Always observe local building codes.
Description
Trade-Wind® Fast Clamps are designed to isolate and absorb motor vibration noise transmitted by the walls of the
duct with a 3/8” neoprene lining. In addition, the Fast Clamps secure the ventilation duct to the in-line blower, duct
silencer or damper.
Installation Details
Fast Clamps are packaged two per box. For best sound reduction, install one on each side of the blower. Position
the end of the metal duct pipe approximately ¼” from the end of the blower’s vent collar. In order to minimize
vibration, the blower collar should not touch the metal duct on either end. Tighten the two adjustment screws until
the fan and the duct are securely attached.
IMPORTANT: The Fast Clamp must also be attached to the blower collar with 3 or 4 equally spaced sheet-metal
screws and duct tape. Without the additional sheet-metal screws and duct tape, the in-line blower may
unintentionally separate from the Fast Clamps. To reduce the possibility of vibration noise, it is best to NOT screw
the Fast Clamp to the duct pipe, only to the blower. Placing sheet metal screws through the blower side of the Fast
Clamp AND the duct side of the Fast Clamp will create metal-to-metal contact that will transfer vibration noise. The
Fast Clamp should be attached to the duct pipe with duct tape only.
Trade-Wind® Fast Clamps are equipped with integral hanging tabs. DO NOT hang the blower mechanism from
these tabs on the Fast Clamps (these tabs are not designed to support the weight of the blower mechanism unit.
All Trade-Wind® in-line blowers and most other brand in-line blowers are equipped with the necessary support
brackets to hold their weight.
