My Thoughts on Portable Compressors

Portable PCP compressors can improve the way airgun shooters manage their equipment, depending on their needs. I personally like using a CF tank, and especially since I have a commercial-grade Omega Compressor to keep them filled, it is the most effective approach for me. However, there have been times in my airgunning history when I did not have a compressor, and there wasn’t a local paintball or dive shop for me to use. I had to drive 45 minutes cross-town for a refill, which, with the volume of shooting I do, was a real inconvenience. However, if you have a nearby place to charge your tank(s), only do a moderate amount of shooting, and don’t want to invest in a full-size compressor, a good CF tank is a great option. If you do a great deal of shooting and can afford it, having your own high-capacity compressor and a couple of CF tanks is one of the best solutions. But if your shooting volume is high, you don’t have a nearby place to fill tanks, or you’re looking for a solution that provides independence at an affordable price point, a compact compressor can be a good solution.

But even in my situation, owning a full-sized compressor and several CF tanks, I still have a strong use case for a portable compressor. I’ll give you a quick overview of why I included a portable compressor in my toolbox for keeping PCP rifles charged and ready to hunt. A major factor that resonates with many shooters is that these compressors offer independence from paintball or dive shops and provide complete autonomy, but for me, the most valuable aspect is that on multiday hunts, I have unlimited air and the ability to charge to high pressure. When heading out on a 10-day trip to South Texas, for instance, I don’t have room to carry more than a couple fully charged CF tanks, which limits the number of full-pressure recharges. In this case, as the pressures drop on my primary tanks, I can use the compact compressor to top off the guns. This is especially useful for those rifles operating at very high fill pressures. Most portable compressors run on both AC and DC power, meaning you can plug them into a wall outlet or connect them to a vehicle battery while in the field.

You might say, “Just use a hand pump” as a much less expensive way to achieve this result. Hand pumps are inexpensive, but they’re also exhausting, especially for rifles with large reservoirs, operating at high pressure, or when using multiple guns. In the past, I would pack a hand pump when hunting out of state, as traveling with a CF tank presents several logistical problems. But having spent many hours in the hot and dusty outback filling a rifle with a handpump, I can tell you….. you don’t want to do that!

A portable compressor eliminates physical strain and long pumping sessions, providing a consistent, controlled fill with minimal effort. PCP rifles perform best when filled to precise pressures, and many modern rifles today operate at higher pressures ( in excess of 4000 psi), so a CF tank that fills to 4500 psi is limited on the number of full-pressure refills it can provide. Portable compressors allow you to set automatic shutoff points, fill the gun slowly and consistently, and top off refills once your external CF tank pressures start to fall off. This allows you to use all the air in the external tank, by supplementing the charge with the portable compressor. I find that topping off the gun, combining the external tank and portable compressor, allows for a fairly quick refill to the optimal operating pressure.

This is not just a hypothetical “what if?” scenario; I have literally saved several hunts and range sessions over the last few years using a compact compressor. These days, I always pack one when heading out for either a range session or a hunting trip. Even if I don’t end up using it, it’s a great insurance policy. To wrap it up, if you don’t have a place to conveniently refill tanks or want a cost-effective solution for feeding your air rifle, a portable compressor is a viable option. If you have a CF tank and a convenient place to refill it, but are using a gun that fills to high pressure, a portable compressor can be an effective way of topping off the charge. And if like me, you shoot a lot with guns that charge to high pressure, and travel to remote areas to hunt with them, a portable compressor is both a great way to top off guns as well as an insurance policy to make sure you are never stranded without air.
