What To Look At When Shopping For Cheap Air Compressors
A cheap air compressor is an essential tool to own for work or home use. It can help you do jobs faster and easier. Buying a cheap compressor is not easy. There are many factors to consider before purchasing one to make sure you get the best deal for your money. Here are some factors to consider before buying a cheap air compressor.
The first thing you will need to look at is the speed of the motor. A large slow motor will only be good for jobs that don't require high speed, such as household maintenance. A medium-speed motor will be good for those types of jobs where you need a strong, durable motor and portability. A cheap air compressor with a slow motor can be great if you plan to store it in a large storage area and only use it occasionally when needed. If you want to use the machine regularly, a large slow motor is probably better.
Next you will need to look at the PSI and the flow of air. A lower PSI will produce less compressed air, while a higher psi will produce more compressed air. You can usually get a pretty good idea of the PSI by reading the on-screen specs. Be careful though, some brands may advertise 'higher' PSI but have lower capacities!
After you have determined the motor size and the PSI, you should also consider the power source. If the motor is DC-powered, the power source must be AC. Otherwise, the machine will not work! Also, some air compressors come with a cord, and others come with an external power source. A portable motor is best if you use the machine outside or in an area that does not have an electrical power source.
Another important feature is the portability of the portable air compressor. Some are easy to carry, but many have to be put together. Look at how easy the assembly is to put together before making your decision. If the assembly is not too difficult, most portable compressors will have step-by-step assembly instructions with them. Look for this feature when you are looking for your new portable compressed air compressor.
A few other features to look for are the number of air hoses, the size of the air compressor hose, and the valve type. Most portable compressors have one large valve for normal (large hoses) and variable valve lengths (many different hoses). Be sure to get the correct size air hose for your model of air compressors before you buy one!
The last thing to look for when shopping for cheap compressed air tools is the PSI and the RPM. The PSI is the pressure of the compressed gas in pounds per square inch. The RPM is the speed at which the tool works, usually measured in revolutions per minute. Look at these numbers to determine what the appropriate PSI and RPM are for the intended use of the air compressor.
The last thing to consider is the oil-free pump. Oil-free pumps mean no oil leaking from the motor, and there is no need for lubrication. Check the pump's compatibility with your motor, as well as the fit of the motor to the air compressor. A lightweight air compressor does not need the motor to be extremely powerful to work; just fit the proper motor, including all the moving parts, so that you can get the job done with as little energy use as possible.
