Plain diffuser LCA
DescriptionLCA is a circular diffuser with an unperforated face plate thatcan be used for both supply and exhaust air. LCA is suitablefor the horizontal supply of cooled air where a high impulseis required. It can be equipped with accessories of varioustypes in order to achieve optimum function. Installing anLCA diffuser in a plenum box type MBA can help to achievea stable airflow to the diffuser as well as realise the potentialfor individual adjustment.
• Suitable for both supply and exhaust air• Suitable for the horizontal supply of cooled air• High impulse• Option of 1, 2 and 3-way supply air• Discrete design
MaintenanceThe face plate can be removed to enable cleaning of internalparts or to gain access to the duct or box. The visible partsof the diffuser can be wiped with a damp cloth.

Technical data
CapacityVolume flow q [l/s] and [m3/h], total pressure pt [Pa], throwl0.2 [m] and sound level LWA [dB(A)] can be seen in the dia-grams.
Frequency-related sound effect levelThe sound effect level in the frequency band is defined asLWA+Kok. Kok values are specified in charts beneath the dia-grams on the following pages. Kok values for LCA without abox are available on request.
Quick selection, supply air
Sound attenuationSound attenuation of the diffuser ΔL from duct to room,including end reflection, see table below
BalancingBalancing data is contained in a separate brochure.
Throw l0.2The throw is specified at a terminal velocity of 0.2 m/s.
Air jet distributionlb = Distance from the diffuser to the point where there is
maximum dispersal.bv = Depth of the air jet on a vertical plane.bh = Width of the air jet on a horizontal plane.
Minimum pt=50 Pa pt=50 Pa
