Tips: Backward and forward curved centrifugal fan applications

Backward and forward curved centrifugal fans are crucial in HVAC systems, industrial processes, and air pollution control due to their distinct characteristics.

Backward inclined centrifugal fans are known for their high efficiency and low noise levels, making them ideal for clean air applications such as ventilation, air conditioning, and cooling systems in industrial settings. They can handle high pressures and are often used in situations where energy efficiency is paramount, like in clean rooms, data centers, and large commercial buildings.

Forward curved centrifugal fans are suited for low-pressure, high-volume applications. Their compact design makes them ideal for residential HVAC systems, small exhaust systems, and air handling units. They are effective in situations where a continuous flow of air is required, such as in heating systems, kitchen exhausts, and automotive ventilation.

Both types are essential in maintaining air quality, ensuring proper ventilation, and supporting various industrial processes by moving air efficiently.

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.
