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, non-

overloading 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.

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).

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.

Fan Shaft

Fan shafts are 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.

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

removable access panels permitting easy

access to all interior components.

Vari-Green® Motor - Model SQ

Greenheck’s

electronically

commutated (EC)

Vari-Green (VG) motor

combines motor

technology, controllability

and energy-efficiency into

one single low maintenance

unit and is the industry’s first

fully controllable motor. When combined with

Greenheck’s SQ fans, all the CFM and static pressure

ranges of a belt drive can be attained with the

benefits of a direct drive.

The Vari-Green motor is available in:

• 1/6 - 3/4 horsepower 115 volt only.

• 1 horsepower 115/208-230 volt.

• 2 horsepower 208-230 volt.

All motors are available in a 50/60 Hz power.

Benefits

Operates on AC power that’s converted to DC—

providing a more efficient motor operation as

compared to an AC operation.

• The motor can attain up to 85% efficiency and

reduce energy consumption.

• Watt savings of 30-70% depending on RPM.

Note: As motor speed is turned down, efficiency stays

high as compared to an AC motor that decreases

dramatically.

• Operates cooler than a standard AC motor at lower

RPMs. A cooler motor has longer motor life and

reduces energy consumption.

• 80% usable RPM turndown vs. 30%. (chart at right)

• SQ fans with Vari-Green motors can provide all

the CFM and static pressure ranges of a

comparable belt drive.

• Maintenance costs are reduced as there are

no belts or bearings to replace and no pulleys

to adjust.

• Direct drive fans are often preferred where

maintenance access is difficult.

• The Vari-Green provides a solution for demand

controlled ventilation applications.

Vari-Green Advantages

• Initial cost is similar to a belt drive

• Lower operating cost

• No maintenance, no belts, pulleys or bearings

• Easy RPM adjustment

Demand controlled ventilation offers significant energy savings by

exhausting only the necessary amount of air throughout the day.

Demand Control Ventilation for

Multistory Buildings

Applications requiring constant pressure or variable

volume can utilize SQ fans with Vari-Green motors

and Vari-Green controls.

Demand control

ventilation systems

reduce the amount

of energy used by

decreasing the speed of

the fan when demand

is low. This in turn

lessens the amount

of conditioned air

exhausted and further

reduces total operating

costs associated with

air conditioning and

heating in multistoried

buildings such as: hotels,

multifamily complexes,

institutional facilities,

and high rise commercial

buildings.

Model Selection Procedure

1. Calculate system pressure drop and cfm requirements

(not including filters).

2. Make a preliminary model size selection.

3. Calculate a filter pressure drop (P) for the preliminary

model size selected in step 2 using the equation: P = F x ( 10,000 )2

•To determine the filter factor (F) refer to chart below.

4. Add the filter pressure drop (P) to the system pressure drop and make a revised model size selection.

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 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.

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 page 11 illustrate the proper side discharge

definitions. Refer to Greenheck’s CAPS (Computer

Aided Product Selection) program or consult factory

for performance modifications.

Models SQ and 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.

Model Number Code

The model number system is designed to completely identify the fan. The correct code letters must be specified

to designate belt or direct drive. The remainder of the model number is determined by the size and performance

selected from the following pages.

Performance certified is for installation type B: Free inlet, Ducted outlet. Performance ratings do not include the effects of appurtenances (accessories).

The sound ratings shown are loudness values in fan sones at 1.5 m (5 feet) in a hemispherical free field calculated per AMCA International Standard 301. Values shown are

for installation type B: free inlet hemispherical sone levels.
