HELLA Linear Diffusers

HELLA is a linear slot diffuser with a slim, compact and contemporary design that makes it suitable for a wide range of installations. Available in different sizes, it is widely used in offices, shops, medical rooms and school classrooms, where it is mainly intended to provide efficient air supply in comfort ventilation systems. The supply airflow pattern can be formed by adjustable deflectors in vents and the airflow volume can be tuned by the slider adjustment damper. Air extraction is also possible with HELLA. The diffuser is typically installed into a suspended ceiling as individual pieces or in an array of multiple segments. 

HELLA is manufactured from aluminium profiles making it robust as well lightweight. It also features a galvanised steel slider adjustment damper that can be attached or detached without tools. The end caps are fixed by screws but can be dismounted to install a continuous array of multiple diffusers. A galvanised steel plenum box with a circular duct connection can be delivered as an accessory to the diffuser with optional inside or outside insulation.
