Positive Displacement Air Compressor
Positive-displacement compressors work by increasing the pressure by reducing the vacuum that holds the pressure using a reciprocating piston.
This type of compressor typically has a crankshaft, a piston, connecting rod, cylinder, and a valve head. These parts are powered by an electric motor to create an internal combustion. As the piston strokes, a vacuum is created on one side while the full side sends the air into the holding air tank. At the very top of the cylinder is the discharge valve.
Negative Displacement Air Compressor
This type of compressor works by drawing and capturing air in a closed chamber. This process is then followed by reducing the chamber volume to compress the air.
Depending on the pressure you are are looking, car air compressors can further be categorized into three:
- Low-pressure air compressor: typically discharges a maximum of 150 psi.
- Medium pressure air compressor: can deliver anything between 151 and 1000 psi.
- High pressure air pressure: can deliver over 1000 psi.
Irrespective of the psi output, most modern air compressors utilize the 12v supply through the battery terminals or the cigarette lighter. However, there are are other models that still require power inverters.
Factors To Consider Before Buying Car Tires Air Compressors
Right off the bat, you dont want to be stranded in the middle of nowhere with an air compressor louder than Boeing 747 engine. It’s utterly annoying! With that said, all the air compressors irrespective of the brand will produce some certain level of noise. So it’s up to you to decide the decibels you are comfortable with.
The second and most important factor to consider while buying an air compressor is compatibility. You don’t want to buy a fancy equipment just to occupy your trunk space without helping you. For this reason, ensure that the compressor can inflate the tires you have as some are capable while others aren’t.
Although you may love a particular brand, you don’t have to settle for their air compressor if it’s not portable. Always look for a small unit that will comfortably fit in your trunk. After all, the only point of having an air compressor is for you to use in emergency cases. Needless to say, small compressors are practical and don’t cost a fortune.
It’s always nice to have an intuitive unit that seemingly predicts what you need. For this reason, always settle for an air compressor that has some few pre-programmed settings like the PSI settings, ON/OFF to overcome all the little inconveniences.
Last but certainly not the least is the budget. It’s important to note that there are multiple air compressors on the market that come with minor differentiating tweaks. A minor tweak on an air compressor can be worth a few hundred dollars. However, the bottom line is that a good unit should help you do one thing–inflate your tires.
There is no need of spending an extra 500 buck for some minor caduceus you can do without like the color of your unit.
