Helitaanka faakuumka waxa kale oo loo yaqaan "vacuum pumping", taas oo loola jeedo isticmaalka bambooyinka faakuumka ee kala duwan si looga saaro hawada gudaha weelka, si cadaadiska meesha bannaan uu hoos ugu dhaco hal jawi. Waqtigan xaadirka ah, si loo helo faakuumka iyo aaladaha sida caadiga ah loo isticmaalo oo ay ku jiraan bambooyin vacuum ah oo rotary vane ah, bambooyin xididdada, bambooyin saliid faafin ah, bambooyin molecular oo isku dhafan, bambooyin shaandho molecular ah, bambooyin sublimation titanium, bambooyin ion ah iyo bambooyin cryogenic iyo wixii la mid ah. Matooradan, afarta matoob ee ugu horreeya waxa loo kala saaraa sida gaaska wareejinta (transfer vacuum pumps), taas oo macnaheedu yahay in molecules gaaska si joogto ah loogu nuugo bamka vacuumka oo lagu sii daayo deegaanka dibadda si loo xaqiijiyo daad-gureynta; Afarta bambooyin ee ugu dambeeya waxa loo kala saaraa sida matoorada gaaska qabashada (capture vacuum pumps), kuwaas oo molecularly condensed ama kiimiko ahaan ku xidhan gidaarka gudaha ee qolka bamgaraynta si ay u helaan faakuumkii loo baahnaa. Matoorada gaaska-qaadista waxaa sidoo kale loo yaqaan bambooyinka faakuumka ee aan saliidda lahayn sababtoo ah saliid uma isticmaalaan dhexdhexaad shaqo. Si ka duwan bambooyinka wareejinta, kuwaas oo si joogto ah u saara gaaska, qaar ka mid ah bambooyinka qabashada ayaa dib loo rogi karaa, taas oo u oggolaanaysa gaaska la ururiyey ama cufan in dib loogu sii daayo nidaamka inta lagu jiro habka kuleylka.
Matoorada vacuum wareejinta waxay u qaybsan yihiin laba qaybood oo waaweyn: wareejinta mugga iyo xawaaraha. Matoorada wareejinta mugga sida caadiga ah waxaa ka mid ah bambooyin farsamo oo wareeg ah, matoorada giraanta dareeraha ah, bambooyin is-beddel ah iyo bambooyin xidid; Matoobadaha faakuumka wareejinta sida caadiga ah waxaa ka mid ah bambooyin molecular, matoorada jet-ka, matoorada faafinta saliidda. Qabashada bambooyin vacuum sida caadiga ah waxaa ka mid ah adsorption heerkulka hoose iyo bambooyin ion.
Guud ahaan, habka daahan waa ka duwan yahay, vacuum daahan qolka vacuum waa in ay gaaraan heerar kala duwan, iyo in technology vacuum, in ka badan in vacuum asalka (sidoo kale loo yaqaan vacuum gudaha) si ay u muujiyaan heerka ay. Faakuumka asalka ahi waxa loola jeedaa faakuumka qolka dahaarka faakuumka iyada oo loo marayo bamka faakuumka si loo daboolo baahiyaha habka daahan ee faakuumka ugu sarreeya, iyo cabbirka faakuumkan, inta badan waxay ku xidhan tahay awoodda bamgaraynta faakuumka. Qolka dahaarka faakuumka habka faakuumka vacuum wuxuu gaari karaa faakuumka ugu sarreeya waxa loo yaqaan xadka vacuum (ama xaddid cadaadiska). Jadwalka 1-2 wuxuu taxayaa kala duwanaanshaha cadaadiska shaqada ee qaar ka mid ah matoorada faakuumka caadiga ah iyo cadaadiska ugu dambeeya ee la heli karo. Qaybaha hadhka leh ee miiska waxay u taagan yihiin cadaadiska uu heli karo bamka faakuumka kasta marka lagu daro qalabka kale.
