In the grand scheme of things, air powered tools are a relatively new addition to the tool industry. They are not only really useful and pretty cheap to run but can maximise the amount of work you get done whilst minimising the effort. To run your air powered tools you need an air compressor and a gas air compressor is hard to beat.
There is no standard gas air compressor as they come in a variety of sizes and volumes. The larger ones are usually on wheels and have handles so you can move them around easily. Gas compressors come with different horsepower and as well as pounds per square inch or ‘PSI’ ratings. Many people find that gas powered compressors are much more useful than electric powered ones as you do not need to be near an electricity outlet to get it started.
The first thing to consider when buying a gas air compressor is what type of jobs you will be using it for. If you need it for jobs such as airbrushing you will not need a compressor with a huge volume capacity; one with a 30 PSI rating and volume of around 5 litres should be ample. Buying one bigger than you need may result in lots of time wasted waiting for the tank to fill; time that could be spent on the job.
If you need your compressor for out of the way jobs, such as fixing the roof, a portable compressor would be your best bet. However, they are not always that powerful so for other tasks, such as pumping up your tyres, you may need a compressor with a larger capacity. Another thing to think about before purchasing a compressor is power source. High capacity compressors run on up 240 volts whereas smaller ones can run on a little as 11 volts. Again, this is something you need to check out first.
Last, but not least, you need to think about budget. Gas air compressors can range dramatically in price. Large, powerful compressors can run into four figures but smaller, more basic ones are only a couple of hundred dollars.
