Choosing the right type of automatic bollard system is essential for balancing performance, reliability, and long-term maintenance. Pneumatic bollards, which use compressed air to operate, offer unique benefits over other automatic bollard types such as hydraulic or electromechanical systems. Here are the key situations where pneumatic bollards are the preferred solution.
1. High-frequency Use Areas
If the bollards need to rise and lower many times a day-like dozens or even hundreds of cycles, pneumatic systems outperform most other types in durability and cool-running operation.
Use pneumatic bollards when you’re managing a busy hotel entrance, parking garage, or business campus. And continuous operation is required without overheating or frequent downtime.
2. Sites Requiring Very Fast Operation Speeds
Pneumatic bollards can typically operate in 3-6 seconds, which is faster than most electromechanical systems. This makes them ideal for emergency access routes, security checkpoints. Use pneumatic system when bollards must deploy or retract very quickly in real time, delays may affect security or traffic flow.
3. Environment Safety Concerns
Hydraulic systems use fluid, which can leak and cause contamination. In contrast, pneumatic systems use compressed air, which is clean and safe. Choose pneumatic bollard when the site must be clean and safe, such as airports, hospitals, historical sites or ecologically sensitive areas.
4. Cold or Harsh Weather Conditions
Pneumatic systems are less affected by freezing winters or extreme climates compared to hydraulic systems, which can thicken and slow down due to cold temperatures.
5. Lower Maintenance Requirements
Pneumatic systems have fewer moving parts. Making them easier to maintain and less prone to wear and tear over time. Compared to hydraulic bollards, it is difficult to find specialized technicians for hydraulic repair.
6. Shallow Excavation Depth
In some places, there are pre-buried pipes or cables underground, and construction conditions do not allow deep excavation. In such cases, pneumatic guardrails can be considered, as their pre-buried openings can be shallow while still providing good protection and impact resistance.
On the other hand, some situations should not to use pneumatic bollards. If you cannot install or maintain a compressed air system, and it will take up space. If you need a self-contained or plug-and-play solution (in that case, electric or electromechanical bollards might be better). If the number of activation cycles is very low(manual bollards or semi-automatic bollards might be sufficient).
