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

Dust extraction is only effective when the hood actually captures the dust plume. If hood placement and geometry are poor the dust escapes even with high fan power. A strong system starts with source capture and ends with stable filtration.

Source capture fundamentals

• Keep hoods close to the generation point

• Maintain capture velocity where the dust is released

• Preserve transport velocity inside ducts

• Account for pressure losses across fittings and filters

Common issues

• Oversized ducts that slow velocity and cause settling

• Long duct runs with unnecessary elbows

• Underestimated filter pressure drop over time

Saf Teknik projects focus on pressure realistic engineering and practical layouts so extraction remains strong months after commissioning.
