Indoor air quality

The New DWS range of Downflow Workstations from Air Science give the operator safety where routine work is being carried out, the company says. These units operate at low noise levels and because they re-circulate, they do not exhaust expensive conditioned and/or heated air into the atmosphere. DWS Workstations have been specifically designed to provide a small bench mounted unit with unrestricted access for those operations that are difficult to perform in a conventional fume hood. The downflow action takes the contaminated air away from the operator and an alarm will sound when the airflow falls to an unacceptable level, the company says. The main filter can be chosen from 14 different types of carbon, and HEPA filters for particulate filtration are also available to suit the application.
