Heavy Duty Stainless Steel Primary Air Centrifugal Fan for Industrial Boiler Systems

Introduction

This heavy-duty primary air centrifugal fan is designed for industrial boiler systems requiring stable airflow, medium-high pressure, and continuous operation.

The fan supports fuel drying, combustion air transportation, and airflow balancing in boiler systems. Its stainless steel and heavy-duty structural design helps maintain reliable performance in dusty, high-temperature, and demanding industrial environments.

It is widely used in power plants, industrial steam boilers, circulating fluidized bed systems, and industrial combustion projects.

Key Features

• Heavy Duty Structural Design – Suitable for continuous industrial boiler operation
• Primary Air System Matching – Supports fuel conveying and combustion airflow
• Stainless Steel Configuration Available – Suitable for humid and corrosive conditions
• Stable Medium-High Pressure Performance – Designed for resistant duct systems
• Flexible Drive Options – Belt, coupling, and direct drive available

Technical data

Advantages and Features

1. When the pressure requirement is met, a large gas flow can be output, and the noise is very low.

2. The fan speed can be flexibly set by matching different diameters of belt pulley to make the fan run at the highest efficiency point and reduce energy waste.

3. Motor sliding guides are provided for easy tensioning of the belt to reduce energy loss due to belt slack.

4. When the airflow resistance is increased, the motor load will be automatically reduced and the motor will not be burnt.

5. In the case of a monolithic bracket, the installation is very simple and requires little support from a professional technician.

6. After the production is completed, all products are tested for running and vibration values for reliable operation.
