Interstitial Velocity Calculator
Interstitial velocity in dust collectors refers to the minimum air velocity required to prevent particles from settling in the spaces between filter media. This velocity is critical to the efficiency of the dust collector, as if the velocity falls below the interstitial velocity, dust particles will settle and accumulate, reducing the filter’s effectiveness.
The interstitial velocity is affected by factors such as particle size and density, filter media properties and the design and operation of the dust collector. Maintaining the interstitial velocity is important for prolonging the life of the filter media and ensuring the effective capture and removal of particulate matter from the air stream.
Interstitial Velocity is often confused with another important baghouse term, Can Velocity.
