Fantech FR100 Inline Centrifugal duct Fan Review

Fantech FR100 Inline Centrifugal duct Fan Molded Housing , 122 CFM , 4″ Review


This is a versatile FR Series inline centrifugal duct fan. It can be used for multiple point exhaustion. And it comes handy for residential as well as commercial applications. A user can also utilise this duct fan for crawl space venting or to even 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 which is fixed through a vibration welding process. 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 the friction producing heat. This softened material quickly re-solidifies and results into a particular & fused piece housing. This is essentially strong, air tight, and permanent. And no screw or adhesive is employed to stick together the housing pieces.


This centrifugal type exhaust fan is designed specifically for a moderate size ventilation. It can be mounted in any angle and at any point along with the duct. And hence this straight through air flow plan enables easy installation.

By making use of 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 leading towards the need for transition pieces.


  • FR 100 centrifugal duct fan performs flawlessly, has strong air suction along with zero vibration.
  • There’s a supplied and prewired mounting bracket for easy installation of the product.
  • It has 9 sizes with the airflow capacities between 150 and 650 CFM.
  • The fan is suitable for air stream temperatures of up to 140°F.
  • The FR 100 centrifugal fan is 100% speed controllable.
  • The motor bearings are sealed permanently.
  • The CFM or the Air Flow Capacity is 122.
  • And it holds a Fantech Five Year Warranty.



  • The speeds are controlled through a decrease in the voltage utilising a transformer type control.
  • Such fans are also widely used as booster fans to move air from one room to another.
  • It makes sure that the contaminants are not spilled due to any sort of leakage.
  • The fan goes completely unnoticeable when it comes to noise.
  • Its vibration welded seam guarantees leak proof housing.
  • FR 100 effectively gets rid of the moisture from the room.
  • Such an air-tight fan ensures that the efficiency isn’t lost.
  • The product is UL listed and is also CSA certified.
  • There develops no mold or mildew.


In some cases the dimension of this product has been misleading. A few users felt that the fan does not fit in any standard 4 inch schedule 40/ 80 PVC. But maximum users are satisfied with the same. So I advise you to make the choice accordingly.
