Industrial Dust Extractors & Industrial Vacuum Cleaners

M-Class & H-Class Compliance

Correct classification is essential for UK construction environments and health protection.

M-Class (Medium Hazard)

• Required for silica, concrete, mortar, plaster and wood dust
• Minimum standard on most UK sites
• Designed to maintain adequate transport velocity in the hose to prevent dust settlement

H-Class (High Hazard)

• Required for asbestos, lead-based coatings and carcinogenic particulates
• Sealed containment system
• Incorporates HEPA H14 filtration
• 99.995% filtration efficiency

For a more detailed explanation of workplace exposure limits and safe working practices, see our Silica Dust Control & RCS Compliance Guide.

Most PWM extractors can be supplied in H-Class configuration on request.

 

Filter Cleaning Systems Explained

Extraction performance depends on filter condition — not just motor wattage.

As fine dust loads onto the filter:

• Airflow reduces
• Hose velocity drops
• Tool capture efficiency falls
• Downtime increases

PWM systems use duty-matched cleaning systems:

Manual Reverse Pulse – TV50

Operator-activated air pulse cleaning for handheld grinding and chasing.

Assisted Shaker (Push-Button Activated) – S13 Shake & SP13-2

Push-button activated shaker restores airflow without opening the unit.

Manual Shaker – Optim 120 / TV150 / Planet Turbine Systems

Heavy-duty shaker mechanism suited to sustained grinding environments.

Semi-Automatic Shaker – Coynco 180MD / 280MD

Manufacturer-designed assisted shaker system for light to medium-duty work.

Fully Automatic Cleaning – Coynco Iclean

Continuous automatic cleaning for high dust output.

Automatic Compressed Air Jets – R2D2

Industrial air-jet cleaning for turbine-based high-production and shot blasting environments.

If you are working in heavy dust environments and experiencing frequent filter loading, pairing your extractor with a Cyclone Dust Separator can remove up to 98% of debris before it reaches the filter, significantly reducing cleaning frequency.

Shot blasting typically requires high airflow and lower vacuum. Grinding applications require stable vacuum performance at the tool.

 

System Approach — Point Extraction

Effective dust control relies on point extraction — capturing dust at the source before it becomes airborne.

Maximum capture begins at the guard. Explore our range of Grinding Cowls and Dust Guards to ensure the tool connection is properly sealed and matched to your extractor.

 

Hose Diameter & Transport Velocity

Correct hose selection is not simply about fitment — it directly affects transport velocity, airflow stability, and overall dust capture efficiency.

Typical hose pairings:

• Ø32–38 mm – High-velocity extraction for handheld power tools, sanders and wall chasers.
• Ø50 mm – Balanced airflow for mid-size floor grinders and higher dust volume recovery.
• Ø70 mm – Industrial-scale extraction for large planetary grinders and turbine systems.
• Ø125 mm – Heavy-duty recovery for shot blasting and bulk material handling.

Why Hose Size Matters

Maintaining adequate transport velocity within the hose prevents dust settling and internal restriction. If hose diameter is too large for the extractor’s airflow output, velocity can drop and dust can settle inside the line. Conversely, fitting a hose that is too small on a high-airflow turbine system can restrict airflow and reduce capture efficiency.

PWM supplies reducers and adaptor kits (e.g., Ø70→Ø50, Ø50→Ø32) via our vacuum hoses, tools, floor wands and connectors range, to correctly match the extractor to the tool.

 

Common Causes of Performance Drop

If suction reduces, check:

• Drum, lid or seal misalignment (often after emptying or transport)
• Blocked/loaded filters (use the cleaning system correctly)
• Split, crushed or undersized hoses
• Failed or partially failed motors
• Poor site power supply
• Damaged or poorly fitted tool guards (loss of point extraction)

Performance issues are frequently system-related rather than motor failure.

 

Servicing, Repairs & Long-Term Support

Frequently Asked Questions

Can I use a dust extractor for general hoovering?

Yes. With a suitable floor head and wand, industrial extractors are effective for general site cleaning. Suitable accessories are available in our vacuum hoses, tools, floor wands and connectors range.

What maintains airflow during operation?

Clean filters, correct hose diameter, good system sealing, and a matched tool guard connection — not motor wattage alone.

110V or 400V — what should I choose?

110V is standard on UK construction sites. 400V turbine systems are typically selected for larger grinders, continuous production work and shot blasting.
