Continuos Slot / Linear Diffusers

Air Diffusers supply and exhaust ventilation systems continuous slot and linear louvre diffusers introduction The LCS series diffuser has been developed to provide a simple and economical form of continuous slot air distribution system and is suitable for variable air volume schemes or fan coil applications. The air direction blades are readily adjustable from the diffuser face and have been designed to minimise discharge air turbulence, resulting in low pressure loss and low noise generation characteristics. The LCS system is completely modular, offering single section lengths up to 2m, in maximum widths of 6 slot. The frame and intermediate sections incorporate alignment plate slots to ensure section joins. Preformed corner sections can also be supplied to suit building contours, thereby eliminating site trimming. The standard finish is satin anodised frame and ‘T’ sections with matt black blades. A wide range of paint finishes are also available in BS or RAL colours. The following designations should be used when specifying the required finish: A = Satin anodised frame with black blades. B = Specified frame colour with black blades Control options include diffuser mounted opposed blade dampers (OB) or spigot mounted flap dampers (FDQ Quadrant operated or FDC Cord operated). The yoke strap fixing method is offered as standard, providing ease of installation when used with Brooke Air plenums. The installation procedure is similar to that for Flowline diffusers, details of which are given on page 11. A full range of plenums are available to suit a variety of installation conditions.
