All DARM arms have a fitting for dust extraction, couplings for compressed air distribution and electrical sockets to power the tools required for the various processes.*** An extraction arm is necessary for a body shop that has a permanent extraction system for dust produced when sanding vehicles; in fact, arms let you **move the utilities from the walls to the work station** and easily reach the **back** of the vehicle. ![](https://blog.worky-italy.com/hubfs/KIRO/Imported_Blog_Media/braccio-aspirante-per-carrozzeria-l-alleato-contro-le-polveri-di-carteggiatura_i6168-kBZvd4o-l1-n1-1-2.jpg) ## 4 extraction arm models for body shops At WORKY we have developed a series of [extraction arms for body shops](https://blog.worky-italy.com/en/extraction-of-dry-sanding-dust?hsLang=en-gb): **DARMs** – **Dry Sanding Arms** – are lightweight arms, made of rustproof **aluminium**; they include a **fitting** for sanding dust extraction, some **couplings** intended for compressed air distribution and **electrical sockets** to power the tools required for the processes. **4 different models** are available, let's take a look at each and what distinguishes them. ## DARM3 and DARM3SU DARM3 and DARM3SU are both **3 metres** long and thus perfect to move electrical and pneumatic utilities from the wall to the work station. - In [DARM3](https://blog.worky-italy.com/en/extraction-of-dry-sanding-dust/arms/self-supporting-3-mt-arm-darm3?hsLang=en-gb), the service distribution **panel** and dust extraction **mouth** are **built into** the arm frame. Available with both automatic and manual start. - In [DARM3SU](https://blog.worky-italy.com/en/extraction-of-dry-sanding-dust/arms/self-supporting-3-mt-arm-darm3su?hsLang=en-gb), the **panel** is **external** and connected to the end of the arm with a 1.5m long flexible hose, thus further expanding the extraction arm's range of action for the body shop. It is also available with both automatic and manual start. ![](https://blog.worky-italy.com/hubfs/KIRO/Imported_Blog_Media/braccio-aspirante-per-carrozzeria-l-alleato-contro-le-polveri-di-carteggiatura-2_i6169-ktBqusx-l1-n1-1-2.jpg) ## DARM6L and DARM6SU DARM6L and 6SU, on the other hand, are **6 metres** long: the greater length is designed to reach the **back of the vehicle**, facilitating extraction. - [DARM6L](https://blog.worky-italy.com/en/extraction-of-dry-sanding-dust/arms/self-supporting-6-mt-arm-darm6l?hsLang=en-gb), like DARM3, has both electric and pneumatic utility distribution and the dust extraction mouth built into the extraction arm frame. Flexibility is enhanced by the central junction and **halogen spotlight** mounted on the end to directly light up the station; - [DARM6SU](https://blog.worky-italy.com/en/extraction-of-dry-sanding-dust/arms/self-supporting-6-mt-arm-darm6su?hsLang=en-gb) has a panel on the end connected by a flexible hose; what's more, it has a central junction that lets you rotate it at will. **There are 3 SU versions**: with manual start (SU), with automatic start (ASU) and with automatic start with extraction cut-off when not used (6ACSU). ![](https://blog.worky-italy.com/hubfs/KIRO/Imported_Blog_Media/braccio-aspirante-per-carrozzeria-l-alleato-contro-le-polveri-di-carteggiatura-3_i6167-kFV8LFi-l1-n1-1-2.jpg)   [Learn more about all WORKY extraction arm features for body shops: download the catalogue or contact us!](https://blog.worky-italy.com/en/company/contact-us?hsLang=en-gb)   --- #### [Earth-moving vehicle exhaust extraction arms Previous Post](https://blog.worky-italy.com/en-gb/automotive/earth-moving-vehicle-exhaust-extraction-arms?hsLang=en-gb) #### [Oil dispensing systems: computerised is better Next Post](https://blog.worky-italy.com/en-gb/automotive/oil-dispensing-systems-computerised-is-better?hsLang=en-gb) [![CTA C1 - verticale gas di scarico - EN - gennaio 2025 v2](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/26256811/interactive-102029206998.png)](https://cta-eu1.hubspot.com/web-interactives/public/v1/track/redirect?encryptedPayload=AVxigLLSN%2BOprhysqBVVPbif3ifDDbsENQTzk%2BlWUVWbiu6B3wrd7q0nj1hjR346kErnm7p2IBJXghKytBhuGIFgUDqe%2B55vE5EfZzvPNNKRP4Ws3V9BC8RDjgfisJ%2F2qtpPxUmH9Iw1OzUbiUU%2Bk5YAuMq9oHEbPggjfxL6GIa9sqp3wYYmi8YFHbr4DgZT75S39yVQBqkpiQsubgvXEIu4CMc6WDvgU1dASH4DtPKzFbep&webInteractiveContentId=102029206998&portalId=26256811) ##### Blog WORKY Automotive Subscribe to WORKY's Automotive blog and stay updated! ### Categories - [automotive (43)](https://blog.worky-italy.com/en-gb/automotive/tag/automotive) - [exhaust gas extraction (39)](https://blog.worky-italy.com/en-gb/automotive/tag/exhaust-gas-extraction) - [exhaust fumes extraction systems (19)](https://blog.worky-italy.com/en-gb/automotive/tag/exhaust-fumes-extraction-systems) - [fume extraction systems (15)](https://blog.worky-italy.com/en-gb/automotive/tag/fume-extraction-systems) - [car workshop (12)](https://blog.worky-italy.com/en-gb/automotive/tag/car-workshop) ### Popular Posts 21 May, 2021 [Car workshop design: best practices for maximum efficiency](https://blog.worky-italy.com/en-gb/automotive/worky-s-car-workshop-design-process?hsLang=en-gb) 07 Apr, 2022 [Exhaust fume extraction: the benefits of modern systems](https://blog.worky-italy.com/en-gb/automotive/exhaust-fume-extraction-benefits?hsLang=en-gb) 30 Jan, 2025 [How to choose the right exhaust fumes extraction systems](https://blog.worky-italy.com/en-gb/automotive/choose-right-exhaust-fumes-extraction-systems?hsLang=en-gb) 24 Feb, 2026 [Portable exhaust gas extractor: the flexible solution for today’s garage](https://blog.worky-italy.com/en-gb/automotive/portable-exhaust-gas-extractor-workshop-guide?hsLang=en-gb) [![worky](https://blog.worky-italy.com/hubfs/Images_DEA_Worky_November2024/Images/footer-Logo.svg "worky")](https://ronb33.sg-host.com/) We work alongside your business to make your work environment unique, functional and well-organised, perfectly suited to your needs.
