We're Xinxiang SIMO Blower — 70 years building centrifugal fans. Every step, from impeller pressing and dynamic balancing to final inspection, happens in our own factory. One customer ran our fan for 18 months straight with zero unplanned shutdowns.
Most industrial boilers use Balanced Draft — a forced draft fan pushes air in while an induced draft fan pulls flue gas out. Furnace pressure stays stable, combustion stays optimized.
For small oil or gas boilers, Forced Draft alone does the job — fan at the front, pushing air in.
For large coal-fired boilers with massive flue gas volume, Induced Draft is the answer — fan at the back, pulling exhaust out.
