Why we love it
  • Durable high-strength steel construction.
  • Effective sound insulation feature.

Main Highlights
  • High quality: Made of high-temperature galvanized steel plates, both the inner and outer surfaces are treated with high-temperature baking paint to prevent rust. Our generator enclosure is specially designed to protect your generator.Internal space: 39.4" x 35" x 35.5" (suitable for most generators within 15,000 watts).It features simple and convenient installation – the generator can be easily placed inside without complicated operations.
  • Sound insulation and drainage design: the top of generator shell is filled with high-density fire-proof sound-absorbing cotton, which can effectively absorb generator noise. The air inlet and the air outlet are designed in a double-layer structure, which effectively blocks the spread of noise and isolates the rain from entering. The bottom of the air inlet is all designed with multiple water outlet holes, so that accidental water inflow can be eliminated in time to protect the reliable operation of the generator
  • Adapt to all kinds of weather conditions: it can be used normally in all kinds of extreme weather, whether it is hot or cold, and it can easily resist the heavy pressure of ice and snow. When heavy rain and hurricane come, it can effectively protect the generator from normal use. The whole box surface is treated with metal paint, which has very good outdoor weather resistance
  • Protect the generator: multiple air inlets are evenly distributed on the outside of the box, which reasonably realizes the comprehensive ventilation and heat dissipation of all parts of the generator, forms good air convection, and is equipped with high-quality metal exhaust fan with high and low temperature resistance Operation window: there is an operation window on the front of the generator static speaker, so it is convenient to start, stop and monitor the generator without opening the upper cover of the outer box. Our generator storage box is equipped with a solid lock, which effectively prevents unauthorized personnel from opening the outer box
  • Generator exhaust port: the generator exhaust pipe should be connected to any one of the exhaust gas outlets during the use of the generator case (a stainless steel exhaust pipe is arranged in the package to connect the generator exhaust pipe). Note: Box A and Box B are combined into a box assembly
