la series fume hoodOur LA-series hood offers added flexibility over our modular BV-series by allowing for custom dimensions and design features such as side viewing windows and pass-through ports. The full bias of the side posts enhances air smoothness at the sash perimeter with minimal reduction in working width (1/2”) over the BV. In the Iroquois tradition of performance, durability and value, the LA comes with a long list of standard equipment.

  • Two hood heights in stock – 48” with 42” interior height; 58” with 48” interior height
  • Welded superstructure for structural rigidity and design flexibility to accommodate custom hood sizes and features
