Our double bank filter rack are offered in the same models. Exhaust only canopy, Exhaust only canopy with one or two ceiling mounted plenum boxes, Front face discharge make-up air, and internal make-up air. These models are typically seen as Island style canopies in the middle of an open area. All of these models come with choice of UL rated LED or Fluorescent lighting. These styles are popular as island hoods over large cooking line ups due to them having two fronts, instead of a front and a rear. This allows you to double your capture are in an open space and also give the cooking area an extra bit of eye appeal, no matter which side of the hood you are on.
