---
### **Cons**
1. **Dependence on Compressed Air Supply**
- Requires a **reliable air compressor and filtration system** to prevent contamination or pressure fluctuations, which can affect performance.
- **Air leaks** can reduce efficiency and increase energy consumption.
2. **Limited Torque at Low Speeds**
- Pneumatic actuators may **lose torque at very low speeds** due to internal friction, which can be a limitation in high-precision or slow-motion applications.
- Requires **proper sizing** to avoid stalling under load.
3. **Noise and Vibration**
- Pneumatic systems can generate **audible noise and vibration**, which may be problematic in **quiet environments** (e.g., laboratories, cleanrooms).
- Requires **sound-dampening measures** (e.g., mufflers, vibration isolators) in sensitive applications.
4. **Slower Response Than Electric Motors (in Some Cases)**
- While pneumatic actuators are **fast for their size**, they may not match the **instantaneous response** of servo motors in ultra-high-speed applications.
- **Air delay** (time for pressure to reach the actuator) can introduce slight lag.
5. **Temperature Sensitivity**
- Performance can degrade in **extreme temperatures** (very hot or cold), as air viscosity and seal flexibility are affected.
- Requires **environmental considerations** when selecting the actuator for outdoor or high-temperature applications.
6. **Higher Initial Cost Than Basic Electric Alternatives**
