Compact laboratory hood offers many filter options
AirScience
The DWS Downflow Workstations (photo) ensure safety and low noise levels for laboratory operators. They recirculate air (rather than discharging expensive conditioned air to the atmosphere). This reduces HVAC strain and lowers overhead costs, says the company. The DWS Workstations are designed to provide a small bench-mounted unit with unrestricted access for operations that may be hard to perform in a conventional fume hood. A variety of filters can be selected to meet the needs of the laboratory; these include 14 different types of carbon and specialty media for vapors such as organics, solvents, acids, mercury and formaldehyde. HEPA filters for particulate filtration are also available. — AirScience, Fort Myers, Fla.
