The suction power of Hakko fume extractors varies depending on the specific model. Generally, Hakko offers a range of fume extraction systems designed for different applications, from small-scale soldering stations to larger industrial setups. 
For instance, the Hakko FA-400, a popular bench-top smoke absorber, has a suction capacity of approximately 1.07 cubic meters per minute (37.8 cubic feet per minute) when used in the upright position. This model is suitable for light-duty applications and is often used in electronics assembly and repair.
On the other hand, the Hakko FA-430, a more advanced fume extraction system, is designed for more demanding environments. It features a high-performance fan and a three-stage filter system, providing a maximum airflow of about 4.7 cubic meters per minute (166 cubic feet per minute). This model is ideal for environments where multiple workstations require fume extraction or where more hazardous fumes are present.
For industrial applications, Hakko offers models like the HJ3100, which can provide even greater suction power and airflow to accommodate larger workspaces and more intensive fume extraction needs.
It's important to note that the actual suction power experienced can be influenced by factors such as the length and diameter of the ducting used, the type of filters installed, and the specific setup of the work environment. Users should consult the product specifications and manuals for precise details on each model's capabilities and ensure that the chosen fume extractor meets the specific requirements of their application.
