    Due to the offset design this should give a cleaner airflow when fitted in certain situations. This is why I purchased this unit.

    Great Reducer

    M.S. · 4 February 2021

    I needed it to connect the 4 inch exhaust tube from my laser cutter/engraver to a 6 inch exhaust port on a portable air-conditioning window filler. It's only temporarily in the window, while using the laser cutter/engraver to vent the noxious fumes. Couldn't be happier, it worked flawlessly, I'm cutting and engraving and not smelling a thing, great purchase!
