Comes with one elbow. \n \n76" Height with ducts. \n \nA single phase motor on the tube axial fan. \n \nThis fan recirculates the air.It pulls the air out of the evaporator and pushes it into the Companion. \n \nThe Companion has a bigradiator (coil) in it and will need to be fed with cool water 80 deg F or colder, cooling tower orchiller etc. \n \nThe coil will cool the air and condense distilled water out of the air for reuse. \n \nThe cool dry air goes back to the Evaporator to get wet again.  A closed loop air system. \n \nTested.
