16-20 inch Stainless Ceiling Air Circulation Fan for Greenhouses

Greenhouse air stratifies badly — hot air collects at the ridge while crops at bench height sit in cold, humid, still air that invites fungal disease. A ceiling-mounted air circulation fan breaks that layering up without adding heat or drawing in outside air. Stainless steel throughout survives the fertiliser mist and constant humidity that destroy painted steel within a season. 16 or 20 inch at 1400rpm, voltage customisable.
