How To Choose the Best 20-gallon Air Compressor? Buying Guide
Buying the best 20-gallon air compressor is an important and tricky task. However, with the right knowledge and guidance, you can easily select the perfect air compressor that aligns with your needs. So, to make your task simple and easy, we have prepared a buying guide after much research. Let’s have a look at some important factors to consider when buying a 20-gallon air compressor:
Pressure
Pressure is one of the important factors to keep in view when choosing the best 20-gallon air compressor. Most of the 20-gallon air compressors have a pressure range between 150 Psi. However, some may have less air pressure, and others have more than this. The selection of a specific air compressor depends on your job. There is less pressure or PSI for small tasks, while more PSI is required for heavy tasks.
CFM Rating
The CFM rating of any air compressor indicates its performance and motor power. For heavy tasks, you should opt for a high CFM air compressor. It will increase the productivity and efficiency of your operations. While for small and DIY tasks, you can select the less CFM ratings.
Noise Level
Due to the big tank size, some 20-gallon air compressors are very noisy. But some brands manufacture air compressors with quiet labels for people who dislike working in noisy environments.
If you are also one of those who want to work in a calm and peaceful environment, make sure to check the noise level when buying your air compressor. If you need a 20-gallon air compressor to work in public areas and indoors, you must opt for quiet air compressors.
Duty Cycle
For efficient performance and extended operating hours, you must consider the duty cycle. Some 20-gallon air compressors have less duty cycles for better performance and long operating hours. So, the selection of the duty cycle also depends on your task and needs.
Maintenance Requirements
Some 20-gallon air compressors are lubricant, and others require regular oil changes and maintenance. If you need an air compressor with less maintenance requirements, select an air compressor with an oil-free pump. With these air compressors, you don’t need to spend extra money and effort on oil changes.
Tank Style
Tank style also matters when selecting the best air compressors. The 20-gallon air compressors have two types of tank styles: one is horizontal, and the other is vertical. If you have sufficient storage space, you can opt for any tank style. However, if you have less storage space, you should select a 20-gallon air compressor with vertical tank style. It is easy to store even in a little area.
Portability and Weight
Another important factor to consider when buying a 20-gallon air compressor is portability. Portability matters if you need an air compressor to carry it from one job station to another. Some 20-gallon air compressors are very heavy and difficult to carry. At the same time, some are specially designed to be lightweight and highly portable. They also feature a handle and tires to enhance their portability.
Price
When buying a 20-gallon air compressor, make sure to check the price tag. The price of these air compressors depends on the model, features, and brand. However, some are more expensive while offering less performance and durability than some less expensive models.
So, checking the price tag and comparing it to other models is important. However, try not to compromise on the quality and performance.
Brand and Reviews
The brand reputation and customer reviews also matter when choosing the best 20-gallon air compressors. Always select a well-reputed and reliable brand. Moreover, read the customer reviews to make an informed decision.
