Lesi sithando somlilo silungele ukuncibilika kwensimbi ku-vacuum ngesimiso sokushisa sokungenisa imvamisa emaphakathi, sisetshenziselwa kabanzi ukuncibilikisa nokuphonsa ingxubevange yensimbi noma insimbi ehlanzekile ku-vacuum.Umthamo usukela ku-3-5KG iqoqo ngalinye.

Uhlelo luqukethe isitsha somlilo, isistimu ye-vacuum, kanye nesistimu yokulawula kagesi, isistimu yokulawula i-vacuum, isistimu yokushisa ye-IF, uhlelo lokuthulula nokukhipha.Lolu cingo luyithuluzi lokuncibilikisa lokushisisa imvamisa emaphakathi.Isithando somlilo sinekhoyili yeshubhu elivunguzayo ngaphakathi, lapho ikhoyili idlula imvamisa yamanje yamaphakathi, inkambu kazibuthe eshintshanayo ikhiqizwa.Insimbi izoncibilika endaweni kazibuthe.
