The GL595/450-4W louvre faced ceiling diffuser is constructed entirely from metal, including the frame, blades, and centre core. It offers a strong, lightweight design that will not rust or corrode, providing excellent diffusion performance for a wide range of HVAC applications. The welded core and frame ensure durability and reliability in demanding environments.
Application
Suitable for surface mounting or lay-in ceiling grids, the louvre faced ceiling diffuser is ideal for areas requiring cooling in high heat and humidity conditions. It also performs effectively in heating and cooling applications in cooler climates. The removable core allows easy installation, cleaning, and access to dampers located behind the diffuser.
