What the variable-speed blower does
The variable-speed blower can run at lower speeds for gentler airflow and ramp up as the system calls for more. The ML180 is single-stage on the burner side. The ML296, EL297, SL280, and SL297 are two-stage. Check each product page for AFUE and cabinet width, then match the evaporator coil to that width.
