Velocity Requirements for XP Dust

Minimum Conveying Velocities of common contaminants to prevent dust "laying down" in ducting

Conveying Velocity Requirements

The Class and Div requirements are only half of the picture

 If the right amount of CFM isn't provided, then over time the duct will fill up with dust accumulation and eventually collapse. We take several factors into consideration to calculate how many CFM are required. Elbows and other resistance points are all taken into consideration to ensure effective and timely evacuation of the contaminants. .

Capture Velocity Requirements

An ideal scenario for optimal operation is 3000 to 4000 fpm in the ductwork and a capture velocity of 150 to 300 fpm.
