  • No Clogging / Choking


Vacuum tubes assimilate the advanced 12 years of spattering deposition of trivalent element technology, high borosilicate glass, gradual change of CU - AL - N / SS selective complex absorptive coating. And these make vacuum tubes having high performance of absorptance and low reflection ratio.

Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380° C of idle sunning, performing a strong heating ability.
