What Kind of Vacuum Cleaner Works for Factory Workshops? 90% of Factories Make the Wrong Choice

Many factories face common troubles with vacuum cleaners: failing to pick up iron scraps and fine dust, clogged filters and burnt motors. The root cause is that they buy household or commercial vacuums, which cannot handle heavy-duty workshop conditions full of dust, oil and metal debris.

Ordinary vacuums have poor heat dissipation, weak filtration, no water/oil resistance and fragile bodies. For workshops, industrial vacuums are required. Follow these 6 selection criteria:

1. Prioritize negative pressure: 15–26kPa for general dust; 26–30kPa for fine dust and aluminum scraps; 30–35kPa for heavy iron scraps and oil sludge.

2. Industrial motors: 220V pure copper motors for intermittent use; 380V three-phase motors for round-the-clock production lines.

3. Multi-stage filtration: Cyclone separation captures large particles; membrane filters trap 0.3μm fine dust. Pulse self-cleaning is optional for heavy dust to avoid secondary dust emission.

4. Wet & dry capability: Equipped with float overflow protection and oil-resistant structure to suck dust, iron scraps, cutting fluid and wastewater.

5. Stainless steel tank: Impact and oil resistant, resistant to deformation.

6. Safety protection: Standard models have leakage and overheat protection; explosion-proof vacuums are mandatory for powder and coating workshops.
