Variable air volume controllers
Rectangular silencer Optima-SA designed to fit directly
to Optima-RS VAV terminal units. The inlet and outlet
connection is designed to effectively and easily be
mounted to the Optima-RS units.
The Optima-SA effectively reduces noise levels on the
discharge of the VAV unit. Two silencers can be used in
series together in installations where noise reduction
is a particularly strong requirement, this can be very
effective. For the most effective noise reduction, the
silencer should be fitted immediately downstream of the
VAV terminal unit and before the accessories such as
Optima-RS-MO (Rectangular to round Multi-outlet units)
or after the Accessories such as VBR (Water Batteries).
The silencer is delivered in fixed length of 1000mm and
is insulated with thicknesses which vary to assure highest
attenuation possible without compromising an increase in
the pressure loss.
