Duct Fitting Loss Calculator -

By accurately sizing fans, you prevent over-pressurizing the system, which wastes energy.

you are calculating (e.g., radius elbow, mitered bend, reducer)? What is your airflow rate (CFM) and duct size ? duct fitting loss calculator

The volume of air (CFM or L/s) passing through the fitting. By accurately sizing fans, you prevent over-pressurizing the

Proper sizing prevents noisy systems and ensures adequate air delivery to rooms. By accurately sizing fans

By calculating both straight duct friction loss and fitting loss, they provide the total static pressure needed for proper duct design. Key Data Used in Calculations

They calculate the pressure loss in inches of water gauge ("wg) or Pascals (Pa) for various round and rectangular fittings.
