Mid-size equipment is the backbone of every fire department, from EMT vehicles to hook and ladder trucks. The 2007 ISC is the best power for this equipment, designed to run stronger than ever with exceptional dependability. Not only does it have more powerful performance, it is quiet, making communications in the cab easier.

The totally integrated ISC design includes our proven cooled-EGR subsystem, a High Pressure Common Rail fuel injection system, patented VG Turbo, Cummins Particulate Filter and a crankcase ventilation system. Add the optional compression brake, and it even stops better with more than 330 braking hp.

And that's just the start of all the features the ISC has to help your fire and emergency vehicles on call, every minute of every day.

The ISC is also designed to keep operating costs in check, with long maintenance intervals and excellent fuel economy. Ratings range from 260-360 hp.

Heavy-duty components such as articulated-steel-top pistons and roller camshaft followers are standard, along with a self-tensioning belt drive system to increase belt life. A high-efficiency lube cooler lowers oil temperatures and improves lubrication. Put all that together with Six Sigma design practices, and you've got an engine that is built to run long and strong, in every type of fire apparatus and emergency vehicle.
