several factories, central tank is not installed
or can't be installed because of the problem
caused by insufficient space or various types
of cutting oil.
In this case, ozone sterilizer is installed
by the side of each metal processing machine
Contaminated cutting oil is adsorbed by
adsorption pump installed in sterilizer
and then it is supplied to small-sized sterilizing
chamber Adsorbed cutting oil is sprayed
with ozone in sterilizing chamber.
In the facility, adsorption pump, sterilizing
chamber and ozone generator operates like
the facility attached to machine tool.
