Your dust collector can be sized correctly. Your fan can be powerful enough. Your ductwork can be designed properly. But if the hood isn't capturing dust at the source, the whole system has to work harder. Effective dust collection starts where the dust starts. Learn how hood design, capture velocity, CFM, static pressure, and transport velocity work together to keep contaminants out of your facility's air.
Stitched Elbows
Stitch-welded elbows, or stitched halves, are galvanized metal elbows that are stamped out using mechanical presses and forming dies, resulting in a very tight elbow.
The stamping process does limit the gauge & diameter (up to 22 gauge and 1xD or 1.5xD) that can be used with this kind of elbow, so when using larger sizes, the application should be limited to light dust or air up to 8".
Available in 3-10" and 12".
