Carbon Steel Medium Pressure Anti-Explosion Centrifugal Fan for Chemical Plant Gas Delivery
carbon steel centrifugal fan
,medium pressure explosion-proof fan
,chemical plant gas delivery fan
The 7-09 series medium pressure centrifugal fan delivers moderate pressure and large flow capacity, belonging to the low noise series with stable performance characteristics.
Suitable for conveying normal temperature or high temperature non-flammable gases (normal air, high temperature gas, corrosive gas, dusty gas), and transporting granular/powder/chip/fiber materials.
This widely used medium-pressure heavy-duty centrifugal fan is commonly employed in industrial systems including boilers, dust collectors, desulfurization systems, cement, chemicals, metallurgy, electric power, and gas/material transportation applications. Also suitable for general ventilation purposes.
- Delivers higher outlet pressure and increased gas flow with lower noise levels. Maintains stable operation at elevated media temperatures.
- Custom-designed according to customer performance requirements, optimized through CFD technology for lower energy consumption compared to similar models.
- Multiple optimizations of airflow channel and impeller design result in higher efficiency and energy savings compared to standard large-flow fans.
- Impeller and main shaft materials selected from high-strength carbon steel, low-alloy steel, high-temperature alloy steel, or high temperature resistant high-strength alloy steel based on working conditions and speed requirements.
- Specialized treatments for dust-containing gases extend impeller life by over 3 times, with surface hardness reaching HRC60-70.
