TSC terminal unit is composed of:.
· Casing in galvanized steel (TSC) internally insulated with high density material, protected on the air flowsurface,inordertoavoiderosionandscaling.
·Deviceproperfortheairflowadjustament.

The air distribution is made using round or square diffusers (supplyloose);theairflowregulationismadebymeansofa manual rotation of a knob in the diffuser. (See “Diffuser for Air Terminal Units” brochure).

SOUND ATTENUATION
Inside rooms or cabins, it is necessary to grant a well defined level of sound pressure LP (ref.2*10-5Pa).
Ls, obviously depending from Lw (see charts), is equal to the logarithmic sum of the direct sound pressure level andreflexsoundpressurelevel.
Lp=Lpd + Lpr
