FLOWTECH Linear Bar (LB) is a side wall grille with a combination of fixed profile front horizontal blades and optional adjustable vertical rear blades. With its high capacity as well as its pleasant aesthetic appearance FLOWTECH Linear Bar Grilles & Registers are commonly used along sides of relatively large spaces with double void areas such as Domes, Open Lobbies, Malls, Atriums and Buildings Entrances, where both aesthetics and high capacity air volumes are required.

2 Double Deflection Linear Bar Grille (SLBG). For this purpose FLOWTECH LBG / LBR can be supplied in both straight and curved shapes to suit the interior geometry of the served space. FLOWTECH Linear Bars can also be used as conventional supply and return grilles, or combination. Thereof, blind dummy segments can be ordered to integrate the decorative outlook of the whole wall. Opposed Blades Dampers are supplied by FLOWTECH to achieve precise control over air flow volume. OBD is used for fine tuning of air flow volumes and should not be used as branch volume control damper. Single Deflection Linear Bar Grille (RLBG). In FLOWTECH SLBR & SLBG, vertical rear blades are used for directional air flow control.

3 Typically these blades can be adjusted to achieve the required air distribution pattern. Crown Shape Linear Bar Grille Rev. 0:2005/1 D-1. FLOW "~TECH. AIR DISTRIBUTION SPECIALIST.

Crown Shape Linear Bar Grille Product Features: Crown linear grille is a short radius curved linear grille, especially manufactured to suite the crown head or bottom of circular columns with a minimum radius at 250mm. The crown linear grille can be used as supply grille, Minimum Radius: 250mm return grille, dummy grille, or combination thereof. The crown linear grille has the same performance characteristics as linear grille with length modified as: L effective = 2 (r - ). where, r = curvature radius in meters Crown Shape Linear Bar Grille Leff = equivalent length in meters.
