2 Contents Description Description Constructions Dimensions Dimensions Nomenclature Aerodynamic Data Order Details Characteristics Primarily used for supply air applications but can be used for extract when matching diffusers are required. Top entry supply air connection. Recommended supply air temperature difference -5 to -10 K. Type LFP-Z for supply air applications. Type LFP-A for extract air applications. Description The Laminar Flow Panel type LFP has been developed for specialist applications where the mixing of supply air with room air must be avoided. The diffuser provides a stable, low turbulence vertical discharge into the occupied zone. This makes the TROX type LFP ideal for clean rooms, labratories, operating theatres, broadcasting studios and computer rooms. Materials TROX type LFP comprises of a pre-galvanised steel facia panel, perforated to provide approximatley 28% free area. An optional extruded aluminium profile (..-F) can be specified to frame the LFP diffuser to suit integration within plasterboard (MF) suspended ceiling systems (...-1, 2 & 3 only). Integral pre-galvanised plenum box is fixed to the rear of the diffuser facia and is supplied with a top entry air spigot connection. All visable surfaces finished in polyester powder coat to RAL 9010:20% gloss as standard. 2
