AirClean ® Systems PowdersSafe 710 and 720 models provide an effective and safe weighing environment for low to intermediate toxicity compounds. These Type A enclosures utilize SafeChange technology that eliminates exposure to the operator when replacing the initial pre-filter. The electrostatically charged pre-filter is easily bagged out under negative pressure.  
  
When fitted with AirSafe automatics safety controller airflow and filter condition are constantly monitored. AirSafeT automatic safety controller provides full control of airflow settings allowing fine powders to be handled with out disturbance of sample. Type A enclosures provide balanced negative pressure at the face of the enclosure to minimize operator exposure. They incorporate both pre-filtration and HEPA filtration. Type A enclosures should not be used with high toxicity or unknown compounds.
