Scope of application: This series of purification worktable is one of the necessary basic equipment for biological technology research and experiment, which is widely used in medical and health, universities and other industries for air purification in operating areas. Structural features: 1. It is divided into horizontal laminar flow type and vertical laminar flow type. 2. Low energy consumption centrifugal fan is adopted, and reasonable air duct design is adopted to make the air flow more even and stable. 3. The operating table is made of mirror stainless steel, which is corrosion-resistant and easy to clean; 4. Standard primary efficiency and high efficiency filter, so that the filter effect meets the requirements of users' purification level; 5. The control system is integrated with microcomputer and the wind speed can be adjusted; 6. Folding front door design, up and down can be positioned arbitrarily; 7. The stand and cabinet are designed separately for convenient transportation.
