Dust extraction at the source using better hoods duct velocity and pressure control

Dust extraction works best when the capture hood is designed around the task. Poor hood geometry leads to escape dust even with a powerful fan.

Source capture fundamentals

• Place hoods close to generation point

• Maintain adequate capture velocity

• Use smooth transitions and proper duct velocity

• Control pressure losses and leakage

Common mistakes

• Oversized ducts with low velocity and settling

• Long runs with unnecessary restrictions

• Underestimating filter pressure drop
