This particular item is upgraded with a poly-carbonate material for adverse, high heat conditions and is offered for the same price as currently listed.  The material is also black and can withstand a temperature of 240 F.  Please visit www.generator-line.com for more information. The Generator-Line enclosure exhaust system will allow the EU2000i, EU3000is, or EU6500is generator to be operated enclosed for weather protection, security, and additional sound reduction by allowing the emission of the cooling air and exhaust.  The EU2000i and EU3000is directional cooling is from front to rear, drawing air from the control panel side and exiting at the opposite side.  Note the vent at the top of the control panel on the EU2000i which is the cooling air intake.  The series of vents at the bottom of the control panel on the EU3000is provide the same function.  The flexible, expandable aluminum tube captures both the exhaust and cooling air on the EU2000i and EU3000is.  The EU6500is kit has a seperate flexible pipe and adapter for the exhaust only.  The exhaust attachment may be purchased separately for the EU6500is (see website).  The rear top vent emits heated cooling air only. The exhaust systems prevent the recirculation of hot exhaust and engine cooling air by emitting them to the outside of the generator enclosure. WARNING!  Exhaust fumes can kill you in minutes! The Generator-Line LLC enclosure exhaust is not for the use of the generator in or near living areas such as attached garages, recreational vehicles, and basements, etc.  

Generator-Line is considering the developement of an exhaust for the EU3000i "Handi" and Yamaha EF3000is.  We would like to know of your interest.  Please send us a message regarding if you own these generators, or are considering the purchase, and would need an exhaust system for it.
