Numatic TRM240 M-Class Site Vacuum Cleaner TradeLine
Numatic TradeLine TRM240 M-Class Site Vacuum Cleaner – HSE Site-Ready Dust Extractor
The Numatic TRM240 TradeLine is the professional's choice for safe, cost-effective, and legally compliant dust extraction. Specifically engineered for the construction and trade sectors, the TRM240 is an M-Class certified vacuum designed to handle "medium-hazard" dusts, ensuring your site remains HSE and COSHH compliant.
Available in 240 volt and 110 volt. Be sure to select your preferred operating voltage above via the operating voltage selector.
Advanced HEPA14 Filtration System
Standard vacuums often exhaust fine, hazardous particles back into the air. The TRM240 features a sophisticated three-stage filtration system that safeguards the health of everyone on site:
- HEPA14 Filter: A long-lasting, washable filter that captures 99.995% of particles as small as 0.3 microns.(type M to BS 603352-69)
- TriTex Primary Filter: Provides a second layer of defence for the motor.
- HepaFlo Dust Bags: Triple-layer NVM-1CH bags provide safe containment and dust-free disposal.
In today's construction landscape, "standard" vacuums are no longer acceptable on-site. The HSE (Health and Safety Executive) has identified silica dust as the second biggest killer of construction workers after asbestos. By using the Numatic TRM240, you aren't just buying a vacuum; you are implementing a critical health and safety control measure.
The "H14" HEPA Difference: 10x More Protection
Most "standard" HEPA vacuums use H13 filters. The Numatic TRM240 utilises H14 HEPA filtration.
- H13 Filters: Allow up to 5,000 particles per litre of air to pass through.
- H14 Filters (TRM240): Allow only 500 particles per litre. This means the TRM240 is 10 times more effective at trapping the microscopic "lung-penetrating" dust that causes Silicosis and COPD.
High-Performance Suction with AirFlo Technology
Powered by a high-efficiency 620W motor, the TRM240 utilises patented AirFlo technology. This ensures consistent, powerful suction even as the bag fills, maintaining an impressive airflow rate of 48 litres per second.
- Low-Flow Indicator: A built-in visual alarm notifies the operator if airflow drops due to a blockage or a full bag—a legal requirement for M-Class safety.
- Dust Containment: The intake features a secure blanking cover, preventing hazardous dust from leaking during transport or storage.
- Extended Reach: Equipped with a 2.8m long-reach hose and a 10m high-visibility yellow cable for maximum mobility.
Built for the Trade: Site-Specific Engineering
The TradeLine range takes the legendary reliability of the "Henry" chassis and optimises it for the rugged environment of a building site.
- High-Visibility Yellow Cable: The 10-metre cable isn't just long; its high-vis colour is a proactive safety feature to reduce trip hazards in dimly lit site environments.
- Internal "Tool Caddy" Storage: No more lost attachments. The rear of the TRM240 features dedicated docking points for the crevice tool and dusting brush, keeping your kit together during transport.
- Large 9L Capacity: In a trade environment, time spent changing bags is time lost. The TRM240 offers 30% more capacity than the compact Henry 160 series, allowing for longer runs on drywall sanding or masonry cleanup
What Materials Can the Numatic TRM240 M-Class Handle?
Under COSHH regulations, an M-Class vacuum is the minimum legal requirement for vacuuming 'medium risk' hazardous dusts. The TRM240 is certified to extract:
- Silica & Masonry: Concrete, brick, cement, and grout dust.
- Wood Dust: Softwood, hardwood (Pine), and MDF.
- Building Materials: Plaster, gypsum, and filling materials.
An M-Class vacuum is the minimum legal requirement recommended by the HSE for vacuuming 'medium risk' hazardous dusts, and it is mandated under COSHH (Control of Substances Hazardous to Health). Using at least an M-Class vacuum is a legal obligation on all construction sites.
What Tools Does The TRM240 Come With?
The TRM240 is equipped with the AS76 accessory kit, ideal for dry debris clean up.
- Stainless steel 3-piece tube set
- 300mm hard floor tool with bristles
- Dusting brush,
- Crevice nozzle
- Multi-size tool adaptor
Comparison: TRM240 vs. Standard Commercial Vacuums
Why choose a TradeLine over a standard model? While the standard commercial Henry (Numatic NRV240 Cylinder Vacuum Cleaner) is a powerhouse, only the TRM240 provides the protection required by law on-site.
| Feature | Numatic TRM240 (M-Class) | Numatic NRV240 (Standard) |
| Dust Rating | M-Class (Medium Hazard) | Standard |
| Filtration Level | HEPA14 (99.995% Efficiency) | Standard Tritex (96% Efficiency) |
| Safety Alarm | Visual Low-Flow Indicator | None |
| HSE Compliance | Legal for Site Use | No (General Cleaning Only) |
| Dust Port | Blanking Cap for Transport | Open Port |
🏗️ Is your site HSE compliant? M-Class filtration is a legal requirement for most UK construction sites to protect against harmful silica dust. If you want to ensure the TRM240 meets your specific site regulations and provides the protection your team needs, read our Numatic TRM240 M-Class Compliance & Value Guide. We break down the technical standards to ensure you stay fully protected and compliant on the job.
Understanding M-Class Vacuum Cleaners: Safety & Compliance Explained
What is an M-Class Vacuum Cleaner?
Why Are M-Class Vacuums Important?
- Worker Health & Safety: Breathing in fine dust over time can lead to severe, chronic respiratory diseases like silicosis (caused by silica dust), asthma, and lung cancer. M-Class vacuums effectively remove these airborne hazards at the source.
- Regulatory Compliance: In the UK and internationally, regulations (such as the HSE's COSHH – Control of Substances Hazardous to Health) mandate the use of certified dust extraction equipment when working with medium-hazard materials. Using compliant machinery ensures your business meets legal requirements and avoids potential fines or work stoppages.
- Site Efficiency & Cleanliness: A superior sealed system means less time spent manually cleaning up mess, improving overall job site professionalism and reducing cross-contamination.
Materials Suitable for M-Class Collection
| Material Type | Common Sources |
|---|---|
| Fine Wood Dust | Sawing, sanding, and cutting softwoods and composite boards (MDF, chipboard). |
| Silica Dust | Drilling, cutting, and grinding concrete, brick, mortar, and stone. |
| Plaster & Drywall Dust | Sanding jointing compounds and cutting plasterboard. |
| Gypsum | Processing certain minerals and construction materials. |
| General Construction Debris | Standard non-flammable building waste. |
The MK Floortec Standard

- High-Grade M-Class Filtration: Equipped with specialised filters (often HEPA or PTFE) designed to capture 99.9% of dust particles, including hazardous silica and wood dust.
- Effective Bag-Disposal Systems: Designed for "low-dust" emptying to prevent workers from inhaling a secondary dust cloud when clearing the machine.
- Robust, Site-Ready Design: Built to withstand the rigours of construction and industrial environments while maintaining a fully sealed system to prevent leaks.
Investing in an M-Class dust extractor is a vital commitment to the long-term health of your workforce and ensures your business remains fully compliant with modern safety legislation.
