Air Science‘s new DWS range of Downflow Workstations gives operators safety where routine work is being carried out. Units operate at low noise levels and recirculate air, rather than exhaust expensive conditioned air into the outside environment. This reduces HVAC strain and lowers overhead costs. The DWS Workstations are designed to provide a small bench mounted unit with unrestricted access for operations that are difficult to perform in a conventional fume hood. To provide protection, the downflow action takes the contaminated air away from the operator. If airflow falls to an unacceptable level an alarm will sound. The main filter can be chosen from 14 different types of carbon. HEPA filters for particulate filtration are also available.
