Vostermans Multifan Greenhouse HAF Q Fan. 20 240v (4,765 CFM)

Vostermans Multifan HAF Q 20-inch greenhouse circulation fan The Multifan HAF Q 20-inch is a severe-duty horizontal airflow fan that moves up to 4765 CFM through a greenhouse. A unique housing tightens the airflow pattern for long throw and even movement without disrupting plants. An IP55 rating handles dust, water, and wash-down, and the aluminum-enclosed Class F motor dissipates heat to 140F. A lightweight polypropylene impeller cuts motor wear and extends fan life. Severe-duty HAF fan for serial or parallel greenhouse systems Growers run HAF fans in a serial or parallel loop to circulate air the length of a greenhouse. The 240V, 1/2 HP, 1.8-amp motor is variable-speed capable for tuning airflow. Sealed ball bearings front and rear carry an L10 life rating for long runtime. A white housing and compact frame cast less shadow over the crop. Powder-coated steel guards and corrosion-resistant hardware suit wet rooms. A 3-year warranty backs it.
