Our NXT Dual Chemical Extraction Hood provides the highest level of operator and environment protection from harmful chemicals available today. Quality materials, components and workmanship can be found in this fully loaded NXT series hood.


  • Operator Protection
    The airflow is directed away from the operator, into the hood to be filtered. Both the NXT-340 and 440 models have been successfully ASHRAE 110 tested with excellent results.
  • Chemical Filtration
    Contaminated air passes through a carbon filter designed specifically to the chemical to be absorbed in each hood.
  • Independent Operation
    Internal fan(s) direct air without the need for the air to be ducted to the building system. The filtered air is vented back into the room, saving otherwise wasted energy.
