Floor slot diffuser FBS Description Quick selection (L=1000, damper OPEN, at LWA = 35 [dB(A)]) Properties High vertical penetration depth at high ∆T. Supply air jet is spread over a large area with very quick temperature and flow velocity reduction. A subsequent adjustment of the air jet pattern to changed room conditions is possible. Wide volumetric flow range at low sound power level. At a very low air volume, the supply air jet is similar to a displacement diffuser, but has better temperature reduction. For large air volumes, the FBS is particularly suitable as air curtain ventilation. Suitable...
