Ibhokisi yesiphambuka ye-MG engangeni manzi ubukhulu be-400× 300× Izixhobo ze-180 zenzelwe ukubonelela ngoqhagamshelwano olukhuselekileyo lombane phantsi kweemeko ezahlukeneyo zokusingqongileyo. Le bhokisi yokuhlangana inomsebenzi wokungangeni manzi, enokukhusela iingcingo zangaphakathi kunye namalungu ombane ekufuma, kumanzi emvula, okanye kwezinye izinto ezingamanzi.
Uluhlu lwe-MG lwebhokisi ye-junction engangeni manzi yenziwe ngezinto ezikumgangatho ophezulu, ezinokuqina okuhle kunye nokumelana nokubola. Ubungakanani bayo obubambeneyo buyenza ilungele ukufakwa kwiindawo ezilinganiselweyo, ezinje ngeebhilibhodi zangaphandle, iigaraji, iifektri kunye nezinye iindawo. Ukongezelela, ibhokisi ye-junction nayo inomsebenzi wothuli, onokuthi uthintele ngokufanelekileyo uthuli kunye nezinye iinqununu ukuba zingene ngaphakathi, ziqinisekisa ukuzinza nokuthembeka koxhumo lombane.
