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.
