Carbon Steel Medium Pressure Anti-Explosion Gas Delivery Centrifugal Fan for Chemical Plant
carbon steel centrifugal fan
,medium pressure explosion-proof fan
,chemical plant gas delivery fan
The 7-09 series medium pressure centrifugal fan has moderate pressure and large flow, belongs to the low noise series fan and has stable performance.
It's suitable for conveying normal temperature or high temperature non-flammable gas (normal air, high temperature gas, corrosive gas, dusty gas), and conveying granule/powder/chip/fiber material.
It's a widely used medium-pressure heavy-duty centrifugal fan, which is commonly used in industrial systems such as boilers, dust collectors, desulfurization systems, cement, chemicals, metallurgy, electric power, and gas and material transportation. It can also be used for general ventilation.
1. It can output higher outlet pressure and provide more gas flow with lower noise. Ability to work stably at higher media temperatures.
2. Customized design according to customer's performance requirements, and optimized by CFD technology, the energy consumption is lower than similar models.
3. The airflow channel and the impeller have been optimized several times, which is more efficient and energy-saving than ordinary large-flow fans.
4. For the material of impeller and main shaft, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature resistant high-strength alloy steel for different working conditions temperature and working speed, so that the impeller and main shaft can still maintain a reliable strength at high temperature.
5. For dust-containing gas, we can meet various working conditions from a small amount of dust to a very large dust content. After special treatment, the surface hardness of the blade can reach HRC60~70, which can extend the life of the impeller by more than 3 times.
