ʻO ka peʻahi kahe axial no ke kūkulu ʻana i ka tunnel - ʻelua mau kaʻa, ʻelua ʻāpana, ʻano hoʻololi kūʻē 

ʻO nā mea hoʻoheheʻe axial no ke kūkulu ʻana i ka tunnel, 2 * 55kw motors, 2 motors, 2 impellers. Hiki ke hoʻohana ʻia ka peʻahi e lawe i ka ea ma kahi mamao o 1500 mika. Hiki ke hoʻopili ʻia i kahi duct air 1000mm a me kāna kānana ʻeke.

ʻO ka peʻahi kahe axial no ke kūkulu ʻana i ka tunnel: 2 * 55kw motors, 2 motors, 2 impellers. Hiki i ka peʻahi ke lawe i ka ea ma kahi mamao o 1500 mika. ʻO ka mea hoʻoheheʻe axial flow ka hana ʻana i kahi puʻupuʻu suction, kahi muffler inlet, kahi ʻāpana mua, kahi ʻāpana lua, a me kahi muffler puka.
Hoʻokumu ʻia ka ʻāpana peʻahi me kahi paipu makani nui, ka motika, a me ka impeller.
