FIXED ROUND CEILING DIFFUSERS & GRILLES APPLICATION

Transcription

1 SH.RDI.F1 SH.RDI.F FIXED ROUND CEILING DIFFUSERS & GRILLES APPLICATION SH.RDI.F Shahrokhi fixed round ceiling diffusers & grilles are designed to suit H.V.A.C applications for ceiling mounting or exposed duct. These diffusers are used for supply, return and exhaust air which provide a stable pattern of horizontal air diffusion flowing in every way through a number of concentrically arranged vanes. These diffusers are constructable in types of F1a, F1b, F, F, Fa, Fb (Figures 1-). SH.RDI.F Fa,F,F,F1b,F1a Fb 0 0 (FIGURE 1)
