Airquest RGF Rooftop Units

3, 4, 5 AND 6 TON UNITS
SINGLE-PACKAGED ROOFTOP
GAS HEAT/ELECTRIC COOLING WITH R-454B REFRIGERANT

RGF units are single-packaged electric cooling, gas heating rooftops. All units are pre-wired and pre-charged with new, low global warming potential R-454B refrigerant. R-454B represents a 75% reduction in refrigerant GWP over legacy R-410A models. All units are factory tested in both heating and cooling modes. 3-5 ton models use single stage cooling capacity control. 6 ton models use two-stage cooling capacity control.
