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.
