FR 140 Centrif. Inline Fan

Item Number: 411333

• The FR series includes 6 fan model sizes with airflow capacities between 150 and 345 cfm
• Vibration welded seam ensures leak proof housing
• 100% speed-controllable
• Air stream temperatures up to 140 °F

Application

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.

Design

The fans feature a fully sealed plastic housing.

The housing 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.

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.

Motor protection

Thermal overload protected with automatic reset. The fans can be controlled via a solid state speed controller.

Description

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.

Guide Specifications for Model FR Inline Duct Fans

Supply, exhaust or return air inline fans shall be of the centrifugal, direct driven type.

Housing

Fan housing shall be constructed of UV resistant, flame retardant Polycarbonate (PC) thermo plastic.

Capacitor shall be provided and shall be located within the fan electrical terminal box for easy access. Electrical terminal box is water tight.

Motor

Motorized impeller shall be an external rotor type, class B insulation, totally enclosed PSC Type for maximum efficiency.

Motor shall be a permanently sealed self lubricating ball bearing type.

Motor shall be equipped with automatic reset thermal overload protection.

Motor shall be acceptable for continuous duty.

Sufficient service factor shall be provided to ensure long maintenance free operation over maximum load conditions.

Wheel

Fan wheel shall be of the backward inclined centrifugal type with a well designed inlet venturi for maximum performance.

Motorized impeller shall be both statically and dynamically balanced as one integral unit to provide for vibration free performance.

Performance

Fan air flow performance shall be certified by HVI and licensed to bear the HVI Tested/Certified Performance Logo.

Code Approval

Fan shall be certified by UL for safety.

FR Series shall be manufactured under the authority of Fantech, Inc., Lenexa, KS.
