A high-performance, laminar flow local exhaust device utilizing the principles of a tornado has been completed in Sweden.
Regarding the draft chamber and the BT-type exhaust hood utilizing artificial tornadoes, in the current laboratory setting, local exhaust devices such as draft chamber hoods are common. However, for the first time in the world, a high-performance, laminar flow local exhaust device, the BT series, has been completed in Sweden, applying the principles of tornadoes. Tornadoes occur over the sea or in vast plains, and they are phenomena where the suction power of the central core draws in surrounding air. This suction phenomenon is artificially generated within the hood, creating a device called the Tornado Hood, which ensures a uniform intake airflow speed (laminar flow exhaust) at the front opening of the hood. Because the intake at the front of the hood is laminar (with uniform speed), turbulence and vortices do not occur, ensuring the safety of the experimental operators.

basic information
【Features】 ○ The BT series, a high-performance local exhaust device utilizing the principle of a tornado, has been completed in Sweden. ○ The device artificially generates a suction phenomenon inside the hood, creating a uniform (laminar flow) airflow at the front of the hood. ○ Since the suction at the front of the hood opening is laminar (uniform speed), turbulence and vortices do not occur, ensuring the safety of experimental operators. ○ The tornado generated from the central core effectively sucks in air, making it ideal for exhausting gases heavier than air, such as formaldehyde. ○ By enclosing the source of harmful substances and exhausting them, the device is less affected by turbulence outside, effectively capturing and discharging gases, dust, odors, and heat. ○ Built-in exhaust fan type (only type I) → Easy to install and space-saving due to the built-in exhaust fan. → Reduces unnecessary exhaust by adjusting the exhaust airflow as needed. → The built-in exhaust fan capacity controls airflow speed at 0.4 m/s. ○ External exhaust fan type (separate from the Renaud hood) → No worries if you need a high exhaust airflow, have a long distance to the exhaust outlet, or want to consolidate multiple units into one system. → Select a high-performance exhaust fan suitable for the situation. ● For more details, please contact us or refer to the catalog.
