Best Air Compressor for DIY Mechanic Buying Guide

Buying the best air compressor for DIY mechanic requires careful reflection. An ideal compressor needs focusing on many performance factors. A purchase guide for the air compressor is the starting point before making this decision.

The buyer’s guide below discusses the factors to consider before making your final decision.

Pressure capacity

For the target flow to be reached, enough pressure is required. The air pressure is typically given in pounds per square inch. This changes depending on the size, brand, and design of the compressor.

If this is necessary for heavier applications, the pressure must be more significant. With the increase in air pressure, even the flow rate or the flow rate also increases.


The nominal power of a compressor must be taken into account, as are the other factors. A variety of air compressors for DIY mechanic can have ratings ranging from 1.6 to 6 horsepower.

However, this factor is typically governed by pressure and pressure S.C.F.M. of the compressor. Power must not be an independent factor. You must comply with the requirements of its use.

Power supply

Your energy source is essential because it determines the size of the compressor you can use. If the power source is constant, a single-stage reciprocating air compressor can be a great option.

But if you’re in an area cut continuously by power cuts, production stops, and power outages, the tank type is your best option. You can use it when there is power and use it when you need it. It will maintain the necessary pressure for long hours depending on its use.

Available space

Before installing your compressor, you need to have enough space to do so. That means that if you have enough space, a larger compressor would be ideal. But if there is no room for a larger compressor, buy a laptop.

However, space considerations should only be considered once you are satisfied with the performance. In some cases, you may even need to create space.

Frequently Asked Questions (FAQs)

What is an aftercooler and what does it do?

An aftercooler is a piece of equipment which uses air flow to cool an air compressor by discharging air temperature before storage. The cooling function dries out moisture from the compressed air.

The most significant way to do so is by installing a moisture separator inside the piping after the aftercooler for it to collect and drain all the moisture before it gets into the tank.

What are splash lubrication and its benefits?

Splash lubrication is an engineered design method of lubricating the cylinder moving parts and the crankcase using dippers which make contact with an oil surface when the air compressor is still running.

The device dippers are mounted to the bottom of the joining rod and contoured to create typical splash patterns for great lubrication. The whole process reduces wear and tear of the moving parts while ensuring the best performance.

In conclusion, your compressor must match the use for which you buy it for, in this case for a DIY mechanic. Therefore, the best air compressor for DIY mechanic you need should answer your performance questions.

With the above review and buyer’s guide, you will have the opportunity to buy the best equipment to work for many years.
