Find expert answers to common questions about our M-CLass vacuum cleaner and extractor range.
  • AnĀ M-Class vacuum cleanerĀ (the "M" standing forĀ MediumĀ hazard) is a specialised dust extraction system certified to capture 99.9% of dust particles.Ā Unlike standard vacuums, M-Class units are a legal requirement underĀ HSE (Health & Safety Executive) regulationsĀ for any professional trade handling "medium-risk" materials.

    They are specifically engineered to manage:

    • Silica Dust:Ā Created when cutting, grinding, or drilling concrete, brick, and mortar.
    • Wood Dust:Ā Particularly from hardwoods and board materials likeĀ MDF.
    • Construction Debris:Ā Including plaster, cement, and paint particles.

    To achieve M-Class certification, the entire machine—not just the filter—must meet strict performance standards.Ā This includes a mandatoryĀ airflow monitoring systemĀ (visual or audible) that alerts the operator if suction falls below 20m/s, ensuring hazardous dust is always being captured at the source before it can be inhaled.Ā At MK Floortec, ourĀ professional M-Class extractorsĀ are independently tested to ensure your site remains compliant and your workforce remains protected

  • The primary difference is the filtration efficiency and safety features.Ā L-Class vacuumsĀ are for low-risk dust (like house dust), whileĀ M-Class dust extractorsĀ are a legal requirement for medium-risk dust, includingĀ silica dust, concrete, and wood dust. M-Class machines must filter 99.9% of dust and, crucially, must feature anĀ audible airflow alarmĀ to alert the operator if suction drops below a safe level—a feature not found on L-Class models.

  • UnderĀ HSE (Health and Safety Executive) guidelines, tradespeople working with materials that produce silica dust—such as stone, brick, and mortar—must use anĀ M-Class certified extractor. Using a standard vacuum allows microscopic, hazardous particles to exhaust back into the air, posing a significant long-term health risk. Using non-compliant equipment can lead to site closures and heavy fines during HSE inspections.

  • This is a built-in power socket found on some models that allows you to plug your sander, saw, or drill directly into the vacuum. When you start your power tool, theĀ M-Class dust extractorĀ automatically triggers, providing seamlessĀ on-tool dust extraction. This ensures that dust is captured at the source before it can become airborne, keeping your workspace clean and compliant.

  • To maintainĀ HSE complianceĀ and 99.9% filtration efficiency, filters should be inspected daily. SomeĀ professional M-Class vacuumsĀ featureĀ automatic filter cleaningĀ (tactile or pulse cleaning), which significantly extends the filter's life by shaking or pulsing dust away from the pleats. While some specialised filters in our range can be washed to restore airflow, they must be allowed to dry completely before being refitted to prevent "blinding" the filter with wet dust.

    However, if theĀ audible suction alarmĀ triggers frequently despite a clear hose and a clean filter, it is time to replace the unit. Always useĀ genuine M-Class replacement filtersĀ from ourĀ Authorised UK HubĀ to ensure the machine remains certified for hazardous dust recovery.

  • TheĀ airflow sensorĀ is a mandatory safety feature for M-Class certification, monitoring the air velocity through the hose to ensure safe dust capture. Depending on the model, this is provided as anĀ audible airflow alarmĀ or a high-visibilityĀ visual airflow indicatorĀ on the machine.

    If the alarm sounds or the indicator signals, it means the airflow has dropped below 20 metres per second—a level insufficient to capture hazardousĀ silica dustĀ safely. This drop in performance is usually caused by a full dust bag, a clogged filter, or a physical blockage in theĀ suction hose or an attached accessory.
