural projects such as mansions, hotel resorts, and other commercial projects. Aluminum has a lot of different grades and therefore it is important to know what grade is used if you are looking for durability as not all slot diffusers use the same grade.
- HVAC Professionals: This product is tested in accordance to: ADC1062:GRD-84 (ADC1062R4) and ASHRAE 70-2006 “ Method of Testing the Performance of Air Outlets and Air Inlets (ANSI approved) ” . Additional performance data and engineering supportive documents are available on the authorized North America Manufacturer’s website. Our air ventilation products are constantly under research and redevelopment utilizing today’s testing standards and computational fluid dynamics simulation (CFD) energy models.
- What constitutes commercial grade grilles, registers, and diffusers (GRD)? A commercial grade product should have a complete set of technical data that would assist architects, engineers, and HVAC professionals to select the proper products for their projects. A standard commercial product should have the following information: Listed specific material and grade used as the primary composition material, Comprehensive product performance data (flow rate, static pressure, noise level and more). Please refer to our performance data for details or contact us via the “Ask a question” tab if you need further assistance.
- We have been producing quality 1 to 12 slots linear diffusers in a wide range of sizes for the HVAC industry since 1997.
