Our selection features industry-leading extraction technology from Numatic (TradeLine) and Nilfisk (Attix).

M-Class (Medium Risk) filtration is a legal requirement on UK construction sites for capturing silica dust, wood dust, and mineral debris. Our professional extractors offer a minimum of 99.9% filtration efficiency and feature integrated airflow sensors to alert users if suction drops—a critical safety standard. Whether you need a machine with Power Take-Off for synchronised tool use or a rugged site-ready 110V extractor, we provide the technical expertise and genuine filters to keep your project safe and fully compliant. Explore our M-Class range below.

❓ Frequently Asked Questions: M-Class & HSE Compliance

What is the legal difference between L, M, and H Class vacuums?

The classification refers to the filtration efficiency and the hazard level of the dust being extracted:

  • L-Class (Low Risk): Filters 99% of dust. Suitable for house dust and simple DIY debris (soil, sand).
  • M-Class (Medium Risk): Filters 99.9% of dust. This is the minimum legal requirement for most UK construction sites. It is essential for wood dust and silica dust from concrete, mortar, and brick.
  • H-Class (High Risk): Filters 99.995% of dust. Required for carcinogenic materials like asbestos, lead, and mould spores.

What is "Power Take-Off" and why do I need it?

Power Take-Off (PTO) is an integrated socket on the vacuum that allows you to plug your power tool directly into the extractor.When you trigger the tool (e.g., a wall chaser or sander), the vacuum starts automatically.This ensures you never forget to turn on the extraction, maintaining adust-free environment and ensuring compliance with COSHH regulations

Is M-Class enough for Silica Dust (RCS)?

Yes, under current HSE (Health & Safety Executive) guidelines, M-Class is generally accepted as the minimum standard for on-tool extraction when cutting or grinding concrete and masonry. However, because Respirable Crystalline Silica (RCS) is extremely fine and invisible to the human eye.

How often do I need to change M-Class filters?

For machines used daily on construction sites, we recommend a full filter inspection every3 months and replacement every 12 months—or sooner if the airflow alarm triggers frequently even after a bag change.Using genuine fleece bags will significantly extend the life of your main filter by capturing the bulk of the debris before it reaches the pleats.

Why does my M-Class vacuum have an alarm?

This is a mandatory safety feature for M-Class certification. The alarm (audible or visual) triggers when the air velocity drops below 20 metres per second. This tells the operator that the machine is no longer effectively capturing hazardous dust at the tool head—usually due to a full bag, a blocked hose, or a blinded filter.
