The Y6-30-12 is a C-type boiler induced draft fan series documented for No.3.5C through No.8.6C. It is mainly used in the induced-draft systems of small boilers and packaged boilers.
The original catalogue provides performance, motor, boiler-capacity reference and installation data for the complete documented range, including outlet-position drawings for multiple fan sizes.
Catalogue reference condition: inlet gas temperature 20°C, atmospheric pressure 101325 Pa and gas density 0.745 kg/m³.
Documented Boiler ID Fan for Small and Packaged Boiler Systems
The original catalogue identifies Y6-30-12 for induced-draft systems of small boilers and packaged boilers. Other conditions with similar performance requirements may also be reviewed.
Unlike the Y6-30 series overview page, this page carries documented model-level performance data, size coverage, motor references and installation drawings.

Performance Summary by Fan Size
The table below condenses the original catalogue into model-level operating ranges. Final selection should still use the exact duty point within the relevant model row.

Select From Airflow and Pressure, Then Check the Boiler Condition
Required Airflow
Use the actual boiler exhaust airflow, not boiler tonnage alone.
Required Pressure
Account for boiler, flue duct, dust collector, damper and chimney resistance.
Gas Condition
Confirm inlet temperature, gas density, dust loading and any corrosive or abrasive condition.
Outlet Position
Match the documented discharge orientation to the project duct route.
Motor Supply
Confirm voltage and frequency for the destination market before quotation.
Installation Interface
Check inlet, outlet, foundation, motor-rail and maintenance-space requirements.
If system pressure is unknown, use the Static Pressure Unknown Guide.
Boiler Induced-Draft Duties Covered by Y6-30-12
Small Boiler Induced Draft
The primary application stated in the original catalogue.
Packaged Boiler Exhaust
Suitable for packaged-boiler induced-draft systems within the documented performance range.
Dust-Collector Exhaust Support
Selection can include resistance from a cyclone, filter or other flue-gas cleaning equipment.
Existing Fan Replacement
Old nameplate, photos, pulley data, motor data and dimensions can be used for replacement review.
