DESCRIPTION:
Trade-Wind® Duct Silencers are designed with a perforated lining and diffuser material that provides noise absorption for Trade-Wind® (and
other brands) In-Line and Remote Mount Ventilators. The PSS Duct Silencers are shipped permanently assembled and contain no moving parts
for operation. They can be mounted at any angle.
PLANNING THE INSTALLATION:
Before securing the PSS Duct Silencer, place (or hang) the Duct Silencer on a structurally adequate frame and align with the rigid duct. It is best to
place the Duct Silencer within 2 - 4 feet of the blower / ventilator for maximum noise reduction. DO NOT fasten the Duct Silencer directly to inlet
of the blower / ventilator.Also, MAKE SURE the Duct Silencer is installed at least twice the diameter of the duct away from any elbow.Otherwise,
there will be increased turbulence, which will generate increased noise.

For more information, please contact your dealer or your TRADE-WIND® representative.
CONNECTING THE DUCT SILENCER:
After properly aligning and supporting the Duct Silencer, connect it to the duct. Fasten in place by using sheet metal screws and duct tape or FC
Clamps*.Fast Clamps (FC Clamps) are the recommended connectors for connecting the Duct Silencer and / or blower / ventilator to the duct
system. The clamps have pre-drilled hanging tabs, are easy to connect and work extremely well as a vibration absorber and noise suppressor.
They are made of steel and are lined with a 3/8” neoprene pad. If FC Clamps are used to connect the blower / ventilator to the duct system, it is
not necessary to use them on the Duct Silencer for vibration suppression.
CAUTION: Do not hang “PSD” blower / ventilator models from the FC Clamp’s hanging tabs. Instead, use the integral brackets
built into the blower / ventilator housing.
PSS Duct Silencers weigh more than identical lengths of standard rigid duct. You must adequately support the silencer by hanging or framing. The
Duct Silencer is not designed to serve as support for any piping or loads on the inlet or outlet other than the duct connections.
*FC Clamps are sold separately and are available from Trade-Wind® through your Trade-Wind® supplier.Model numbers FC6 (6”), FC8 (8”) or
FC10 (10”) each have two per box.
