Base Model Kenworth HVAC Box

Our base model, is the most universal among the Kenworth HVAC boxes that we produce. We currently offer two options of this unit the F31-1036SS-1 for heavy-duty W900, T800, T600 etc and the F31-1037SS-1 for your medium-duty T270, T300, T370 etc.

Our base model could be considered our economical option as it comes with less parts than our standard and premium models.
