BSI/DSI Square Inline Centrifugal Usage Guide
Refer to the Twin City Fan Revit Family Usage Guide for details on how to load a family into a project. Once loaded the default discharge option is ‘1’ which corresponds to rear discharge. The user can change the discharge option to any one of 7 available configurations by changing the numeric value in the discharge option field. Table 1 describes each configuration. Note that Revit recognizes all duct connections on the fan regardless of the discharge option selected. For example, a rear discharge will have Left and Right duct connections in the model despite the fact that they have no mounting collars and are not valid mounting options. It is important to ensure the correct discharge option is selected and that the duct work, transitions, etc. are in the correct mounting locations. Also, CFM values must be entered for all three discharges. Non-applicable discharges are set to ‘0 CFM’.
Although there are only 7 discharge options available, Revit will allow the user to enter numeric values larger than 7 in this field. Any value greater than 7 will result in an invalid discharge.
How It Works
Twin City Fan’s square inline centrifugal models BSI and DSI have a unique discharge option parameter within Revit. This field allows the user to select the appropriate discharge for the application.
