Three reasons why linear slot diffusers are the best choice for “washing windows”


  1. It is always better to put the air down in front of the glass, creating and “air curtain” effect, rather than directly onto the glass. Linear slot diffusers will accomplish this the best.
  2. ASHRAE Standard 62.1 states that the Throw to 150FPM should reach 4″-6′” from the floor. Again, easier to accomplish with linear slots.
  3. ASHRAE Standard 55 requires a maximum of 5 degF stratification from ankle region to neck region. This too, is best done with linear slot diffusers.
