Compliance AFR-FI



compliance controls AFR-FI air fuel ratio controller

Compliance Controls AFR-FI air/fuel ratio controller is your best value for fuel injected, lean-burn natural gas engines. What do you get with the microprocessor-based AFR-FI?

Fuel Efficiency

No more traditional pneumatics. The AFR-FI is a "smart system" that automatically optimizes the lean-burn air-fuel mix to ensure top performance and fuel efficiency.

Lower Maintenance

The AFR-FI delivers optimized engine operation and stays alert with 26 alarms and shutdowns - covering fuel flow and fuel pressure, intake manifold temperature, exhaust temperature and air manifold pressure. Other AFR's for lean-burn, fuel-injected engines deliver a whole lot less. But the AFR-FI, with easy installation, automatic operation and state-of-the-art technology, is simply the best value you can find.

Automated Compliance

The AFR-FI maintains tight control of the lean-burn air-fuel mix with computer speed and precision.
