Restaurant exhaust hoods are important for any commercial restaurant kitchen. The Exhaust hood acts as a vent to the smells that come from daily cooking from an oven or griddle. When purchasing a commercial restaurant hood be sure to know the type of hood you need. Different variations include: Make-Up Air, Ventless, and Short-End Hoods. Also know the size that will best suit your restaurant establishment. Exhaust hoods should be constructed from Stainless Steel for longevity and durability.
