For example, our hydraulic and PTO generators fit into compartments a fraction of the size needed for diesel generators. Our inverter portable line is designed to run smooth and quiet in a compact package. Each of our generators is designed to provide you with reliable power, quiet operation, easy maintenance and compact installation. For maximum power in minimal space, no one quite sizes up to the efficiency of Cummins Onan generators. It's performance you rely on.

Cummins Engines for Fire and Emergency Vehicles

Whether it's a wash-off at a gas station or a four-alarm blaze, it doesn't matter. When the call comes in, you've got to get there in a hurry, and have the power you need to get the situation under control every time.

Cummins engines are designed to run cleanly and quietly, with excellent fuel economy and low maintenance. They use our proven cooled-EGR subsystem, in combination with a proprietary Cummins Particulate Filter.

But it's the combination of superior performance and reliability that makes Cummins your best choice for fire and emergency vehicles. There's the industry-leading, dual-overhead-cam 525-hp ISX. The exceptional power-to-weight ratio of the ISM (365-500 hp). The sophisticated electronics of the ISL (345-425 hp). An ISC with High Pressure Common Rail fuel injection (260-360 hp). And an ISB engine with greater displacement for stronger performance (260-350 hp). Whatever kind of equipment you run, Cummins has an engine with the right power, performance, dependability and durability to meet your needs. All supported by a customer support network that understands the importance of response time.
