### **Cons**

1. **Dependence on Compressed Air Supply**

- Requires a **reliable and properly maintained pneumatic system** (compressor, filters, dryers, and regulators).

- **Air quality issues** (moisture, contaminants) can cause **premature wear** or malfunctions.

- **Power outages** (if the compressor is electric) can halt operations unless backup power is available.

2. **Slower Response Time Compared to Electric Actuators**

- **Pneumatic systems** generally have **higher inertia** than electric or hydraulic counterparts, leading to **slower acceleration and deceleration**.

- **Not ideal for high-speed applications** (e.g., rapid cycling in packaging machinery).

3. **Limited Force Output at Low Pressures**

- While strong at higher pressures, **performance degrades at lower pressures**, which may require **larger actuators or boosters** for heavy-duty tasks.

- **Not suitable for ultra-high-force applications** without additional support (e.g., mechanical advantage systems).

4. **Noise and Vibration**

- **Compressed air release** can generate **audible noise and vibration**, which may be problematic in **quiet environments** (e.g., laboratories, offices).

- **Mitigation requires sound-dampening enclosures or mufflers**.

5. **Higher Initial Cost Than Basic Electric Actuators**
