Internal fan alternator cuts weight, boosts output

Prestolite Electric's AVi2800 internal fan alternators now offer 190-amp output in a package that is 33% lighter than previous models. The unit features a streamlined internal fan to optimize cooling capability and expand its temperature rating to +125°C.


The AVi2800 internal fan alternator is ideal for high-performance aftermarket retrofit upgrades, particularly within older model school buses and heavy trucks, or in applications where weight reduction, higher temperature and higher power are target goals.

The additional 30-amp output provides substantially more power at idle.

The units are also remote-sensing capable, ground isolated and e-coated for enhanced protection from corrosion, humidity and moisture. They are easily installed via positive and negative wire connections, and feature industry standard SAE pad and J180 mounting configurations.

Quantities of the new AVi2800 are now available for immediate customer order as “A” stock from the company’s Florence, Kentucky-based distribution center.
