Vacuum girazi iri mhando nyowani yegirazi yakadzika yekugadzirisa chigadzirwa, iyo yakagadzirwa zvichibva pane iyo nheyo yeTermosa bhodhoro. Chimiro chegiruum yegirazi chakafanana nehombodo yegirazi, mutsauko ndewekuti gasi mune iyo vacuum girazi cavity iri kutetepa zvakanyanya, pedyo nekuvhara.

Girazi reVaCuum ndeyekusimbisa zvidimbu zviviri zvegirazi rakatenderedza, iyo gomba regirazi riri kuita chimwe chidimbu cheGirazi Nheyo dzayo dzekushanda dzakafanana neiyo inopisa misimboti yegirazi Arermos bhodhoro. Vacuum girazi ndiyo michero yegirazi tekinoroji uye Science Science, Scuum Technology, Yemanyorerwo Autchation uye neyekuvaka, matekiniki akasiyana siyana, tekinoroji akasiyana siyana, kushandira pamwe kwakasiyana-siyana.
