Durable Construction & Smart Design

The Fantech FR Inline Duct Fan Series is built with long-lasting quality in mind. Each unit features a durable housing made from a UV-protected thermoplastic resin (ABS-PC blend) that stands up to heat, moisture, and everyday wear. The housing is vibration-welded to form an airtight and leak-free seal, keeping airflow efficient and preventing moisture from getting inside. Inside, the fan’s external rotor motor is engineered for reliability and low maintenance. It uses permanently sealed, self-lubricating ball bearings that deliver years of smooth, quiet performance without the need for regular servicing. The FR fan is also designed to handle air stream temperatures up to 140°F (60°C), making it a great choice for both warm exhaust and supply air applications. Its strong resin shell, sealed motor design, and efficient airflow system make it a dependable solution for residential and light commercial ventilation systems where durability, low noise, and easy upkeep are essential.

Customer Questions
Is the FR fan safe to use outdoors or in damp areas?
Yes, the FR fan can be installed outdoors or in damp locations as long as it’s protected from direct rain or water exposure. The motor is enclosed for added protection against moisture (IP44 rated), making it safe for semi-outdoor use.
Can I adjust the speed of the FR fan?
Yes, you can. All FR models work with compatible fan speed controllers, so you can fine-tune the airflow to match your ventilation needs.
How often should I clean or check the FR fan?
For normal home or light commercial use, it’s a good idea to inspect and clean the fan every six months. If you’re using it in a dusty or humid area, check it more often, around every three months.
Is the FR fan noisy when running?
Not really. The FR fan is designed to run quietly, and most of the noise you might hear usually comes from air moving through the ducts.
What is the minimum CFM this fan can operate at, and can it run 24/7 in a crawl space?
The FR-100 fan is rated up to 151 CFM and is designed for continuous 24/7 operation, making it suitable for crawl space ventilation. The minimum required CFM depends on the crawl space size, but this fan provides sufficient airflow for most small to medium crawl spaces when properly installed.
