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 - 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.
