Fanfare HVAC Lite
Fanfare Lite by Silverglance Software enables rapid sizing of low-volume flowrate (up to 2200 cfm / 1 m3/s) HVAC ducts in a wide range of ductwork types and materials. Fanfare Lite can be upgraded to remove flowrate and duct material restrictions. Calculations also include fan gains and fan motor sizes.
Fanfare operates in either metric or imperial units and uses either UK or USA calculation methods.
