Features of Duromax XP4000S Portable Generator

  • Air-cooled engine – this generator features a durable Durostar 7.0 HP air cooled OHV engine with excellent w/low oil shut off. This enhances the life span of the engine because anytime it gets hot, it cools itself using air. It is designed to easily maintain itself so that the engine continues running in the right condition.

Because its motors are separated, it allows you to have smooth operations thus making it the best generator for you.

All these outstanding features make it very convenient to use and also enhance its functionality.
