  • How To Maximize Air Compressor Efficiency

    The Nail Gun Network proudly presents the following guest post, originally published on "Zero Sick Days" by RolAir:

    "The key to optimal air compressor efficiency is to maintain the integrity of your entire pneumatic system. This includes the air compressor, fittings, air hose, and tools. An efficient pneumatic system will ensure that you’re getting the air you need, when you need it. An inefficient one will cost you time and money. Follow the steps below to make sure your pneumatic system keeps operating the way it was intended to.

    1. Use 3/8″ air hose whenever possible. All hoses cause some degree of frictional loss. While 1/4″ air hose is lighter and generally easier to work with, the smaller diameter restricts air flow more than a 3/8″ diameter hose would. If the CFM requirements of the tool(s) being operated is close to the air compressor’s limits, every bit of pressure counts. To ensure you’re getting the maximum amount of pressure to the tool, opt for a larger diameter hose. To get an idea of how air hose diameter affects working pressure, check out this handy Air Flow Calculator.
    2. Use shorter lengths of air hose. The idea here is similar to #1. The farther the air has to travel, the more pressure you lose. We completely understand that situations will arise when you are forced to use long runs of small diameter hose. When that happens, refer to the next step.
    3. Use an auxiliary tank. Adding an auxiliary tank in between two lengths of hose allows the user(s) to maximize distance from the compressor while minimizing frictional loss. For example, if you were to use two 3/8″ x 100′ air hoses, you’d be able to work 200′ from the compressor, but only lose pressure over the length of one 100′ section. The icing on the cake is the fact that the Air Keg can go where the compressor can’t, like on a pitched roof.
    4. Lubricate your pneumatic tools regularly. Just be careful what you put in them. The wrong type of lubricant can cause more harm than good by damaging o-rings and other internal components. The correct type of oil will be labeled as a tool lubricant and will contain special additives to promote long life for pneumatic tools. Of course, the obvious question is “How often?” That depends on the type of tool and how hard it’s being used, but for tools that get used daily, applying 4-5 drops at the start of each shift is a good rule of thumb.
    5. Check the system for leaks. This includes the entire air compressor, all fittings, air hoses and tools. Simply allow the compressor to build to top pressure with the air hose and all other tools and components hooked up. Once the compressor has stopped pumping, watch the tank pressure gauge and listen closely. If the needle stays put, you’ve got a leak-free system. If the needle starts to drop continuously (a slight drop is normal as the air cools) or you hear a hiss of air, you’ve got a leak. Excessive leaks in the system can cause your compressor to run more often than necessary, which leads to premature wear. If you have a difficult time locating the leak, we recommend spraying a soap and water solution on the hose and all fittings. A leak will cause the solution to bubble.

  • How To Avoid Destroying Your Pneumatic Nailer

    Basic maintenance on a pneumatic nailer can slash unnecessary repair costs, and will keep your air-powered nail gun running like new. But, despite minimal effort required for preventative maintenance, we continue to see far too many pneumatic tools reduced to scrap from lack of service. We've previously covered how to protect your pneumatic tools and compressor from cold temperatures - but what about year-round maintenance? Take a look at these professional maintenance tips to extend the life of most pneumatic tools, protecting your investment.

    Depending on the region, a big risk to any pneumatic tool is simply the environment it inhabits. Airborne particles can clog pneumatic nailers and cause undue wear to components within the tool. This is particularly true in coastal regions, where moisture and salt in the air increases the chance for system failure, rusting or corrosion. In areas with high moisture content in the air, it's extra important to avoid prolonged exposure to the elements. Invest in a systainer case or air-tight box to store pneumatic tools that are not in use. The same principle applies to areas that have a lot of dust or sand in the air - particularly when talking about prolonged exposure at a job site.

    A universal rule for protecting and prolonging the life of a pneumatic nailer, make sure the tool is properly lubricated at all times. A regular cause for air nailer failure is component wear due to lack of lubrication. Just like you wouldn't drive a car without oil in the engine, a pneumatic tool requires the same attention. It's also crucial to note that pneumatic nailers and staplers require special lubricant, specifically labeled as pneumatic tool oil. Many generic lubricants eat through rubber over time, which will cause more harm than help in the long run (remember most pneumatic nail guns have rubber o-rings). NEVER use WD40, motor oil, transmission fluid or aerosol lubricants.
    Unless specified otherwise by the manufacturer, make sure pneumatic nailers, staplers and other fastening tools receive regular lubrication to moving parts. Even with a self-oiling valve design, it's important to keep watch that your pneumatic nailer is receiving the proper amount of lubrication. In general, we recommend putting two or three drops of pneumatic tool oil directly into the coupling joint, before connecting the air hose. Do so daily at the start and finish of use - and be sure to fire the tool two to three times to give the oil a chance to work through the valves.
    Surprisingly enough, many other causes for system failure on a pneumatic nailer can be prevented by simply using the tool properly. Before firing the nail gun, make sure you are using the correct size and type of nail. Pay careful attention to the nail's angle, as well as the collation.
    You'll also want to check the manufacturer's recommended operating pressure, before hooking up an air compressor, to avoid misfiring caused by inadequate air flow. Too much air pressure can drive nails too deep - whereas too little pressure can cause nails to not sink evenly. Furthermore, consistently using improper air pressure can damage the pneumatic tool over time.
    Make sure you are using the proper size air compressor too. For finish and trim work, small hand-carry compressors will typically perform adequately. For framing tools, or if you are planning to connect multiple air-powered nailers, larger wheelbarrow compressors could be a better fit.

    As always, safety should be top priority. Always consult your owner's manual, or visit the manufacturer's website for detailed information about your pneumatic tool. For more maintenance advice, consult a certified repair center.

  • How A Nail Gun Works

    Ever wonder how your nail gun works? Learn the fundamentals of nailer operation, getting a behind the scenes look at the engineering marvels that power these game changing tools.

    The most common type of nail gun is pneumatic, or air-powered. Compressed air is supplied via a separate air compressor, which is powered by either electricity or gasoline. The air from the compressor is pushed through a hose into a holding area in the nail gun; this is called an air reservoir. The typical pneumatic nail gun uses a piston with a long shaft attached to it called a driver. The driver is what makes contact with the head of the nail and forces it into the work surface. The piston is located in a cylinder inside the main body of the nail gun. The air in the reservoir is held in place by a valve, which is located above the piston.

    Before the trigger is pulled, the air pressure below the piston is greater than the air pressure above it, which keeps the piston at the top of the cylinder. When the trigger of the nailer is depressed, the valve opens, forcing air into the cylinder and making the pressure above the piston greater than below it. This drives the piston down and hammers the nail. When the trigger is released, the air inside the nail gun around the cylinder is vented through the small holes drilled toward the bottom half of the cylinder. This makes the pressure below the piston greater than above it, and forces the piston back up to its starting position. Simultaneously, the valve opens back up and forces the used air through an exhaust port in the top of the nailer.
