Ny boka mifehy ny pneumatic dia ampiasaina amin'ny simika, solika, metallurgy, hery herinaratra ary sehatra indostria hafa ho an'ny fitsipika sy fifehezana ny tsiranoka sy ny fifehezana ny tsiranoka sy ny fifehezana ny tsiranoka. Mety hahatratra ny fifehezana tsara ny fikorianan-javatra sy hiantohana ny fahamarinan-toerana sy ny fahatokisana ny fizotrany.
Toetoetra:
1. Ny fahatokisana avo : ny bellows pneumatic mifehy ny valve dia vita amin'ny fitaovana avo lenta, dia manana fanoherana tsara sy fanoherana ny mari-pana ary ny fanoherana ny mari-pana, ary mety haharitra mandritra ny fotoana maharitra.
2. Fikojakojana mora : Ny bela-boninkazo mifehy ny pneumatic dia manana rafitra tsotra ary mora ny mitazona ny fotoana sy ny vidin'ny fikojakojana sy ny vidiny.
3. Fampiharana malalaka : Ny famerenam-bolo dia mety amin'ny rafitra fanaraha-maso tsiranoka ao amin'ny indostrian'ny simika, solika, herinaratra, metallurgy ary saha hafa, ary afaka mahafeno ny fepetra takian'ny toe-javatra isan-karazany.
Ny vokatra lehibe ataon'ny orinasa dia misy valve fanaraha-bazana pnematic, valve ball pnematic, valve control elektrika, fluorine voditongotra valve, precession vortex flummeter, goavambe.
