How To Find The Best 12v Air Compressor
Are you keen to get the most out of your car? Start by looking after your tires, so how can you ensure that they are up to the job no matter what the conditions? Keeping tyre pressures on the mark is no longer down to when you next fill up and hoping for the best mid tank. Improved 12v air compressor technology now means small, lightweight machines can be found for a very reasonable layout.
Combine one with the battery (yep – your car’s got one of those) and you can get compressed air on demand. The only issue is that there are a number of models that you can choose from and each comes with its own selection of pros and cons so here is some collected wisdom about the best 12v air compressors in the market place.
What Should I Use My 12Volt Compressor For?
When it comes to cars, tires are quite the Thing. The Thing is, they will often deflate of their own accord albeit slowly and imperceptibly and sometimes you may even need to deflate them yourself.
Owning your own 12v air compressor is probably the best investment you can make in maintenance for your car. Keeping an eye on tyre pressure means tyres will last longer and you can improve
- Vehicle Handling
- Fuel consumption
If you are fan of the great outdoors there is also an extra benefit to owning a 12v compressor. When you switch to off-road in your SUV or 4x4, no matter how good the four wheel drive is, you still need maximum grip, especially on looser surfaces. The best solution is to deflate your tyres so that you get greater surface in contact with your tyre. No worries there, that’s pretty straight forward, just let the excess air out. However, when you return to the tarmac, you need to inflate your tyres to the correct on-road pressures. Cue the 12 volt compressor (well, cue the BEST 12 volt air compressors actually)
Benefits of Small Lubricated Air Compressor
When we’re talking about lubricated compressors we mean they need oil to lubricate the engine and help it run. Oils main purpose is to lubricate all the parts of the engine which help stop wearing out of all the mechanical parts.
If you want a quieter compressor then you might want to look the models that take oil. Oil lubricated compressors are known to make less noise. The cast iron models will also out last compressor designs that don’t need oil. If you’re going to do quite a lot of work with your air compressor and need it for more than just the basic DIY small jobs a cast iron model that needs oil to lubricate the engine may be your best bet.
Oil also helps keeps the engine cleaner and can aid in the temperature control of the parts getting too hot (you don’t want your engine to overheat because it can cause damage to the engine).
When rust and rubbing of the engines parts begin to occur this further causes wear and tear commonly known as corrosion. Again the way to prevent corrosion in compressor engines to make sure the correct engine oils is being used and that right amount of oil is being used. Levels of oil should not be too low or even too high or that matter.
