Types of centrifugal blower fan Kitchen: airflow along the direction of movement of the fan impeller diameter. Exhaust fan axial fan: airflow along the axial movement of the fan impeller. Greater total pressure centrifugal blower motor isolated from the hot gas fumes. Not easily damaged. Small axial fans, in general, high temperature gas fumes to go through the motor, easily damaged. Kitchen is generally recommended to use a centrifugal fan. Centrifugal fans also points to a multi-leaf front and rear wheel to wheel. Before comparing the advantages of the impeller to the impeller and after :() opt for a lower speed (low noise), smaller diameter can get a larger air volume total pressure. Forward impeller drawbacks: low efficiency, high energy consumption, easy cleaning cleaning. After the impeller advantages: high efficiency, energy saving, easy cleaning cleaning. After drawback compared to the impeller to the impeller) to get the same amount of wind and the total pressure required for high speed (and therefore noisy), and a larger diameter before :(. HTF (A) fire temperature exhaust axial fans characteristics and application HTF (A) fire temperature exhaust axial fan using advanced CAD-aided design system, is the more optimized design of new products developed by the exhaust outlet, with efficiency High curve flat characteristics conducive to energy conservation. Optional molded axial flow impeller, built-in high-temperature motors, arranged a special motor cooling system. Selection of two-speed direct-drive motor, to one machine (ie usually send row when using high-temperature exhaust ventilation and fire), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, high efficiency, small size, easy installation (horizontal, vertical, lifting may be), etc., are widely used in high-rise buildings, drying room, underground garages, subways, tunnels and other occasions to send fire smoke and exhaust ventilation . Press GA211-1999 Fire fan exhaust fan price high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / times without damaging the exhaust fan, has been the country cities approved for use by the fire department. Fans of the series can be installed in accordance with the requirements of occasions, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan fire.
