🛡️ Buy M-Class Vacuum Cleaners & HSE Compliant Dust Extractors

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.

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

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.

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.

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.
