Standard Construction Features Model SQ Direct Drive 5 4 1 2 Model BSQ Belt Drive 5 9 2 4 7 8 6 1 4

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 SQ sizes 6-16 and in BSQ sizes 7-). 2 Drive Frame Constructed from heavy-gauge steel. 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. 6 Bearings 1 percent factory tested bearings are designed specifically for air handling applications with a minimum L 1 life in excess of 1, hours (L 5 average life in excess of 5, hours). 7 8 9 Drive Assembly Drives are sized for a minimum of 15 percent of driven horsepower. Machined cast iron pulleys are factory set to the required 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. Shaft 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. 5

Vari-Green Options 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 - /4 horsepower 115 volt only. 1 horsepower 115/28-2 volt. 2 horsepower 28-2 volt. All motors are available in a 5/6 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 -7% depending on. 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 s. A cooler motor has longer motor life and reduces energy consumption. 8% usable turndown vs. %. (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. 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 adjustment Features 1. Dial on Motor Control - A potentiometer (dial on motor control) is mounted on the motor for easy speed adjustment for system balance. Simply turn the dial; there are no belts and pulleys to adjust. 2. Control Wire Inputs - the motor accepts a -1 VDC signal from Building Automated Systems, Vari-Green Controls or other controls to adjust motor speed.

Vari-Green Options 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.

Vari-Green Controls Transformer - Provides 24V power from the existing line voltage at the fan to the Vari-Green motor and controls. Dual voltage primary (12/24V) transformer provided with the fan. Remote Dial - Allows for remote, manual airflow adjustments. Wall plate with dial may be mounted in a standard 2x4 inch electrical junction box. Two Speed Control with Integral Transformer Control allows motor rpm to be set at two independent speeds (high or low). Meets minimum airflow requirements with the ability to bump up to high speed in an emergency or meet maximum airflow requirements, or reset to low for energy conservation. Constant Pressure Control - Indoor - Control Vari- Green motor via static (variable volume) or velocity (constant CFM) pressure on the inlet or outlet side of the fan. Optional, one or two, duct or room probes for use in: Multifamily structures - Apartments, condos, hotels; dryers, residential kitchens and bathrooms. Institutional facilities - Schools, prisons, multistory office buildings; bathrooms. Constant Pressure Control - Outdoor Control Vari-Green motor via static pressure on the inlet side of the fan. Includes one duct probe and transducer for use in: Multifamily structures - Apartments, condos, hotels; residential kitchen, dryer facilities and bathrooms.

Filter Options The filter box is designed to provide a compact and convenient clean air solution. Factory-assembled as a single unit, this fan eliminates the costly process of designing, fabricating and installing special remote filter box assemblies. Both the fan and filter section feature removable access panels on both sides to remove and replace filters, making fan maintenance simple and fast. Model Selection Procedure 1. Calculate system pressure drop and cfm requirements (not including filters). 2. Make a preliminary model size selection.. Calculate a filter pressure drop (P) for the preliminary cfm model size selected in step 2 using the equation: P = F x ( 1, ) 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.

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 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 performance will change with different discharge positions. Catalog data is based on an inline discharge. Right side discharge will give you 18% of cataloged performance and left side will give you 19% of cataloged performance. Use figure 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.

Typical Installation 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.
