Standard Construction Features

1 Cabinet Construction

The fan housing is constructed of rigid structural members and formed galvanized steel panels. (Aluminum construction is optional in all SQ sizes 60-160 and in BSQ sizes 70-300.)

2 Drive Frame

Constructed from heavy gauge steel.

3 Wheel

An aluminum, backward inclined, nonoverloading centrifugal wheel is utilized to deliver maximum efﬁciency. Each wheel is statically and dynamically balanced.

4 Duct Collars

Inlet and discharge duct collars are provided for easy duct connection. The square design provides a larger discharge area than tubular centrifugal, and vane axial fans; outlet velocities are reduced for quieter operation.

5 Motor

Permanently lubricated, sealed ball bearing motors are selected to provide years of trouble-free operation with minimal maintenance.

7 Drive Assembly

Drives are sized for a minimum of 150 percent of driven horsepower. Machined cast iron pulleys are factory set to the required RPM and adjustable for ﬁnal system balancing. Belts are static free and oil resistant. Belt adjustment is accomplished by loosening fasteners, sliding the motor plate and retightening fasteners.

8 Fan Shaft

Precisely sized, ground and polished so the ﬁrst critical speed is at least 25 percent over the maximum operating speed. Close tolerances where the shaft makes contact with bearings result in longer bearing life.

9 Disconnect Switch

NEMA-1 disconnect switch is factory mounted and wiring is provided from the motor as standard. All wiring and electrical components comply with the National Electric Codes and materials are UL Listed. Other NEMA enclosure disconnect switches are optional.

Access Panels (not shown on images)

The cabinet construction features two side access panels. These panels permit easy access to all internal components.

6 Bearings

100 percent factory tested bearings are designed speciﬁcally for air handling applications with a minimum L10 life in excess of 100,000 hours (L50 average life in excess of 500,000 hours).

The Greenheck VariGreen (VG) motor blends

Reliability

With industry leading technology comes a new standard in motor reliability

• No shaft grounding required regardless of the turndown

• Bearing life is greater since the motor runs cooler the further it is turned down

• No voltage or current spikes as in VFD controlled motors

Electronic Commutation

Electronic commutation uses electronic circuitry to control the motor’s functions:

• Solid state circuitry controls the output of power and the speed of rotation

• Internal circuitry converts 115 volt single phase AC power to DC voltage for increased efficiencies and full controllability of speed

Speed Control Options

Motor is available with one of these control options:

1. Motor mounted dial

2. Control wire inputs (0-10V)

3. Remote dial (available with 0-10V motor).

Motor and Fan Sizes

VG Motors come in three fractional horsepowers; 1/4, 1/2, 3/4 and are available in both 50 and 60 Hz power on models G, CUE, CW, and SQ. Consult factory for other motor sizes available.

Specifications

• Motor enclosures: Open type

• Motor to be a DC electronic commutation type motor (ECM) specifically designed for fan applications. AC induction type motors are not acceptable. Examples of unacceptable motors are: Shaded Pole, Permanent Split Capacitor (PSC), Split Phase, Capacitor Start and 3 phase induction type motors.

• Motors are permanently lubricated, heavy duty ball bearing type to match with the fan load and pre-wired to the specific voltage and phase

• Internal motor circuitry to convert AC power supplied to the fan to DC power to operate the motor.

• Motor shall be speed controllable down to 20% of full speed (80% turndown). Speed shall be controlled by either a potentiometer dial mounted at the motor or by a 0-10 VDC signal

• Motor shall be a minimum of 85% efficient at all speeds

Discharge Configurations

The side discharge option helps to reduce system effect. It will increase performance and reduce installation labor. The most notable is reducing system effects. Note the figure 1 example, it shows the air being discharged into the corner. It will take several duct lengths before the airflow becomes laminar or smooth again after making the turn. In figure 2, the fan is placed in the corner using a side discharge. In this configuration the air flow pattern at discharge is smooth and supports a more predictable system. Remember the duct length on the discharge side, should be approximately two to three wheel diameters to achieve catalog performance.

Left Discharge

Discharge Configuration

Fan performance will change with different discharge positions. Catalog data is based on an inline discharge. Right side discharge will give you 108% of cataloged performance and left side will give you 109% of cataloged performance. Use figure 3 to locate the orientation to fit your application. Figures 4 and 5 on the facing page illustrate the proper side discharge definitions. Refer to the CAPS program or consult factory for performance modifications.

Typical Installation

Models SQ/BSQ ducted inline fans are designed for the exhaust, supply or recirculation of air in a building. Typical installation requires ductwork on the inlet and outlet side of the fan. A minimum of three duct diameters is required on the inlet and outlet of the fan to minimize system effect losses. See the diagram below for a typical installation.

Installations can include flexible duct connections (by others) on either the inlet or outlet side of the fan

or both. The motor is rigidly mounted and can be oriented in any direction (top, bottom, side).

The model BSQ ducted inline fan must be installed with the motor accessible for maintenance and inspection.

External isolators are recommended, hanging (shown below) or base mounted.

Installation must meet all local governing codes and the NEC.
