  • Filters are stackable: two identical filters can be stacked for better purification or two filter types can be combined for mixed chemical applications
  • Six types of carbon filter are available for neutralizing mineral acids, sulfur compounds, ammonia, amines, formaldehyde or iodine radioisotopes
  • Optional HEPA filters control airborne particles from powders and similar materials
  • Aerodynamic foils around the sash opening help to smooth out the air inflow for better containment and safer operation
  • Rear baffle features perforated “zones” that create three horizontal, laminar air streams to reduce turbulence
  • Ductless exhaust offers greater flexibility regarding placement within the lab
  • No “make-up air” requirements typically associated with external exhaust systems
  • ECM blower motor provides quiet, energy-efficient performance
  • Built-in filter-life timer reminds personnel to check/change the filters
  • Safety-First™ Organic Vapor Sensor detects contaminants that emerge downstream of the filters
  • Smart-Flow™ Airflow Monitor displays face velocity on the LCD screen and automatically adjusts to changing environmental conditions to maintain safe airflow

Features and Benefits

Ductless Exhaust Airflow Diagram

The blower pulls air into the Paramount ductless enclosure through the sash opening, along which curved airfoils eliminate “rolling” and ensure uniform airflow to the rear baffle. Air travels up and passes through the filters before returning to the surroundings.

Smart-Flow™ Airflow Monitor

The LCD display shows the equipped filter types, the status of the filters, and airflow face velocity. On/off buttons are provided to toggle the blower and light fixture. All settings are programmable and can be electronically locked for security.
