Izici zokufaka nokukhipha ze-vacuum booster. Kukhona iphuzu lokushintshashintsha ku-curve ngayinye ehambisana namadigri ahlukene e-vacuum esithombeni, esibizwa ngokuthi iphuzu lokusiza ngamandla amakhulu, okungukuthi, iphuzu lapho umehluko wokucindezela osebenza ku-servo diaphragm ufinyelela khona esiphezulu njengoba amandla okufaka ekhuphuka. Kusukela kuleli phuzu kuqhubeke, ukwanda kwamandla okukhiphayo kulingana nokwanda kwamandla okufaka.
Ngokusho kwe-QC/T307-1999 "Izimo Zobuchwepheshe ze-vacuum Booster", izinga le-vacuum lomthombo we-vacuum ngesikhathi sokuhlolwa lingu-66.7±1.3kPa (500±10mmHg). Izici zokufaka nezokukhipha ze-vacuum booster zinqunywa kuqala ngendlela yokubala. Ngokusho komgomo wokusebenza we-vacuum booster, amapharamitha amabili ahlukile ku-characteristic curve angalinganiswa: amandla okufaka ahambisana ne-maximum power point kanye ne-sum; Isilinganiso samandla okukhipha ku-input force ngaphambi kwe-maximum power point, okungukuthi isilinganiso samandla.
