1 OVERVIEW Overview: The KPS series staircase swirl diffusers belong to the underchair diffuser category; ideal for places where the best comfort levels are desired both in temperature and acoustics. Cinemas, theatres and conference halls are some examples. Technical characteristics: The KPS series staircase swirl diffusers are realized in the models: -QQ squared diffuser, squared finned surface; -QC squared diffuser, circular finned surface; -CC circular diffuser, circular finned surface. Installation : With subframe -QQ-P -QC-P -CC-P With spigot and equalizer -QC-C -CC-C -QQ Finishing : Epoxy powder coating RAL 9 color Direction of the throw The spigor with equalizer ensures a horizontal air throw. -QC -CC U1 Diffusion-vers_17_.xls U1-11
