DEWALT DWV905M-QS 38L M-Class Wet & Dry Dust Extractor – 1400W, 25kPa Suction, Auto Filter Cleaning, Wireless Tool Control – 230V

Overview

Keep demanding jobsites cleaner and control hazardous construction dust more effectively with the DEWALT DWV905M-QS 38L M-Class Wet & Dry Dust Extractor. Built for professional workshops, construction sites and trade environments, it combines a powerful 1400W motor, 25kPa negative pressure and high-volume airflow with M-Class filtration for dust generated from materials such as wood and mineral products.

The DWV905M is designed to maintain suction while you work. Its automatic dual-filter cleaning system cleans one filter every 30 seconds, helping maintain consistent airflow without repeatedly stopping to clean the filters manually. An audible alarm also warns when airflow performance falls below the required level.

With a generous 38L dry tank capacity, 18.4L wet capacity and a long 4.6m antistatic hose, it is equally useful for extracting fine dust directly from compatible power tools or cleaning up dirt and liquids around a worksite.

The extractor also supports DEWALT Wireless Tool Control, allowing compatible cordless tools or the supplied remote key fob to activate the extractor without repeatedly walking back to the machine. A built-in power take-off socket provides automatic start/stop operation with compatible corded tools.

Key Features & Benefits

• Control M-Class Construction Dust More Safely – The DWV905M meets M-Class extraction requirements, making it suitable for professional applications involving potentially harmful dust such as hardwood, softwood and mineral dust. DEWALT's German specification identifies M-Class applications at occupational exposure limits of ≥0.1mg/m³.
• Maintain Strong Suction Throughout the Job – An automatic filter-cleaning system activates every 30 seconds, alternately cleaning the filters so airflow can remain consistent during prolonged extraction work.
• Get More Extraction Performance Than the Previous Generation – DEWALT states that the DWV905M provides approximately 16% more airflow and 11% more pressure than the DWV902M, giving it greater extraction capability while retaining the proven platform design.
• Handle Both Dust and Liquid Clean-Up – Full Wet & Dry capability means one machine can extract construction dust, debris and compatible liquids instead of requiring separate vacuums for different jobs.
• Work Longer Before Emptying the Tank – The spacious 38L container provides substantial dry-material capacity, while wet collection capacity is rated at approximately 18.4L.
• Know When Extraction Performance Drops – An integrated audible alarm warns the operator if airflow falls, helping indicate a blockage, full container or other condition affecting extraction performance.
• Start the Extractor from Your Cordless Tool – Wireless Tool Control lets compatible DEWALT equipment communicate with the vacuum so extraction can start and stop automatically alongside the tool.
• Control the Vacuum Remotely – The supplied Wireless Tool Control key fob lets you start or stop extraction from a distance, particularly useful when the extractor is positioned away from the immediate work area.
• Connect Corded Tools Directly – A built-in 2200W power take-off socket on the QS model allows compatible mains-powered tools to be connected for automatic extractor activation.
• Clear Residual Dust After the Tool Stops – Automatic start/stop control keeps the extractor running for approximately 15 seconds after the connected tool stops, helping clear dust remaining within the hose and extraction path.
• Adjust Suction to Suit the Application – Variable suction control lets you reduce or increase airflow depending on the connected tool, material and working conditions rather than always operating at maximum power.
• Connect Quickly to Compatible DEWALT Tools – The AIRLOCK system creates a secure connection between the hose and compatible power tools, helping reduce accidental disconnection and improving dust-extraction efficiency.
• Reach Further Around the Work Area – A long 4.6m antistatic hose provides useful working range around benches, saw stations and larger work areas while helping reduce static build-up.
• Move a 38L Extractor More Easily – A telescopic transport handle and heavy-duty wheels improve manoeuvrability around construction sites despite the machine's substantial capacity.
• Built for Harsh Site Conditions – The extractor carries an IPX4 protection rating, adding resistance against water splashes encountered in demanding working environments.
• Expand Storage Around the Extractor – An optional adapter system allows compatible TSTAK and TOUGHSYSTEM storage boxes to be mounted with the extractor, helping turn it into a more organised mobile workstation.

Why Choose This Product

The DEWALT DWV905M-QS is built for professionals who need more than a conventional workshop vacuum.

Its major advantage is the combination of M-Class dust control and automatic filter cleaning. Fine construction dust can rapidly clog an ordinary filter and reduce extraction performance. The DWV905M combats this by automatically cleaning its filters every 30 seconds, helping maintain airflow while demanding cutting, grinding, sanding or drilling work continues.

It is also designed to integrate directly into a professional power-tool workflow. Compatible cordless tools can trigger the vacuum wirelessly, corded tools can use the built-in power take-off socket, and the supplied remote gives you another way to activate extraction without returning to the machine.

The large 38L tank, 25kPa suction pressure and 4.6m hose make it capable enough for substantial jobs, while heavy-duty wheels and a telescopic handle keep it mobile between work areas.

For trades working regularly with wood, concrete, masonry or other dust-producing materials, the DWV905M provides a professional extraction solution focused on sustained suction, M-Class compliance and tool integration.
