Documented Boiler ID Fan for Small and Packaged Boiler Systems
The original catalogue identifies Y6-30-12 for induced-draft systems on small boilers and packaged boilers. This product page carries the published model-level performance, motor, boiler-reference and installation information. The boiler-capacity values are catalogue references; final selection should use the project duty point.

Selection Checks for a Boiler Draft Duty
Required airflow and pressure
Confirm actual boiler exhaust airflow and the system resistance through the boiler, flue duct, dust collector, damper and chimney.
Gas condition
Provide inlet temperature, gas density, dust loading and any corrosive or abrasive condition for review.
Outlet and installation
Match the documented discharge orientation, inlet and outlet interfaces, foundation, motor rail and maintenance space to the project layout.
Motor supply
Confirm voltage and frequency for the destination market before quotation.
Typical Applications
Small boiler induced draft
The primary application stated in the catalogue.
Packaged boiler exhaust
Review within the documented airflow and pressure range.
Flue-gas cleaning systems
Include resistance from a cyclone, filter or other dust collection equipment in the duty point.
Existing fan replacement
Share the old nameplate, fan and pulley photos, motor details and installation dimensions for comparison.
Send the Boiler Duty Point
For a quotation review, share model preference, airflow, pressure, boiler capacity, inlet-gas temperature, dust condition, voltage, frequency, discharge orientation, quantity and destination. Unconfirmed engineering details can remain blank.
