Typical Installation
Model 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 prevent 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 rigid 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.
