Overview

The AL Series Centrifugal Draft Fan is specifically crafted for power station boilers and adaptable to other heavy industries such as metallurgy and chemical processing. Its standout features include:

1.  
2. 1. Optimized Performance with Wide Efficiency Zone: This centrifugal fan is capable of sustaining high efficiency, achieving up to 85% efficiency when fully open, thanks to its flat performance curve and extended high-efficiency range.
3. 2. Simplified Maintenance Access: The casing is designed for segmented assembly, simplifying both transport and installation. Observation points on multiple sides offer convenient entry for inspections and repairs, reducing downtime.
4. 3. Enhanced Noise and Vibration Control: The robust ribbed casing provides stability and can be adapted for noise reduction based on user requirements.
5. 4. Reliable Lubrication System: The outer spherical sliding bearing system operates through oil immersion, removing the need for auxiliary power for lubrication, ensuring continuous operation even during power interruptions.
6. 5. Compact, Space-Saving Design: With its compact construction, the fan requires minimal space, delivering low vibration levels for smooth, reliable functionality in various industrial environments.

Structural Characteristics

1. 1. Types and Flow Control Mechanism: Available in single and double suction designs with a double support structure, the AL Series Centrifugal Fan incorporates a baffle-type inlet damper, controlled by an electric actuator to adjust airflow precisely.
2. 2. Casing with Noise Insulation and Thermal Stability: Designed with soundproofing features, the casing keeps aerodynamic noise under 85dB. It withstands high operational temperatures by maintaining optimal clearances for stable performance across parts.
3. 3. Integrated Main Shaft for Rigidity: The fan’s main shaft is integrally forged with the impeller disc, linked to the motor using a gear coupling, thus reducing weight and simplifying impeller servicing.
4. 4. Durable, Wear-Resistant Impeller: The impeller is specially treated to handle abrasive dust within the airflow, increasing longevity in harsh conditions.
5. 5. Efficient Cooling System: The spherical bearing includes water cooling, keeping the bearing’s operating temperature at a safe level below 75°C, even under intense industrial use.
