Trimline Hoods and Ventilators
Model TEV - For exhaust or gravity relief. Includes 1 to 1 ratio of hood perimeter opening to throat area. Maximum Design velocity of 1200 fpm.
Model TIV - For fresh air intake. Features a 2 to 1 ratio of hood perimeter opening to throat area. Design velocity at perimeter of 600 fpm to minimize moisture entertainment.

  • Low Silhouette design
  • Full 360o perimeter hood opening for more reliable air flow performance
  • Generously sized throat and hood perimeter for low resistance and more efficient air flow
Construction & Features
  • Base Constructed of .080" aluminum

Ptotective Coatings
  • Epoxy - a tough gray coating that is one of the best heavy duty multipurpose finishes resistant to most chemicals and corrosives
  • Eisenheiss - a synthetic resin that forms a tough coating offering better protection against most acids and corrosive agents
  • Heresite - a black phenolic coating that has good resistance to heat, solvents and concentrates of most acids except strong oxidizing agents (resistant to weak alkalis but not recommended for hydrofluoric acid or hypoclorite salts)
