Dust Collection Information
To aid in the response to questions from the Dust Collection and Air Filtration discussion group, we've created this informational section.
Since creating the Dust Collection and Air Filtration discussion group, we've noticed some of the questions tend to be somewhat similar in nature. To aid in the response to these questions, we've created this informational section. We'll continue to add relevant information to frequently asked questions, so stop back from time to time to review.
The System is the DC system itself. It consists of the hood, the ductwork, the collector (usually a cyclone for our purposes), the fan, and the after filters if used. Each of these components works together to collect the dust at it's source, transport it to a desired location, and separate it from the air, and recycle or exhaust the cleaned air.
CFM is a volumetric measurement of air flow - Cubic feet per Minute.
Static Pressure is an expression of the resistance of the system. It's a sum of all the entry, acceleration, friction, collector, and filter losses. It's expressed in inches of water column.
Velocity is the speed at which the air is traveling through the ducts. It is calculated by dividing the airflow in CFM by the cross sectional duct area in square feet.
|This discussion group and FAQ section are intended for hobby/home woodworking dust-collection systems. Anyone with a commercial shop, who is subject to governmental regulations, or who has allergies or another needs for an industrial system should hire a professional engineer to design, specify, and certify the performance of an industrial dust-collection system.|
