AirSafe™ TOUCH Automatic Safety Controller
All operational features can be accessed from the two MAIN CONTROLS screens.
Independence™ ductless fume hood incorporates the first color touch screen controller on a laboratory fume hood. Independence™ AirSafe™ TOUCH allows approved operators to set, monitor and control all operational and safety features.
The MAIN CONTROL screen has three primary informational areas for Independence™ system information and control.
Informational Area 1 provides blower condition, gas fixture status, electrical outlet status and current logged in user by visual indication of written text. During alarms, this area changes color from blue to red.
Informational Area 2 displays the quick keys, face velocity in either LFM or M/s and gas detection level in PPM. The quick keys allow the approved operator to move easily between approved modes within Independence™.
Informational Area 3 displays the mode/screen that Independence™ is currently in, the time and date, and a home key that will quickly return the user to the main control screen.
