FW Murphy - Model Rich-Burn-AFR-9R - Air/Fuel Ratio Control System- Brochure

The AFR-9R is the right choice when searching for the simplest to use load following air/fuel ratio control system. The system is designed to maximize the efficiency of a three-way catalyst by maintaining the proper air/fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressure. This is done without operator intervention after the initial program setup.
