FFDM
Damping pad
FFDM - The damping pad is used to restrict the transfer of dynamic forces created by fan vibrations, units and potentially other equipment on the attached HVAC piping and their transfer back of forces caused by vibration, expansion or mass.
Properties
•The damping pad is used to restrict the transfer of dynamic forces created by fan vibrations from units
•Pads are determined for ducts in Group 1
•tightness class ATC 2
•Width of pad flange 20 mm or 30 mm
•Round or square shape
•design galvanized or stainless steel (AISI 304)
Specifications
The damping pads (hereinafter the pads only) are used to prevent the transmission of dynamic forces caused by vibrations of fans, units or other devices to the connected ventilation ducts and their returning transmission of forces caused by vibration, dilatation or weight.
