### **Cons**
1. **Dependence on Compressed Air Supply**
- Requires a **reliable compressed air source**, which adds infrastructure costs (compressors, filters, dryers).
- Power outages or air supply failures can **halt operations**, unlike electric actuators that may have backup power options.
2. **Limited Continuous Torque at Low Pressures**
- At **0.7 MPa**, the actuator may struggle with **high-load applications** requiring sustained torque. Higher-pressure models (e.g., 1.0 MPa or 1.6 MPa) may be needed for demanding tasks.
- **Stiction (friction at rest)** can reduce efficiency in low-speed applications.
3. **Sensitivity to Contaminants**
- Compressed air must be **properly filtered** to prevent **particle buildup** in seals and cylinders, which can degrade performance over time.
- Moisture or oil in the air supply can **corrode internal components**.
4. **Slower Response Than Electric Actuators**
- Pneumatic systems have **inherent delay** due to air compression and expansion, making them **less ideal for high-speed or precise timing applications** compared to servo motors.
- **Overshoot and oscillation** can occur if not properly damped.
5. **Higher Noise in Some Configurations**
- Without proper **sound dampening**, the actuator can produce **audible clicking or hissing noises**, which may be problematic in sensitive environments.

- Requires **regular inspections** to prevent pressure drops.
9. **Less Suitable for Dynamic Positioning**
- Unlike electric servo actuators, pneumatic systems **lack fine control for dynamic movements** (e.g., smooth acceleration/deceleration).
- Better suited for **on/off or step positioning** rather than continuous motion.
10. **Training and Expertise Required**
- Proper **pneumatic system design and troubleshooting** require specialized knowledge, which may not be available in-house for all companies.
