If you are a construction professional or you just like to repair and remodel your house with your own hands, you will know that compressors are devices that are basically used to power other construction tools, thanks to their system that works by taking air and then compresses in a small space, in this case, the tank.
This compression is achieved by rapidly cooling the air with water or oil. Once compressed, the air is easier to store, as it is with divers’ tanks, or it can be directed through a tube or hose and expelled at high speed, so it can be used to paint walls or furniture.But the compressors can have multiple uses both in the professional and domestic fields. They also serve to cut some materials, drill holes, crush rock, pour concrete, and many other construction-related activities. Inside the house, the most common uses are painting, varnishing (for example after using a floor polisher) , cleaning, having car tires ready and even inflating mats and balls.
We know that you are looking for a compact air compressor and we understand that it is difficult for you to choose one due to the large number of models and brands available that is why we have prepared this guide to buy the best compact air compressoron the market today. Our main objective is that you can make a good comparison of compact air compressorthat allows you to choose a good one and at the same time economic.
Buying guide
What type of compact air compressoris better?
There is compact air compressor with very different benefits, although their principle is the same. The most important thing is that you think about your needs while discovering the following three fundamental characteristics:
Tank
Before asking how much it costs, we should think about the dimensions of the storage tank. This is very relevant when choosing ancompact air compressor, since it can determine which model is the most suitable for your needs according to the use you are going to give it.
The larger the tank, the more cubic feet of air per minute the compressor can generate. If you need it for tools, you’d better think about which of those tools have the greatest need for air and do the math from it. In this way, you ensure that the compressor has the capacity to work well with all your tools. If used only for paint or primers, there are also tankless compressors that are ideal for these tasks.
Flow
Each compressor is capable of delivering a given flow and pressure with different power. To calculate the compressed air needs, you must take into account the use you are going to give it, that is, the pressure and air consumption (liters / minute) required. In theory, it can be said that for each horse power of the compressor a flow of 100 liters of compressed air per minute is obtained.
Lubrication
Some direct applications and, above all, the use of machines previously require cleaning and drying the air using filters and decanters, since the air always has impurities and humidity. In the case of pneumatic devices, it is necessary to lubricate the air with lubricating oils indicated for generators, but there are also machines with a self-lubrication system included.
Finally, it is good to consider if we want a fixed or portable compressor. If you are moving or transporting, size and weight are important. Units with higher pressure and volume are usually larger and heavier. It is important that you have your needs clear; you don’t need to spend a lot if a small compressor meets your needs.
