FILTER FOR FLUIDS

摘要

PURPOSE:To efficiently heat a gas by composing a porous filter element with a resistor heat generating body and electrodes attached thereto and heating the filter element. CONSTITUTION:A filter element 5 having fine pores is installed in a line-system of a gas. The filter element 5 is composed of a resistor heat generating body 5 made of a ceramic and a metal and electrodes 6 attached thereto. A gas can thus be heated efficiently by heating the filter element 5 by electrifying the electrodes 6.
