Automatic Louvers

Shutters open during operation and close when off—prevents backdraft, cold air intrusion, and outdoor air infiltration when ventilation isn't needed.

OSHA Compliant

Meets OSHA Standards Class F with safety guard behind louver—thermally protected motor ensures safe continuous duty operation in confined crawl spaces.

Three-Speed Control

Variable 550/850/1,115 CFM output matches ventilation to conditions—low for continuous use, medium for routine control, high for maximum moisture removal.

Permanent Installation

Wall-mount design with plug-in operation provides set-and-forget exhaust ventilation—no repositioning, no setup, just reliable continuous moisture control.

Permanent Exhaust Solution

This OSHA-compliant 12-inch shutter fan delivers professional-grade exhaust ventilation with 1,115 CFM on high speed, featuring automatic closing louvers that prevent backdraft when the fan isn't operating. The permanent wall-mount design with three-speed control (550/850/1,115 CFM) provides continuous duty ventilation for crawl spaces and enclosed areas, exhausting moisture, radon, and odors through a compact 12" × 12" installation that fits standard foundation openings.

Compact 12" × 12" Footprint

The small footprint fits into tight foundation wall spaces where larger exhaust systems won't work. The 1.75 square foot recommended inlet size means you need minimal makeup air opening to support the exhaust—typically achieved with one or two standard foundation vents on the opposite wall for cross-ventilation.
