Urukurikirane rwa KQ2D pneumatike imwe kanda umuyoboro wumuyaga ni umuhuza mwiza kandi woroshye uhuza imiyoboro yumuyaga muri sisitemu ya pneumatike. Ihuza ifata igitsina gabo cyihuta cyihuta, gishobora guhuza byihuse kandi bihamye umuyoboro wumwuka, bigatuma gazi itemba neza kandi idakumirwa.
Ihuza rifite ibiranga kuba byoroshye kandi byoroshye gukoresha, kandi birashobora guhuzwa nigikoresho cyoroheje gusa bidakenewe ibikoresho byinyongera. Ihuza ryizewe ryemeza ko trachea ihujwe idacika intege cyangwa ngo igwe, bitezimbere imikorere yumutekano n'umutekano.
Ibikoresho bya seriveri ya KQ2D ni umuringa, ufite imbaraga zo kurwanya ruswa kandi ukarwanya ubushyuhe bwinshi, kandi ukwiranye n’ibikorwa bitandukanye bikaze. Igishushanyo cyacyo kiroroshye, cyoroshye mubunini, kandi byoroshye gushiraho no gukoresha.
