FG 8 EC Centrif. Inline Fan

8" inline duct fan w/metal housing, EC motor, 120V, 1~

Item Number: 49901

• High level of efficiency

• Integrated motor protection

• Pre-wired speed control potentiometer for air flow adjustments and balancing

• BMS compatible

Application

The FG EC Series is designed for installation in ducts.These fans are known for their economical use of energy and ease of control. They can be varied in speed to match an application's demand, and operate at high efficiency levels. For the same air volume, they consume considerably less energy than an AC fan.

Design

The casing is manufactured from galvanized sheet metal with the seams folded to give the fan an air tight casing. All fans have a minimum 1" long connection collar. The fans have backward-curved blades and external rotor EC-motors.

Speed control

The FG EC fan motor's speed is controlled via a 0-10Vdc signal. The motor provides a +10V reference that can be used by a remotely-mounted potentiometer (such as MTP 10). The motor can also be controlled by an externally-provided 0-10Vdc signal that can come from any device or a Building Management System (BMS). The fan's motor also provides operational speed (tachometer pulse) output that can be used to verify fan operation. These control features allow the FG EC to be integrated into and play an active role in smart HVAC systems in buildings.

Motor protection

Motor protection is integrated in the electronics of the motor.

Description

A centrifugal type exhaust/supply fan specifically designed for moderate size entilation applications. The fan can be mounted at any angle in any point along the duct work and straight-through air flow design allows easy installation. By using FC type mounting clamps, fan can be easily 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 140o F. Motor bearings are a permanently sealed, self lubricating ball type. All fans are 100% speed controllable through a decrease in the voltage by using 0..10V potentiometer. All FG EC Series fans are backed by Fantech’s Five Year Warranty.
