In **on-site machining operations**—beveling, facing, flange repair, deburring or grinding—**pneumatic** drive systems remain a benchmark: no electrical overheating, safe for explosive environments (**ATEX**), low maintenance, and reliable under **harsh working conditions**.

However, **replacing an original pneumatic motor** can be difficult when it is no longer available, limited in performance, or simply hard to obtain within a reasonable lead time.

Modec **vane air motors** are designed with **planetary gear systems** to ensure efficient torque transmission, strong mechanical robustness, and excellent load endurance over time to withstand **demanding industrial conditions**.

If you are looking for an **alternative to a pneumatic machining** motor already used in your process or custom-built machines, modec offers lightweight, high-performance, and quickly available solutions that adapt to your on-site constraints.

 

## **Selecting a ~3.5 HP Pneumatic Motor: What Criteria Should You Consider? **

If your current motor has characteristics similar to the following, you are within the range of motors **we replace very frequently**, even when the original models are no longer available or difficult to procure:

- **✅Torque at Max power**: between **240** and **380 Nm (177 lb.ft -280 lb.ft)**
- **✅Stall torque** : above  **480 Nm (354 lb.ft)**
- **✅Free speed** : usually between **150 - 210 rpm**
- **✅Speed at Max Power :** about **100 rpm**
- **✅Weight** : below** 9 kg (19.75 lb)**
- ✅Typically used for : **beveling, facing, flange machining, portable on-site machining**

➡️ In this configuration, you can get more with the best modec equivalent :  ** [MTS 30 XT 054](https://modec.fr/en/air-motors/motors/mts-30/).** This model is the most popular among users seeking a motor comparable to a ~2600 W pneumatic motor used in p**ipework**. However, depending your needs, it may exist others choices more suitable to your application. 

## **Choosing the Most Suitable Alternative: 3 Non-Reversible ~3.5 HP Air Motors for Pipe machining**

| **Main requirement** | **Recommended model** | **Why ?** |
| --- | --- | --- |
| Increase machining speed | [MTZ 25 XT 054](https://modec.fr/en/air-motors/motors/mtz-25/) | Higher free speed for faster cutting |
| Increase torque under load | [MTZ 25 XT 077](https://modec.fr/en/air-motors/motors/mtz-25/) | Higher stall torque, adequate for harder materials |
| Find a superior alternative to current motor | [MTS 30 XT 054](https://modec.fr/en/air-motors/motors/mts-30/) | Higher power for a better speed and torque |

### Overview of the technical specifications of the equivalents at 6.2 bars (90 psi)

| **Model** | **Max Power ** **(HP)** | **Reversible** | **Free speed (rpm)** | **Speed @ Max.** **Power (rpm)** | **Torque output @ Max. Power (Nm (lb.ft))** | **Stall torque (Nm (lb.ft))** | **Weight** **(kg (lb))** |
| --- | --- | --- | --- | --- | --- | --- | --- |
| [**MTZ 25 XT 054**](https://modec.fr/air-motors/motors/mtz-25/) — Speed priority | 3.6 | No | 208 | 104 | 249 (183) | 399 (294) | 6,1 (13.45) |
| [**MTZ 25 XT 077**](https://modec.fr/air-motors/motors/mtz-25/) — Torque priority | 3.6 | No | 145 | 73 | 357 (263) | 571 (421) | 6,1 (13.45) |
| [**MTS 30 XT 054**](https://modec.fr/air-motors/motors/mts-30/) — Versatility | 4.3 | No | 186 | 93 | 330 (243) | 638 (470) | 7,3 (16.10) |
