The MicroVac Portable Cleanroom Vacuum Cleaner from Terra is a handheld cleaner that is lightweight and completely portable. Flexible attachments provide users the tools needed to clean tight corners and delicate equipment. A four-stage ULPA filtering system removes particles and dust (down to 0.12 µm) from the air before the air is recirculated to the cleanroom. The vacuum is designed for removing chemical powders in biological safety cabinets and other enclosures. Made of stainless steel housing, the vacuum is suitable for most cleanroom uses, including USP <797>-regulated areas. MicroVac also can operate as a clean air source for controlled environments, including glove boxes.
