Portable Fans can be used in your crawl space for cross ventilation, directing air to dead spaces or move air in larger crawl spaces to your dehumidifier.
Portable Fan separates into two pieces for easier install. Position fan in direction you want air to flow or towards dead spaces. Dead spaces in your crawlspaces are nooks and corners that do no get good air flow.
Always plug crawl space fans into proper GFI outlets. We do not condone running extension cords in your crawlspace.
