California Low-Emission Regulations JetGo Tier 4i low-emission nonroad diesel ground power units are exempt from both California Local Air District permits and the California Airborne Toxic Control Measure for Diesel Particulate Matter. The Kubota engines used are rated at less than 50 Horsepower and are therefore not regulated by California statutes.

Overall pleased with this product. It appears to be very well built, and user friendly. It was delivered fully assembled and ready to go right out of the crate. We are pleased with the safety features, and the cool down function, which will decrease the wear and tear on the engine and generator. This is a fine piece of equipment, and we expect to see years of worry-free service out of it.
