The Downflow Workstation is a stand alone, ductless unit that protects personnel from powders or fumes.

Applications:
• Dusting for latent prints
• Chemical latent print development
• Solvent and chemical preparation
• Histology
• Powder weighing
• Microscopy

Featuring a unique, open design allows for close inspection of samples while still maintaining a high level of operator protection. When active, particles or fumes are drawn downward through the stainless steel work surface and up through a rear plenum chamber to an electrostatically-charged pre-filter. A main filter then removes remaining contaminants. Once the fumes or particulates have been filtered, clean air is returned to the room. No outside ventilation is required.

The durable, powder-coated aluminum frame provides corrosion resistance and the stainless steel work surface is removable for easy cleaning. A pressure switch for indicating when filters need replacement is included as well as an internal fluorescent light, providing ample illumination without producing heat. In conjunction with the open design of the chamber, the unit provides superior visibility and ample room when working with long items such as rifles and shotguns.

Each unit includes one Particulate Pre-Filter. However, a main filter must be purchased with the unit. The main filter should be selected based on how the unit will be used. For applications involving powders or dry particulates, a HEPA filter should be used. If chemicals and solvents will be used, a Hydrocarbon filter must be used. Main filters are interchangeable, however, the particulate pre-filter should be changed whenever switching between a HEPA or Hydrocarbon filters. Particulate Pre-filters should also be changed upon low airflow. Replacement pre-filters are available for purchase in a pack of 10.
