How to Choose the Right Air Compressor

Tools run on an air compressor home repairs, and hobbies can make quickly and effortlessly. Professionals who use air compressors rely on their effectiveness to save time and effort. Air-powered tools are environmentally sensitive and flexible. With the wide variety of air compressors on the market, it makes sense to do your research and know what to look for to choose the right compressor. If you want it to be lightweight, you may want the best small air compressor


• Check the required ratings on your tools before beginning the search for a new air compressor. Most devices require one pound per square inch or PSI score of at least 90. More PSI is better if you plan to add more devices to your inventory that may require higher ratings.

• Look for air compressors 3-4 cubic feet per minute to (CFM) by 90 PSI. The CFM measures the amount of air which is in motion by the compressor and is usually associated with the PSI to provide the rating. Look for a higher CFM rating if you intend to have more than one instrument at a time running the compressor.

• Consider the horsepower (HP) of the machine. Horsepower is assessed at two levels – the amount of power that is used to start the engine and while running amount used. Find adjust the running strength ratings on the compressor with the power needs of your tools. A score of 5 HP running is usually sufficient for home use.

• Find an air compressor with a smaller tank and a larger engine when you run your tool continuously. The larger tanks that hold more than 30 liters of air time are best used for intermittent power tools, while smaller tanks 20-22 gallon best with larger engines.

• Decide how you will use the air compressor. Smaller compressors can be easily moved around a home or workplace, while larger units are more stable and require a firm mounting area.

• Know where the compressor will be used when choosing between electric and gas-powered machines. An outlet is required to run an electric model, but it is cleaner, while a gas-powered device more portable, yet releases vapors which are not appropriate to be in closed spaces.


  • Look for an air compressor from a reliable manufacturer which has been in business for a while. Check reviews in Consumer Reports or other sites such as Air Compressor Resource.
  • Cheap air compressors are widely available, but they are not always the best bargain. Cheaper air compressors are designed for single use and replaced after approximately 100 hours of use.

How to repair a leak in an Air Compressor Tank

If your air compressor keeps the sufficient pressure, check your compressor for a leak. Leaks are the source of wasted energy, spending 20 to 30 percent of the compressor output. A small leak in your air compressor tank can destroy the entire machine. Leaks reduce the pressure of your system, making the air fewer resources to work efficiently. The main areas where leaks can develop in your tank include compressor hose joints and a shut-off valve.


• Make sure all the devices of the air from your air compressor tank with an ultrasonic acoustic detector. Bringing the ultrasonic sensor near the joints and your Connections air compressor tank. Press the start button on the sensor. The sensor detects the high-frequency hissing sound which is coupled to the air leak and will show a red light for a leak.

• The leaky hose joints with pliers. Then reassess the compressor control system for leaks with the ultrasonic acoustic detector. If a red light is still displayed, replace the hose of your compressor tank.

• Cut the tube section just above the old assembly. Insert a new compression ring fitting just above the hose. Pressure on the compression rings with the forceps.

• Fit a wrench on the nut of the pressure valve. Turning your wrench clockwise to release pressure of the valve.

• Wrap Teflon tape around the threads of a new valve assembly. Fit a key to the usefulness of a new Compression fitting to the ring. Turning to tighten the nut wrench counterclockwise.

• Apply the ultrasonic acoustic detector in the vicinity of the replacement assembly. Press the start button. If a red light is still displayed, is replaced by the assembly again in the same way as before.
