Compressors Vs Stirrup Pumps Vs 300BAR Cylinders

Choosing the Best Method to Refill Your Air Rifle: Stirrup Pumps vs Electric Compressors vs 300 BAR Dive Cylinders

Refilling your PCP air rifle is an unavoidable task. In the UK, the main methods for refilling air rifles are Stirrup Pumps, Electric Compressors, and 300 BAR Dive Cylinders. Each has its own advantages and disadvantages. Let’s explore these options to help you decide which one suits your needs best.

Stirrup Pumps

Pros:

  1. Affordable: Stirrup pumps are generally the least expensive option. They don’t require additional equipment or power sources.
  2. Portable: Lightweight and easy to carry, making them ideal for use in the field.
  3. Simple to Use: Straightforward operation without complex machinery.

Cons:

  1. Physically Demanding: Requires significant physical effort, which can be tiring.
  2. Time-Consuming: Slower compared to other methods, which might be inconvenient if you’re in a hurry.

Electric Compressors

Pros:

  1. Convenient: Offers a hassle-free way to refill your air rifle quickly and efficiently.
  2. Consistent: Provides a reliable fill, ensuring optimal pressure.
  3. Ideal for Frequent Use: Efficient and easy to use, making it a good investment for regular users.
  4. Automatic Cut-off: Many compressors have an adjustable pressure cut-off, so the compressor will automatically stop when it has reached the desired pressure. This prevents accidental over-filling.
  5. Variable Voltage: Most compressors have a variable voltage switch, allowing you to fill from your car's 12v/24v or from your home mains supply.

Cons:

  1. Expensive: Higher initial cost compared to other methods. A quality air cooled compressor will set you back at last £400-550. A water cooled system is closer to £150-£300, but  are yet to find a simple and reliable water cooled compressor, as they require an additional water source and changing of water to keep the temperature down.
  2. Maintenance Required: Needs regular upkeep to function smoothly. However, many quality air cooled compressors now have no servicing required, or very long intervals between servicing.
  3. Less Portable: Bulkier and requires a power source, making it less convenient to transport. Most 'portable' compressors come with carry handles, but are still heavier than a stirrup pump.

 

300 BAR Dive Cylinders

Pros:

  1. Quick Refills: Allows for rapid refilling, making it highly efficient.
  2. High Capacity: Stores a large amount of air, reducing the frequency of refills.
  3. Durable: Designed to withstand high pressures, ensuring long-term reliability.

Cons:

  1. Heavy and Bulky: Less convenient to transport due to size and weight.
  2. Periodic Testing: Requires regular testing and certification in the UK, adding to the hassle and expense.
  3. High Initial Cost: Similar to electric compressors, dive cylinders can be expensive to purchase initially.
  4. Overfilling: Some cylinders have a regulator fitted to slow the flow, but it is still easy to accidentally fill your gun beyond the manufacture stated limit. This can cause permanent damage to your air gun.

Conclusion

Choosing the right method to refill your air rifle depends on your specific needs. If you’re looking for a budget-friendly and portable option, a stirrup pump might be the best choice. For those who prioritize convenience and efficiency, an electric compressor could be worth the investment. Meanwhile, if you need a high-capacity and quick refill solution, a 300 BAR dive cylinder might be the way to go.

Consider your shooting habits, budget, and the level of convenience you desire when making your decision. Happy shooting!
