The HK Army Airbase 4500psi Portable Air Compressor lets you fill your own HPA tanks wherever you are. Set the pressure, hook up your tank, and the Airbase fills it and shuts itself off when it hits your number. No more driving to the field or a shop just to top off a tank, and no more ending your day early because the fill station is down.
Fill Air Tanks at Home, at the Field or From Your Truck
The Airbase runs on standard 110V wall power, or you can clip it right onto a 12V car battery with the included cable. That makes it just as handy in your garage the night before as it is in a parking lot with no air on site. At about 22 lbs with a carry handle on top, it's easy to throw in the back seat and bring along.
Who It's For
- Players who are tired of paying for fills or waiting in line at the station
- Groups that play where there's no fill station
- PCP airgun owners who need to refill cylinders between sessions
- Anyone who wants a backup air source for long weekends away from a fill station
Smart Auto Shutoff and Digital LCD
The front panel has a large backlit LCD that shows your live pressure, motor current and temperature while it runs. Use the arrow buttons to dial in your target pressure, up to 4500 psi (300 bar), and the Airbase stops on its own once it gets there. That means no babysitting a gauge and no guessing.
Simple Three Step Startup
The startup sequence is printed right on the panel: power on, fan on, then motor on. It's easy to follow even if this is your first compressor.
Built to Keep Air Clean and Temperatures Down
High pressure compressors make heat and moisture, so HK Army built the Airbase to handle both.
Integrated Cooling Fan
A built in fan pulls heat away from the pump while it runs, and the display tracks temperature so you can see what's going on.
Filtration and Moisture Control
The inline filter on the fill hose uses replaceable cotton filter cores, and extras come in the box. A water drain valve on the back lets you purge moisture, and an air release valve on the front bleeds off pressure after a fill.
Easy Maintenance
The Airbase has an oil fill port on the side, so check the oil level as shown in the HK Army manual. A spare parts kit with O-rings and fittings is included to keep it running.

Airbase Fill Times
Here's how long HK Army says the Airbase takes to fill a tank from empty. Topping off a tank that still has air in it goes a lot faster.
| Tank Size | Target Pressure | Fill Time | Fill Rate |
|---|---|---|---|
| 15ci carbon fiber | 4500 psi | About 8 min | 1.88 ci/min |
| 48ci aluminum | 3000 psi | About 15 min | 3.20 ci/min |
| 68ci carbon fiber | 4500 psi | About 34 min | 2.00 ci/min |
Actual times depend on the room temperature, how much air is already in the tank and how long the compressor has been running.

Frequently Asked Questions
Yes. Set the shutoff to match your tank's rating, 3000 psi for most aluminum tanks or 4500 psi for carbon fiber, and the Airbase stops there automatically.
From empty, HK Army rates it at about 8 minutes for a 15ci 4500 psi tank, 15 minutes for a 48ci 3000 psi aluminum tank and 34 minutes for a 68ci 4500 psi tank. Top offs are much quicker.

Yes. HK Army designed it for both paintball HPA tanks and PCP airgun cylinders. Just set the pressure to match your cylinder's rating.
The fill hose has an inline cotton filter, and the water drain valve on the back lets you purge moisture from the compressor. Replace the filter cores as needed. Spares come in the box.
HK Army says it runs quieter than many traditional high pressure compressors. Like any compressor it still makes noise, so a garage or outdoor spot is a good place to run it.
