Unit Overview:
In dilute phase vacuum systems,negative air pressure is used to convey materials by suspending themin the conveying airstream. Materialsare conveyed at a velocity above the saltation, or minimum suspension velocity.For materials to reach dilute phase, conveying air velocities of 3,200 to 7,000feet per minute are required. Because these systems convey materials at highervelocities, they’re typically used to convey materials that are not susceptibleto degradation or not abrasive in nature. The type of material being conveyed,how far the material is being conveyed, and/or the properties of the materialwill determine which application is right for you.
