The Santa Fe Impact155 was specifically designed for large basements and crawl spaces. The high-capacity (391 cfm) blower on the unit circulates air more effectively in larger applications. The Santa Fe Impact155's horizontal configuration, dual outlet design, and insulated cabinet for quieter operation enable its exceptional performance in all larger basement and crawl space applications. Levelling feet come standard on the Santa Fe Impact155 to help ensure proper operation. Optional condensate pump and ducting kits provide the installation flexibility necessary for the most challenging applications.
