Industrial Induced Draft Fan for Boiler and Flue Gas Exhaust Systems

Product Introduction

The GY6-41 centrifugal induced draft fan is developed for industrial systems that require continuous exhaust of combustion gas, smoke and dusty air.

It is commonly installed in boiler systems, dust removal equipment, industrial furnaces and flue gas treatment processes where stable airflow and reliable pressure performance are required.

Unlike ordinary ventilation fans, an induced draft fan works under negative pressure conditions to remove exhaust gases and maintain proper operating conditions inside industrial equipment.

SIMO provides customized fan solutions according to airflow, pressure, temperature, gas characteristics and installation requirements.

Technical data

Why Industries Use Induced Draft Fans?
