Sirocco Fan has multiple blades, so it operates at low speeds and operates relatively quietly. It is used for large air volume and low static pressure (static pressure 10 to 100 mmAq), and the change in wind pressure due to changes in air volume is small, but the power increases rapidly when operating below the standard specification static pressure.

Wing Shape

• The wings are short and wide: 10mmAq~100mmAq (high air volume, low static pressure)

• The number of wings is greater than other species.

• A centrifugal fan with the end of forward-curved blade bent in the direction of rotation.

Product Feature

• Compared to other models, it has a large air volume and low static pressure structure, so the installation area is small.

• Depending on the impeller shape, it operates at low speeds, resulting in low noise and quiet operation.

• There is little change in wind pressure due to changes in air volume.

• With the installation of Vane Damper, it is easy to adjust air volume and static pressure, making it easy to manage energy efficiently according to position.

• When operating below the standard specification static pressure, the power increases rapidly.

Main Use

• Underground parking lot supply and exhaust, machine room, generator room and electrical room supply and exhaust

• Firefighting smoke control exhaust and supply, kitchen supply and exhaust

• For interior heating and cooling A.H.U., for subway ventilation - Other local ventilation
