Attach a canvas duct each to the air outlet and air inlet so
that the vibration of the equipment will not be transmitted to
the duct or ceiling.
Use a sound-absorbing material (insulation material) for the
lining of the duct and apply vibration insulation rubber to the
hanging bolts.
r
At the time of duct welding, perform the curing of the duct
so that the sputter will not come in contact with the drain

r If the metal duct passes through a metal lath, wire lath, or
plate of a wooden structure, separate the duct and wall
electrically.
r Be sure to heat insulate the duct for the prevention of dew
condensation. (Material: Glass wool or styrene foam; Thick-
