Triangle Fans Whole House Fans help cool your home by bringing in fresh outdoor air and pushing out hot, stale indoor air through the attic. These fans are a cost-effective way to improve air quality and reduce the need for air conditioning. They are perfect for home use, especially during warmer months. Each fan is built with a strong steel housing and runs on a dependable two-speed motor. You can easily switch speeds using the pull chain, depending on how much airflow you need. Rubber mounts help reduce noise and vibration, making the fan quiet enough to use at night. The fan also comes with a no-cut CSS shutter that fits between ceiling joists, so no extra construction is needed during installation. It’s simple to set up and works with optional accessories like a 12-hour timer (sold separately) for added convenience.
Triangle's CSS shutters are constructed with heavy-duty extruded aluminum frames. Not only do these shutters provide effective airflow but they also operate quietly. The shutter function automatically opens, allowing air movement, and closes when the fan is off.
