And use an air gun to blow away dust and dirt, especially from around the gauges, couplers, and pump motor. So regularly check the compressor for loose parts and screws, and tighten any that you find. Plus, they’re often operating in dusty environments. However, compressors vibrate quite a bit, which causes parts to loosen up over time. Most have permanently sealed, oil-free motors, so there’s no need to check, fill, or change the oil. Air compressors are relatively maintenance-free.For example, my 18-gauge brad nailer has a recommended operating range between 70 and 120 psi I typically adjust the compressor to about 95 psi, which is mid-range. If the compressor delivers too little air pressure, the tool won’t work properly, whereas too much pressure can damage the tool. For maximum efficiency, adjust the compressor’s air pressure to match the recommended psi rating of the air tool you’re using.Never use an extension cord longer than 50 feet with an air compressor-the voltage drop will be too great. However, if you must use an extension cord, use a 12-gauge cord that’s less than 25 feet long, or a 10-gauge cord that’s no longer than 50 feet long. Using an extension cord can result in a drop in voltage, which could prevent the compressor from starting. Whenever possible, plug the compressor directly into an electrical outlet.The cushioning will absorb sound, protect the floor, and dampen vibrations. During use, set the compressor on a folded, quilted moving pad.Failure to do so can eventually lead to corrosion and tank failure. After every use, open up the drain valve at the bottom of the tank to expel any condensation.Here are five simple ways to get the most out of your air compressor: And I have an air gun/inflator kit that’s super handy for blowing dust off surfaces and for inflating anything: car tires, rafts, air mattresses, pool inflatables, and more. My pneumatic collection also includes an impact wrench, ratchet wrench, cut-off tool, and random-orbit sander, which are useful when working on vehicles. That has involved using a finish nailer to install baseboard molding, chair rail, and window and door casings a brad nailer to assemble cabinets, drawers, and bookcases a pin nailer to attach thin moldings and hardwood edge banding and a narrow-crown pneumatic stapler for upholstery work and attaching plywood cabinet backs. Over the years, I’ve most often used my compact compressor to drive fasteners. Once you own a portable air compressor-and start collecting pneumatic tools-you’ll wonder how you ever got along without an air-powered arsenal. However, compressors with smaller tanks are quieter, lighter, and easier to carry around. And larger compressors often have two universal couplers, so you can run two air tools simultaneously. Portable models with larger tanks hold more air, so they don’t cycle on and off as often and have greater maximum psi ratings to handle larger pneumatic tools like framing nailers and paint sprayers. That’s still plenty of power to run most air tools. Compact compressors move less air than much larger units, typically producing between 1.0 and 2.8 cfm. This number is expressed in cubic feet per minute (cfm) or standard cubic feet per minute (scfm). As you use an air tool, pressure inside the tank drops, and the motor kicks back on to re-pressurize the tank to the desired psi.Ĭompressors are rated by the volume of air delivered at 90 psi. The pump motor then shuts off, and the compressor is fully charged and ready to work. The pump forces air into the tank until it reaches the desired pressure as measured in psi. Portable air compressors, like their larger predecessors, are relatively simple machines comprised of two main components: an electric pump and an air-storage tank.
