Here we bring to you the Fantech FR 100 Inline centrifugal duct fan, 122 CFM, 4 Inch Review, a user-friendly, residential, and commercial inline centrifugal duct fan for multiple-point exhaust, better performance, and increased versatility.
What Is a Fantech FR-100 Inline Centrifugal Fan?

This is a versatile FR Series inline centrifugal duct fan. It can be used for multiple-point exhaustion. And it comes in handy for both residential and commercial applications. A user can also utilize this duct fan for crawl space venting or to make up the air supply. Such a duct product is widely used as a booster fan to move the atmospheric air from one room (or area) to another.
This inline mitigation fan features a fully sealed plastic housing, secured via vibration welding. It uses a transverse and reciprocating motion at the point of contact between the inlet & outlet pieces. The thermoplastic substance present at the interface melts due to friction-producing heat. This softened material quickly resolidifies, resulting in a particular & fused piece housing. This is essentially strong, airtight, and permanent. And no screw or adhesive is employed to stick together the housing pieces.
How Does the Fantech FR 100 Inline Centrifugal Duct Fan, 122 CFM Work?
This centrifugal exhaust fan is designed specifically for moderate-sized ventilation applications. It can be mounted at any angle and at any point along with the duct. And hence, this straight-through airflow plan enables easy installation.
Using the FC-type mounting clamp, this fan can be easily separated from the duct for service. It’s basically constructed in accordance with the standard dimensions for a spiral duct elimination,n leading toward the need for transition pieces.
