From the moment you transport it from your van to the work area, this vacuum is specifically designed for trades, construction, renovation, and industrial settings where dust is more than just an annoyance—it’s a regulated hazard. With built-in M-Class certification, the TRM240 ensures that you fulfill your legal obligations to manage worker exposure to harmful dust.
At its core, it features a long-lasting 620W motor that is designed to endure heavy trade usage. This power generates an airflow of 48 L/sec (motor only) and a sealed suction of 2,300 mm, providing strong suction to effectively remove plaster dust, wood particles, grit, and general site debris.
When it comes to filtration, the TRM240 truly showcases its trade qualifications. It includes a three-stage system featuring a washable HEPA (H14) filter, a TriTex primary filter, and HepaFlo dust bags. The HEPA filter is rated to capture 99.995% of particles at 0.3 microns, which means it effectively filters even the finest silica dust and wood particulates.

What Type of Dust can the TRM240 Handle?
An M-class vacuum cleaner is designed to safely collect medium-hazard dusts that have an occupational exposure limit value greater than 0.1 mg/m³. This certification is often a legal requirement (under COSHH regulations) on UK construction sites and in workshops.
Common materials and dust types that an M-class vacuum can collect include:
-
Wood dust: This is a primary application, especially from hardwoods (like oak and beech), softwoods, and manufactured boards like MDF and chipboard, which can cause respiratory issues or cancer if inhaled long-term.
-
Silica dust: Generated from cutting, drilling, or grinding materials that contain quartz, such as concrete, brick, mortar, stone, and tile cement.
-
Plaster and drywall dust: Common in renovation and building work.
-
Paint and coating particles: Includes dust from sanding paint (excluding lead-based paints, which require H-class vacuums) and other repair fillers.
-
Plastics and ceramics dust: Particles generated from working with these materials.
-
General construction and renovation debris: Effectively manages various mixed dusts found on typical building sites.
-
Mineral dust and metal dust: From grinding and cutting various metals and minerals.
For more information on the specific materials requiring this level of filtration, the HSE website provides comprehensive guidance.
Is the TRM240 Suitable for Asbestos or Other High-Hazardous Materials?
Note: An M-class vacuum is not suitable for high-hazard materials like asbestos, carcinogenic substances, or pathogenic particles, which require a specialised H-class vacuum cleaner for safe extraction.
How do I maintain the Filters and Bags?
The Hepaflo NVM-1CH Dust Bag should be changed frequently, and filters should be kept clean to ensure optimal performance. The HEPA 14 filter is long-life and washable.
