Simple to setup, using this for an outdoor building (8' diameter) to minimize dew issues in early morning. Building with a roll off roof has major dew issues in early morning. Was able to set this up quickly, vent to exterior of building pulling air from just below roof line pointed down. Significantly reduced dew on hardware in building by setting up venting due to humidity. As bonus helps to balance temp in building between sundown and full dark so everything inside is the same temp as outside.
