Suitable for hospital and laboratory application purpose, horizontal laminar flow hood serves as a filtered air delivery system that delivers air in the same direction without changing its operating speed. Notable for its enclosed structure, it is effective in total removal of contaminated particles at high speed. Sweeping mechanism of this horizontal laminar flow hood conforms to ISO specified cleanliness standard. There are several advantages of this laminar flow hood. It creates minimal turbulence on work surface for its parallel air flow direction. Moreover, the controlled environment created by this laminar air flow unit minimizes the risk of contamination caused by hands or gloves.
