Air to Cloth Ratio Calculator

This filter velocity calculator is used to find the ratio of volumetric air flow rate.

  

Air-to-Cloth Ratio Formula:

Air-to-cloth ratio is simply the amount of air going through each square foot of filter media each minute.

v = QA

Where,

v - air cloth ratio m/s

Q - volumetric air flow rate in m3/s

A - total cloth area of filter in m2

The air-to-cloth ratio is typically between 1.5 and 3.5 metres per minute, mainly depending on the concentration of dust loading.
