10. Piping
(1)
Duct hose material
Because the life of the duct hose will vary according to the type of mist
being sucked in, the use of an oil-resistant duct hose is recommended.
(2) Intake duct piping
①
A flexible duct (optional item) should be used to facilitate easy duct
maintenance and vibration resistance.
②
The duct should be somewhat longer than strictly necessary (slight
length surplus), but it must not sag when connected.
③
Use the duct companion flange (accessory item) to facilitate easy
connection.
④
Positioning the intake port too close
to the mist generation source could
result in large amounts of mist,
cutting chips, and dust to be sucked
in, causing blow leakage and
accelerated clogging of the filters and
demister. Either provide an adequate
distance (approx. 500mm) between
the mist generation source and the
intake port, or install an impact plate
to prevent clogging from sucked-in
mist, cutting chips, and dust.
