Choosing the right vacuum for construction work isn’t as simple as it looks. Each tool generates a different type of dust, and not every vacuum can handle it.In our workshop we see the same issues every week: saturated filters, burnt‑out cartridges, vacuums that lose suction, and machines that simply aren’t designed for the amount of dust produced by porcelain cutting, wall chasing or concrete work.

This guide explains which vacuum you should choose depending on your tool and your job, so you can work safely, efficiently and without constant breakdowns..

1. Class L: Light‑duty dust

Suitable for:

• Sanders

• Woodworking

• Non‑abrasive dust
  

• Light renovation work

Advantages: affordable, lightweight. Limitations: not suitable for porcelain, concrete or general construction dust.

2. Class M: The professional standard for 2026

Suitable for:

• Grinders

• Wall Chasers

• Porcelain cutting

• Concrete

• Brickwork

• Mortar and general construction work

Advantages:

• Filters fine dust effectively
• Reduces saturation

• Compatible with high‑airflow tools

If you work in construction, Class M is the correct choice.

3. Class H: Hazardous or ultra‑fine dust

Suitable for:

• Asbestos

• Chemical dust

• Indoor demolition

• Materials with very fine silica content

Not common in general construction, but essential for specialised work.

4. Recommended minimum airflow

If you use an angle grinder or wall chaser, you need a vacuum with:
≥ 3.500 L/min of real airflow Anything below that means:

• Saturation
• Loss of suction
• Dust clouds
• Overheating
• Poor cutting performance

5. Tool compatibility matters

Before choosing a vacuum, always check:

• Hose diameter

• Connection system

• Automatic filter cleaning

• Real suction power (not just theoretical numbers)

A narrow hose can ruin the performance of even a high‑end vacuum.

Conclusion

The right vacuum doesn’t just help you comply with regulations — it gives you cleaner cuts, less dust, fewer breakdowns and a more efficient workflow.
