Tips: DC backward curved centrifugal fan working principle

A DC backward inclined centrifugal fan operates on the principle of converting rotational energy into airflow. The fan consists of a rotating impeller with backward-curved blades. When the impeller spins, it draws air into the fan through the inlet. The backward-curved blades are designed to guide the air in a radial direction, accelerating it outward towards the fan's discharge.

The backward curve shape helps in achieving higher efficiency and lower noise levels compared to forward-curved fans. As the air is forced out of the impeller, it gains velocity and pressure, creating a continuous flow of air. The DC motor driving the fan provides precise control over speed and power consumption, allowing for efficient operation and adaptability in various applications. This design is commonly used in ventilation systems and air handling units where energy efficiency and low noise are critical.

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.
