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..

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..
