Product introduction: The vertical air purification bench is a kind of local air purification equipment which is widely used in the fields of chemistry, microorganism experiment and so on. Points: 1. Positive pressure filter system with vertical laminar air supply to prevent cross-contamination of samples inside the operation room. 2. Super-efficient non-baffle filter, with the particle filtering efficiency of 0.3 micron reaching 99.99%(the cleanliness of operation area is much higher than 100 grade). 3. Adopt touch controller, adjustable wind fan system, with low noise and low vibration, to ensure the wind speed in the work area is always in an ideal state. 4. The work table is made of 304 stainless steel, beautiful, easy to clean and corrosion-resistant. 5. The surface of the box adopts electrostatic spraying technology, which is resistant to acid and alkali, beautiful and generous. 6. Balance weight, arbitrary lifting front window, flexible positioning and multi-function socket are provided to provide convenience for operators. 7. Separate structure, with universal casters and fixed foot cups, convenient to move and can be fixed.
