An Environmentally Friendly Choice for Your Power Generation Needs

The Duromax XP5500EH is fully compliant with both EPA and CARB standards, so it’s legal to use in all 50 states. The engine is designed for both performance and fuel economy, so it produces fewer emissions than other models on the market.

An added feature is the dual-fuel design that allows the operator to use either standard gasoline or propane. Propane costs less than gasoline, burns up to 30% cleaner, and can be stored for extended periods of time. Compare this to gasoline, which can become unstable after just a few months of storage. So using propane makes your generator maintenance checklist a couple of steps shorter.

Another benefit of propane is that 80 to 90% of it is harvested from domestic US sources. This is a great way to help our country reduce its dependence on imported fuel. Also, propane produces fewer toxins and deposits than gasoline, so it’s easier on your generator’s engine as well as the air you breathe.

For maximum portability, we recommend using a standard 20-pound propane tank with your Duromax XP5500EH. Always have it filled at an authorized dealer and follow established safety guidelines. You can also connect your Duromax XP5500EH to larger propane tanks or a permanent fuel line installed by your local utility company. WE DO NOT RECOMMEND USING NATURAL GAS WITH YOUR GENERATOR, as this requires modifications that may compromise its safety or efficiency.

It’s not all upside, though, so see our “propane vs gas generator” article for a review of the pros and cons.
