The HCCD range of high ceiling circular diffusers are designed for larger spaces with higher ceilings. They can be mounted in most ceilings and suspended from ductwork. The centre of the diffuser is removable and adjustable, allowing for a range of air patterns from horizontal to vertical projection. The HCCD is manufactured from aluminium and designed for high air flows with lower noise levels due to the sleek cone shape. The finish is powder coated RAL9016.
