NuAire's PharmaGard ES (Energy Saver) compounding aseptic (CAI) and containment (CACI) isolators produce ISO Class-5 clean air, which meets the USP Standard <797> requirements for compounding sterile products. The in-work-zone sharps and waste system on PharmaGard allows containers to be changed independently. Located under the work zone, the containers have a locking mechanism that creates an airtight seal, maintaining a true ISO Class-5 environment. The improved vertical, sliding, counter-balance, interchange window produces a seamless transition when transporting compounding materials into the work zone.
