    Diff in Grill or Slots

    Grill type diffusers our the standard type diffusers where you have more control. Theres are the ones you typically see at offices, in ceiling grids, etc.

    Slot diffusers are typically used in nice hotels, restaurants, executive offices, where they want to conceal the air outlets/ inlets. They can be used for return air, supply or exhaust. Slots can also be strung together one next to the other to have a continuous long diffuser. They are typically installed close to the and along walls where there is low visibility.

    Also, Slots are just openings with no louvered face. Typically you can get them in single slot where there is only one opening or even up to 2, 3, or 4 slots. Typically they can be only purchased as one way throw or bi directional.

    Hope that helps!? You can get these from Price or Titus.

    throw

    You had it right the first time, it’s all about throw and the throw you choose will depend on the building design shape and interior layout as our good friend has mentioned. You pick the style that best distributes the heating or cooling for a given load.

    Slots, or liniers(sp?), will be used for perimeter or soffit applications MOST of the time. You do see them in offices quite often and they make them to fit over lights as well (light troffers), usually used as a return. Most of the time you'll see both slot and lay ins used in the same space. Personally I would only recommend them for only perimeter and soffit use.
