Check the listing for details. Vertical Air Flow Mini Desktop Laboratory Laminar Flow Cabinet 2ft. Condition: New. Listed at 1795.00 USD. Working PrincipleFirst, the air is inhaled through the fan and then filtered by the HEPA filter through the static pressure box. After that thefiltered clean air is sent out in the state of vertical or horizontal air flow, so that the operation area continues to reach the100-level cleanliness under the control of clean air and to ensure the production of environmental cleanliness requirements. Application RangeThe vertical flow clean bench is noisy than horizontal clean bench because its fan is installed at the top. The wind blowingvertically so it is often used in medical engineering to ensure the operator’s health.Vertical laminar flow clean bench is widely used in areas requiring partial cleaning, laboratories, biopharmaceuticals,optoelectronics, microelectronics, hard disk manufacturing and other fields. Characteristics 1. Vertical air flow 2. Using remote to control the wind speed (two-stage wind speeds) 3.Equipped with HEPA filter.
