Air Fuel Ratio Controls (9R)
Air Fuel Ratio Controls (9R)


Compliance Controls' AFR-1R air/fuel ratio controller is exactly the right choice. It's pure simplicity at every step - from installation to operation.


Compliance Control's AFR-9R air/fuel ratio controller offers the same simplicity as the AFR-1R model such as non-intrusive installation and streamlined menu-driven navigation, but with more setpoints, you get even tighter control.


The AFR-9R controller offers nine setpoint targets, based on a combination of three RPM settings and three manifold pressure settings. As your engine's load conditions change, your AFR-9R continues to make sure it is in the best possible operating range for optimum catalyst performance.


If your site is facing tightening regulations, changes in ambient temperature, big load swings or gas quality/pressure changes, the AFR-9R is the right choice. It's simple air/fuel ratio control with more flexibility.


The AFR-9R air/fuel ratio controller is a true load-following controller (measuring manifold pressure and RPM). It features nine air/fuel setpoints that can be specifically matched to engine conditions.



  • Simplest multipoint air/fuel controller on the market
  • Easy on-screen interface for convenient setup and operation
  • Nine air/fuel setpoints matched to specific engine load conditions
  • Operator help key on display



  • Designed for applications with varying engine loads
  • Ongoing compliance in high-variable environments
  • Fast and easy installation
  • Minimal operator training required
  • Comprehensive fault diagnostics
  • Fully automatic - no operator required in normal operation
  • Nine setpoints - better resolution and control of load swings
