FR 225 Centrif. Inline Fan
Item Number: 411337
The FR series includes 9 fan model sizes with airflow capacities between 150 and 650 cfm
Vibration welded seam (sizes FR 100 thru FR 160) ensures leak proof housing
Adhesive caulk joins and seals the housing for sizes FR 200 thru FR 250
Air stream temperatures up to 140 °F
The FR Series is a versatile inline duct fan. These models can be used for multiple point exhaust, residential and commercial applications, crawl space venting or make-up air supply. They are also widely used as booster fans to move air from one room or area to another. These models are not designed for nor should be used in radon applications.
The fans feature a fully sealed plastic housing.
The housing for model sizes FR 100 thru FR 160 is joined via a vibration welding process. The process uses transverse, reciprocating motion at the point of contact between the housing’s inlet and outlet pieces. The friction produces heat that melts the thermoplastic material at the interface. The melted material quickly re-solidifies, resulting in a fused, single-piece housing. The fused seam is inherently air tight, very strong and permanent.
The housing for model sizes FR 200 thru FR 250 is joined and sealed via an adhesive caulk.
An air-tight fan ensures that efficiency is not lost and contaminants are not spilled due to leakage.
The fan can be mounted in outdoor and wet locations. The FR Series features external rotor motors that have proven dependable year after year.
A large electrical wiring enclosure is designed into the fan housing, making electrical installation easier.
Thermal overload protected with automatic reset. The fans can be controlled via a solid state speed controller.

A centrifugal type exhaust/supply fan specifically designed for moderate size ventilation applications. The fan can be mounted in any angle at any point along the duct work and straight-through air flow design allows easy installation. By using accessory FC type mounting clamps fan can easily be removed from duct work for service. Fans are constructed in accordance with standard dimensions for spiral duct eliminating the need for transition pieces. Fan motors are capable of operating in air stream temperatures up to 140 oF. Motor bearings are permanently sealed, self lubricating ball type. All fans are 100% speed controllable through a decrease in the voltage by using a solid state or transformer type control. All FR Series fans are backed by Fantech’s Five Year Warranty.
