How to choose the right air compressor
Once you understand a few concepts, it will be easy buying the right air compressor. This will save you time and money in the long run. With this guide, you will be able to select the right product for your needs.
Tool air consumption
For an air tool to work correctly, the compressor should supply enough air flow at the right pressure. When choosing a compressor, the air tool should be the primary concern. Each air tool has a specific air consumption measured in liters per minute or cubic feet per minute. They also operate at specific air pressures measured in bars or pounds per square inch. It is crucial that you consult the tool manufacturer or read the manual to get the requirements before buying an air compressor.
The compressor should deliver enough air pressure to meet the tool air consumption. The volume of air produced is called FAD which is also measured liters per minute. It should relate directly to a tool’s air requirements. If you intend to operate several tools simultaneously, you will have to add up their total air requirements and deliver the total airflow and pressure.
Air pressure and quality
The compressor should deliver air at the right pressure required by the tool. It should have an air pressure regulator for adjusting the pressure for each tool. Excessive pressure can damage tools built for lower air pressure. Compressed air varies in quality; the air can contain dust and oil particles unless filtered out. If your tools require clean air, consider a compressor with particle and moisture filter. The oil-less pumps negate the risk of oil entering the airflow.
The way you intend to use your tools will also determine the type of air compressor to purchase. That which is run continuously will require a greater air volume if it is to operate efficiently. You need to consider the pressure cycle, the re-pressurizing, and cooling of phases. As it produces compressed air, the compressor produces heat that can damage the machine is not properly managed. After reaching the maximum air pressure in the tank, the compressor turns off to allow cooling as the tool consumes the pressurized air. When the tool consumes the stored air too quickly, the compressor will not have adequate time to cool off and can get damaged.
For this, you should consider the duty cycle; the ratio between pressurization and cool down phase. For durable performance, the duty cycle should not be 60% of the time pressurizing, and 40% turned off. If your tool will consume a lot of air continuously, it is crucial that you consider a compressor with a higher FAD or larger storage tank.
Where you want to use the compressor
There are factors to consider based on where you want to use the compressor. Its portability comes in if you will want to use it around. It should be easily movable, and lightweight the more portable you want it. However, this comes at a cost; you will be limited in the size, power, and volume of air produced.
If you want to work outdoors where there is no electricity, then consider a petrol engine. This should never be used in an enclosed space due to the exhaust fumes. A compressor with an electric motor will be cheaper and requires less maintenance compared to a petrol engine. The electric compressor will require 10 to 15 amp electricity or even a 3 phase power supply.
The size of your compressor tank is crucial. A large one is necessary if you have high consuming tools. Larger tanks, however, make the compressor less portable d more suited for shop or home use. If your tool is used in short intermittent bursts, then a small tank will suffice.
When you purchase the right air compressor for your tools, all will be well. It is crucial that you understand your tool’s air consumption needs before choosing a model to buy. It is a long-term investment; therefore it should be done right. With air compressors, you get what you pay for, the higher the quality of construction, the higher the prices and the more durable the product.
