Additional specifications and description
High-performance swirl diffuser from the Belgian manufacturer Grada. The WT100 is designed for installation in suspended ceilings. It can function in both supply and exhaust ventilation roles. The individually adjustable deflectors allow the “throw” of air to be adjusted and optimised for the specific interior space. When used for supply ventilation the diffuser can take advantage of the Coandă effect to improve ventilation performance and allow fresh air to reach further. The swirl pattern allows for the rapid mixing of the incoming air and ambient air. An optional damper can be added to the intake of the plenum box to control the volume of air.
Diffusers in suspended ceilings are ubiquitous in offices, shopping centres, conference rooms and other commercial and public spaces. Because of the specific role and application of ceiling diffusers, the same model of diffuser is often used for both supply and exhaust ventilation. The Grada WT100 can work for both supply and exhaust ventilation and is well suited for most applications thanks to its excellent acoustic properties and control over the throw of air. Even when large volumes of air pass through the WT100, it maintains a low noise rating (NR), making it a perfect choice for offices.
Choosing the correct size of the diffuser and the number of diffusers required for each room can be determined by the dimensions of the space and the specific ventilation requirements.
Construction and mounting
The Grada WT100 adjustable swirl diffuser is constructed from sheet steel (the deflector blades are made from PVC) with a powder coating finish. The standard colour is RAL9010 white, but other colour options are also available from the manufacturer.
The WT100 is equipped with a plenum box with a perforated air flow control plate for volume adjustment, with either a top or side connection.
The spigot of the plenum features a double lip rubber seal, which helps the unit achieve an airtightness class D according to EN 12237.
Please note that the final airtightness of the ventilation system depends on multiple factors, including the installation method.
The standard mounting option is 7 mm mounting holes located on the plenum box.
Designed for modern interior spaces
Devices such as diffusers and grilles are usually the first or only HVAC components people notice when entering an interior space. Consequently, ceiling diffusers play a big part in the interior design of any commercial or public space. Like other Grada products, this swirl diffuser has a pleasing minimalist design and an impeccable powder coating finish. The Grada WT100 adjustable swirl diffuser will fit perfectly in most interior designs and elevate the feel of the interior space.
