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.\u003c\/p\u003e\n\u003ch2\u003eFill Air Tanks at Home, at the Field or From Your Truck\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eWho It's For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlayers who are tired of paying for fills or waiting in line at the station\u003c\/li\u003e\n\u003cli\u003eGroups that play where there's no fill station\u003c\/li\u003e\n\u003cli\u003ePCP airgun owners who need to refill cylinders between sessions\u003c\/li\u003e\n\u003cli\u003eAnyone who wants a backup air source for long weekends away from a fill station\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSmart Auto Shutoff and Digital LCD\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eSimple Three Step Startup\u003c\/h3\u003e\n\u003cp\u003eThe startup sequence is printed right on the panel: power on, fan on, then motor on.
