Manufacturing lines suffer when fine dust contaminates products, fouls sensors, or exposes workers. HEPA filtration removes the fraction that ordinary filters miss, especially PM2.5 and below, which stay airborne and travel far.

Pick the right class for the risk

For nuisance dusts, high‑grade M‑Class extraction may suffice. For respirable crystalline silica, wood dust, allergens, or carcinogenic particles, move to H‑Class with H13 or H14 final filtration; H14 is preferred for the highest protection. Match controls to COSHH assessments and process risk.

Control the room, not just the tool

Air scrubbers create cleaner zones around filling lines, CNC cells, or packing areas. Position units to pull air across the process and away from operators. Consider recirculation for energy efficiency where safe, or create negative air during maintenance.

Manage airflow under load

Performance drops as filters load. Size units on under‑load airflow and set inspection intervals. Use prefilters to extend life and maintain pressure. Check for gasket integrity and bypass paths; a perfect media is useless if air leaks round it.

Safe change and verification

Adopt bag‑in/bag‑out or sealed change procedures and label waste correctly. Where critical, verify performance with a particulate meter and keep short logs for trend checks.

Equipment such as MAXVAC Dustblockers can provide continuous high‑efficiency air cleaning around sensitive processes, while tool‑mounted vacuums capture debris at source to reduce loading on room units.
