Choosing the right dust shroud matters because it is the difference between clean capture at source and a dusty, non-compliant job. For masonry, mortar raking, and surface prep, a well-matched shroud allows the vacuum to do its job, reduces airborne respirable crystalline silica (RCS), and improves visibility and finish quality.

Start with fit and compatibility

Confirm the shroud is designed for your grinder size (110–125 mm) and the task: cup wheels for grinding and segmented discs for raking or cutting. Check how the shroud attaches (band clamp, collar, or dedicated guard replacement) and ensure there is no wobble. A snug, concentric fit keeps the seal even and capture efficient.

Seal quality and edge access

Look for a continuous skirt or brush ring that maintains contact with the surface without snagging. A worn or gapped skirt leaks dust immediately. If you work to edges, a hinged or swing-away front helps you get flush to walls without removing the shroud. Clear sight windows can aid line-keeping while maintaining enclosure.

Extraction interface

Match the extraction port to your hose and vacuum. Common hose sizes are 32 or 36 mm; the aim is a tight, anti-static connection with minimal bends. Keep hoses as short and smooth as practical and avoid crushed sections. Pair the shroud with an industrial vacuum that maintains adequate airflow under load and has filtration suited to your dust risk: M-Class for most construction dusts, H-Class with HEPA (H13/H14) where fine or carcinogenic dusts are present. Many contractors successfully pair shrouds with MAXVAC industrial vacuums to maintain reliable on-tool capture on masonry work.

Set-up checks

Before cutting, seat the shroud square to the surface and run the grinder at speed to confirm there is no rubbing. Test capture on a small area and watch for escaping plumes. If dust escapes, slow the feed rate, improve the seal, or step up vacuum performance. Replace frayed brushes and keep the shroud clean so the skirt can flex as designed.

Practical takeaways

• Choose a shroud made for your wheel type and grinder size.
• Prioritise a continuous, intact skirt and a solid, wobble-free mount.
• Use anti-static hose; minimise hose length and tight bends.
• Select a vacuum with suitable filter class and airflow under load.
• Test on a small patch and adjust speed and seal before full production.

Good shrouds are simple: secure fit, reliable seal, and a clean path to a capable vacuum. Get those right and you will cut dust, stay closer to HSE expectations, and work faster with fewer clean-ups.
