Cordless & Battery Dust Extraction — M-Class and H-Class Without a Mains Supply
Cordless and battery dust extraction — M-Class and H-Class without a mains supply
Cordless and battery-powered dust extractors carry the same COSHH compliance obligation as corded machines — M-Class or H-Class certification is a property of the filtration standard, not the power source. What changes with battery operation is the ability to deploy COSHH-compliant extraction at the point of work without needing a 110V transformer or mains socket at that location. On construction sites, maintenance rounds, housing association stock and NHS estate, that operational flexibility is increasingly the deciding factor.

Why cordless M-Class matters on site
On a live construction or refurbishment site, a trailing cable from a corded extractor creates a trip hazard, limits reach, requires a 110V transformer or confirmed mains supply at the point of use, and adds setup time every time the operative moves. On maintenance contracts where operatives work across multiple locations in a day — housing association stock, NHS estate, commercial premises, schools — cable management overhead accumulates fast.
A cordless M-Class extractor eliminates those constraints. The operative takes it into a ceiling void, along a corridor, up a stairwell, into a plant room — exactly where the cutting, grinding or drilling work is happening — without any power supply at the point of use. The M-Class filtration standard is identical. The COSHH compliance position is the same. The 14-month LEV examination requirement under COSHH Regulation 9 applies equally to cordless machines used as local exhaust ventilation.

When you need M-Class vs H-Class in a cordless machine
M-Class cordless extraction is the correct specification for the majority of construction and maintenance dust-generating work — cutting, grinding, drilling and chasing of concrete, brick, mortar, block and general construction materials where the COSHH risk assessment confirms M-Class is sufficient. The WEL for respirable crystalline silica is 0.1 mg/m³ and M-Class extraction at source is the primary engineering control.
H-Class cordless extraction is required for asbestos-containing materials under CAR 2012, for significant mould remediation, for carcinogenic dusts, and for ICRA-classified clinical environments. In pre-2000 buildings where asbestos status has not been confirmed by survey, H-Class should be the default for any dust-generating work that penetrates existing building fabric.

V-TUF cordless dust extraction — the RUCKVAC range
V-TUF's cordless dust extraction range is built around the RUCKVAC backpack format — worn on the back, hands-free, no trailing cables, M-Class HEPA filtration. The backpack configuration is the correct format for cordless on-tool extraction: it stays close to the operative as they move, the hose runs directly to the tool, and there is no floor-standing unit to trip over or reposition.
V-TUF RUCKVAC-ION — cordless M-Class backpack, 300W brushless
Battery-powered M-Class backpack dust extractor. 300W brushless digital motor, H13 HEPA filtration, 25.9V replaceable battery system, 32mm heavy-duty anti-crush hose. The primary V-TUF specification for COSHH-compliant cordless dust extraction on construction sites and maintenance rounds where mains power is not available at the point of work.

V-TUF RUCKVAC HSV — corded M-Class backpack, 110V and 240V
Corded M-Class backpack vacuum for site and maintenance use where a power supply is available. H13 HEPA filtration, lightweight backpack format, suitable for construction sites on 110V site supply, school and college D&T workshops, and any environment requiring COSHH-compliant M-Class extraction in a compact, mobile format. Available in 110V site-safe and 240V mains variants.

Where cordless M-Class extraction is used
Construction sites — no transformer needed at the point of work
110V CTE supply is the mandated voltage for portable electrical equipment on UK construction sites under the Electricity at Work Regulations 1989. A cordless M-Class extractor bypasses the transformer requirement entirely — it carries its own power supply and is site-safe without any electrical supply at the work location. RAMS documentation should specify the extraction class (M-Class) and note that the machine is cordless — the compliance obligation is identical to a corded 110V machine.

Housing association and social housing maintenance
Maintenance operatives working across housing association stock — void clearance, planned maintenance, mould remediation — move between properties throughout the day. A cordless M-Class backpack eliminates the need to locate a power socket in each property and removes cable trip hazard in occupied homes. For mould remediation work, M-Class is the minimum extraction standard under COSHH; H-Class is required where contamination is severe.

NHS estate and healthcare construction
Maintenance and building works inside occupied healthcare facilities require M-Class or H-Class extraction under ICRA. A cordless machine removes one source of infection risk — trailing cables in corridors and patient areas — and simplifies deployment in the confined, access-controlled spaces typical of NHS estate work.

Heritage buildings and listed properties
Refurbishment work inside listed buildings and heritage properties frequently involves working without convenient power access — stone floors, historic wiring, no socket at the point of work. Cordless M-Class extraction maintains COSHH compliance without the need for extension cables across sensitive floors or historic interiors.
