With many air pumps for airguns now available, it’s strange to think that FX Sweden was the company that introduced us to the benefits of this simple, manually-operated system over the cumbersome diver’s bottle. Since the mid-90s they’ve developed the original concept considerably. I say this, as when it was first produced the effort needed to fill a rifle was not that tempting to those who were used to the convenience of a diver’s bottle. There are now many very efficient pumps to choose from, so the effort needed is a fraction of what it once was. FX have two on offer - the Three Stage and the Four Stage Turbo.
Some Assembly Required
The Three Stage is relatively light and stands 24.5” high, as with most pumps some basic assembly is required. This entails screwing on the base/foot plate, external moisture trap and screwing in the micro-bore filling hose. Uniquely the external moisture trap has a complimentary internal one which doubly ensures no moisture enters the PCP’s air reservoir. The T-bar handles are over 8” wide with chunky rubber grips for a secure hold and the design is simple to use and does exactly what it claims.
The flagship model Four-Stage Turbo Pump stands slightly higher at 25.25” and there’s little difference between them in operation until you get to the top of a fill charge. Here the Turbo makes pushing in those last few CCs of compressed air far less strenuous due to some clever internal engineering. It actually uses a different and unique gearing system so you can switch between achieving high volume with low pressure and vice versa.
Now I’m no expert in pneumatics, but theoretically the gearing system on the Turbo model should make pumping to high pressure faster and easier. The method to achieve this is that you pump in the first three quarters of a fill using 300cc of air per stroke which you choose by closing the top valve (the serrated edged brass dial found in the middle of the pump’s handles.) This automatically drops down a gear and fills with 200cc of air per stroke for the final part of the fill - which of course would usually be the most tiring part of the filling process. It actually works well but although less strenuous the filling obviously takes a little longer.
Both pumps come with a 5-year warranty and their robust rugged build is certainly impressive. These pumps are up there with the best of them, quality engineered tools that do the job efficiently and cost effectively. So if you have a PCP but feel that you’d rather do away with relying on a divers bottle, give these pumps a look.
