I-engeli yokufafaza yombhobho wesigaxa esingenalutho ngu-52 ° -180 °. I-engeli yesifutho ihlukaniswe nge-engeli ejwayelekile ne-engeli ebanzi. I-engeli ejwayelekile ibhekisa emgodini wesigaxa esingenalutho nge-spray angle engaphansi kuka-80 °, kanti i-engeli ebanzi ibhekisa kusigaxa esingenalutho nge-engeli yesifutho esingaphezu kuka-80 °. umlomo wombhobho.

I-standard-angle hole hole eyisigaxa ngokuvamile isebenzisa ukwakheka kombhobho oyindilinga, futhi i-engeli yokufafaza ilawulwa ukujikeleza kuketshezi okubangelwa umgodi wombhobho. Ibhuloho lesigaxa esibanzi le-engeli ebanzi lisuselwa emgodini wombhobho oyindilinga futhi lenyusa ukuphambukiswa Lapho uketshezi lufuthwa ngemuva kokujikeleza ngesivinini esikhulu, luzofuthwa eduze kwendawo yomhlahlandlela, ngakho-ke i-engeli yendawo yomhlahlandlela inquma okokugcina i-engeli yokufafaza yombhobho wesigaxa esingenalutho.
