Wood Dust and Trim Collection and Extraction
Designing Your Collection System for Woodworking Dust Collection, Trim Extraction Systems, Paper Trim Collection Systems and more.
A dust collection system is an air quality improvement system used in industrial, commercial, and home production shops to improve breathable air quality and safety by removing particulate matter from the air and environment. Dust collection systems work on the basic formula of capture, convey and collect (you can read more about the role of each of these factors over at our, Industrial Dust Collection Systems page)
The world of conveying in industrial dust collection is complex in and of itself. A properly designed system with pipe correctly sized, the correct metal selected and the proper air-flow components goes a long way to creating an effective Collection System for Woodworking Dust Collection. Again, ppr size, metal choice and the proper choice of components are essential. Let’s look at each.
Sizing pipe for a system for woodworking dust collection or paper trim collection systems, for example, depends largely on the Cubic Feet per Minute (CFM) of your system. CFM is usually regulated by the fan speed of the collector as well as the capacity of the fan installed. Systems are often sized with a fan that offers little more than the maximum CFM needed for the collection system. See the chart below for a guide to selecting pipe diameter based on CFM.
Choosing material/metal for a system will depend largely on the material being conveyed through the system. Wood dust collection is mildly abrasive and not typically corrosive, so most often galvanized metal is chosen. However, some trim extraction systems might convey abrasive particulate or corrosive laden material and such system might need a heavier gauge stainless steel product, just as food grade process would require stainless steel.
Component selection usually deals with air flow control. Gates, butterfly valves, blast gates, diverter valves and explosion isolation valves all regulate air flow for varying reasons. The more flexibility a system has to open-close or direct air flow, the more efficient the system is likely to be. A well designed Collection System for Woodworking Dust Collection, Trim Extraction Systems, Paper Trim Collection Systems and almost any application would include gates and valves to regulate air flow and thus maximize the CFM capacity of the fan. In short, you can direct air where you need it, when you need it. Gates and valves can be operated manually by system users or automatically based on electrical signals form operating or shut-off equipment.
