The WIBObarrier horizontal works with the proven WIBObarrier air flow. This creates a needs-based containment workstation in which containers can be safely docked, filled or emptied, and then undocked. The integrated vertical and horizontal clean air curtains reliably shield the protected area. The well thought-out design with precisely coordinated air outlets, regulators, and pressures ensure high directional stability so that no particles penetrate from the outside. Clean air flows inside the protected area. Product emissions are safely captured and discharged. The WIBObarrier horizontal ensures safe personal and product protection when working with critical substances up to OEB 3 and achieves clean room class ISO 7 according to ISO 146441-1.
