The units are available in three standard sizes with options for top, side, or end entry inlet spigots and screw operated louvre dampers. Support Brackets and mounting plates can also be manufactured to fit suspended light bases used in operating theatres. The LFM units can be supplied with a perimeter trim strip to suit the overall dimensions of the panel assembly. Laminar flow diffuser generates a low velocity, evenly distributed, downward moving piston of conditioned air Helps to protect patients from contaminated air. The column-like airflow displaces airborne particulate down and away from the area below the diffuser. The diffusers are available with either a flanged frame style (type LFF) to suit conventional exposed or concealed âTâ ceilings, or, with a flangeless frame (type LFM) suitable for modular panel constructions. Overview Laminar flow diffusers are engineered to provide a uniform, unidirectional low velocity air pattern. Creating a custom layout which utilizes job specific sized laminar flow diffusers (figure 11) is the best way to ensure that ASHRAE 170 requirements are met while maintaining all laminar flow diffuser functionality. The laminar air pattern is achieved by use of a primary baffle within the plenum chamber and a low free area perforated discharge plate at the face of the diffuser. cleanability of the laminar flow diffusers. Including snap-in, autocentering filter retainers, the new TLFR reduces the amount of time and effort during installation and. Used in operating rooms as the primary diffusers, the vertical piston of air created by the TLFR is used to discharge clean air over the patient during operations. AIR DISTRIBUTION STRATEGIES FOR CLEAN ROOMS. Laminar flow diffuser, stainless steel or aluminum. They are also suitable for less critical applications such as animal rooms or kitchens where a vertical flow pattern may be required. laminar flow, the airflow velocity and a constant airflow must be maintained. LF diffusers have been designed for use in Clean Rooms, laboratories, operating theatres, or other applications where critical control of room air movement is necessary.
