Targets Dead Zones

Directional airflow breaks up stagnant air in corners, behind piers, and distant areas—only crawl space fan that can be positioned to reach problem zones passive vents miss.

Professional 12" Fan

Full-size 12-inch fan delivers 1,115 CFM—far exceeds the 3-5 inch fans in typical systems, providing the air volume needed for effective large-space circulation.

Designed for Modular Entry

Two-piece construction separates for easy entry through tight crawl space access doors, then reassembles in seconds—brings professional power where it won't fit assembled.

Multi-Fan Flexibility

Use multiple units strategically to create cross-ventilation or custom air patterns—portable design allows repositioning to meet specific moisture control needs.

Eliminates Dead Air Zones

This powerful 12-inch portable circulating fan delivers 1,115 CFM on high speed to move stagnant air in crawl spaces, eliminate dead zones, and create cross-ventilation patterns that prevent moisture accumulation. The modular two-piece design separates for easy entry through tight crawl space access, then reassembles to stand 22 inches tall—providing professional-grade air movement that reaches areas passive vents cannot, improving overall air quality and moisture control beneath your home.

Quiet Three-Speed Operation

The variable speed controller (1,115 CFM high, 822 CFM medium, 529 CFM low) operates quietly even at high speeds, making continuous operation practical without noise concerns. The dual bearing spindle construction provides smooth, vibration-free operation and extended motor life—built for the long-term continuous use required in crawl space applications.

Strategic Fan Placement:

Single Fan Applications:

    • Position to push air from intake vent toward distant dead zones
    • Aim at problem areas with persistent moisture or odors
    • Direct airflow from dehumidifier throughout space
    • Create circulation in stagnant areas behind equipment

Multi-Fan Strategies:

    • Cross-Ventilation: Position fans to move air from intake vents to exhaust vents
    • Circulation Loop: Create air movement patterns that reach entire crawl space
    • Zone Targeting: Place fans to address specific problem areas simultaneously
    • Layered Defense: Combine with exhaust system for comprehensive moisture control
