***DARM is a synonym for our body shop extraction arm excellence: it removes even the smallest grain of dust freed in workshops and body shops when sanding or performing similar work. 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.

## 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/us/extraction-of-sanding-dust?hsLang=en-us): **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/us/extraction-of-sanding-dust/arms/self-supporting-10-ft-arm-darm3?hsLang=en-us), 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/us/extraction-of-sanding-dust/arms/self-supporting-10-ft-arm-darm3su?hsLang=en-us), 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.

## 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/us/extraction-of-sanding-dust/arms/self-supporting-20-ft-arm-darm6l?hsLang=en-us), 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/us/extraction-of-sanding-dust/arms/self-supporting-20-ft-arm-darm6su?hsLang=en-us) 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).
