1. The MegaStar uses individual control motors directly coupled for each fuel control valve.
The optional remote rack mounted fuel manifold includes a separate control motor for the
fuel control valves, which is electronically linked to the air control. Air control is performed
with a VFD, modulating the output frequency between 16 Hz and 60 Hz to achieve a precise
air flow.
