Accessories
The Accessories form enables the user to specify which accessories to include with the fan.
Different losses are associated with each accessory.
Refer to the 'Options - Configuration' menu to adjust K factors for each of the accessories.
(Pressure loss is equal to Velocity pressure times K factor).
Note that Centrix will calculate the losses and subtract them from the fan performance figures. Fan pressures and efficiencies are reduced when accessories are chosen. Loss factors can be set in the 'Options - Configuration' menu.
Select any accessories required and click the 'New Selection' button.
