Company Profile And History Of The Company

Gas-powered, propane-powered, and an innovative dual-fuel (hybrid) type are all available from the Duromax generator series. High accolades have been given to the Duromax brand for cost and dependability. Although DuroPower™ has been producing engines, power equipment, and component components since 1989, the Duromax business has only been around since 2003. This implies that owners of Duromax generators may rely on the decades of expertise the firm has acquired while developing the Duromax generator.

Duromax Offering

The Duromax line, which is a specialty of DuroPower™, provides 20 different generator models with two designs for single, triple, and four-cylinder engines. DuroPowerTM specializes in a range of generators for both residential and commercial usage. Additionally, the product range offers versions that run on gas, propane, and cutting-edge dual fuel (hybrid). These generators are regarded well for price and dependability, and they were made to adhere to the MTL and ETL requirements.
The DuroMax Dual Fuel technology from DuroPower™ enables the generator to run on either gasoline or liquid propane. Compared to gasoline alone, this delivers greater fuel efficiency, cost savings, and longer storage life. Averaging 20 hours on propane and 8 hours on gasoline, Duromax hybrid generators also provide the greatest running time.
Duromax generators put safety first, and DuroPowerTM guarantees safety while the generator is operating. The Low Oil Warning System, which alerts the user when the oil level is low and turns the generator off automatically to avoid engine damage, is a significant feature that distinguishes Duromax from other generators.
The construction of Duromax generators is another crucial factor. Every generator has cast-iron sleeves to shield the engine from knocks, scratches, and hard handling. The Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have both approved Duromax generators as meeting air quality criteria.

With the use of a visual display, this device is intended to alert the user when the oil level in the generator is becoming low. Once the minimal oil level is reached, the generator is subsequently turned off to save you. Your generator will automatically restart when the oil level is topped up, ensuring that it is constantly operating at its peak. This function offers peace of mind and additional generator safety for people who may not be able to regularly check the oil levels in their generators.
