Tips: Inline centrifugal duct fan working principle

An inline centrifugal duct fan operates based on centrifugal force to move air through ductwork. The fan consists of an impeller housed within a cylindrical casing. When the impeller rotates, it draws air into the center of the fan, or the "eye" of the impeller, through the inlet. The centrifugal force generated by the spinning impeller then accelerates the air outward toward the perimeter of the fan.

As the air is forced outward, it gains velocity and pressure, exiting the impeller at a 90-degree angle to the inlet flow. This high-pressure airflow is then directed into the duct system, allowing it to travel efficiently over long distances. The design ensures a steady and powerful airflow, which is essential for applications requiring consistent ventilation. Additionally, the enclosed design of the fan helps minimize noise and enhances the overall efficiency of the system by reducing energy losses typically associated with axial fans.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
