When designing and intergrading dust collectors in dust collection systems there is an important factor that requires careful consideration, the Air-to-Cloth Ratio. This ratio can determine the efficiency of a dust collector<\/a>. As when this ratio is out of balance or calculated wrong it can create issues or reduce the lifetime of the filter media. <\/p>\n\n\n\n

Air-to-Cloth formula<\/h2>\n\n\n\n

The air-to-cloth ratio is the volumetric flow rate of air (m3\/minute; SI m3\/second) flowing through a dust collector’s inlet duct divided by the total cloth area (m2) in the filters. The result is expressed in units of velocity. Basically, meaning how much air passes through each filter per square meter. This gives the following formula which can be broken down in 3 steps: <\/p>\n\n\n

  1. Determine the total airflow rate in cubic meters per minute (m3\/min). <\/li>\n\n\n\n
  2. Determine the total filter area in square meters (m2). <\/li>\n\n\n\n
  3. Divide the airflow rate by the filter area to get the air-to-cloth ratio in meters per minute (m\/min). <\/li>\n<\/ol>\n\n\n\n

    For example, if a dust collector has an airflow rate of 100 m3\/min and a filter area of 50 m2, the air-to-cloth ratio would be 2 m\/min. <\/p>\n\n\n\n

    What Happens When the Air-to-Cloth Ratio is too Low? <\/h2>\n\n\n\n

    When the air-to-cloth ratio is too low, it typically means that there is more filter media for the amount of air and dust that enters the dust collector. In general the higher the ratio the better With an Air-to-Cloth ratio that’s too low you might encounter issues like: <\/p>\n\n\n\n
