Connection between the suction duct and the extraction fan
:
The
KPC
connection (of the
KOS-AL

of conduits and fitting pieces type SPIRO spiral-seam duct. The diameters of these elements
should match the assumed duct connections.
It is recommended:

before the fan inlet
– the silencer length ought to be not less

plication
– on wall brackets.
