We are often asked the question, "Should I use an air tool or a power tool?" Many users feel that one category is enough for everyone and every application. NOT really!
The answer to this question basically depends on the application and what you are trying to achieve. Only with a good understanding of the requirements of the tool, as well as the knowledge of the different technologies used to power the tool can you make an reasonable decision on “go with pneumatic or power tools?”Each one has its pros and cons. So, before you decide which one to use, first consider:
1. What do you want from the tool? For example, its power, efficiency, ergonomics or ease of movement.
2. What is your work environment like? For example, can you guarantee the gas supply system to work well? Or, power outlets are all that you have? Will you be working in an environment with specific requirements.
Once you know exactly what you're looking for, you can start looking at the merits of each technology and see which one meet your needs in particular. The following are the main advantages of each technology:
Convenient: Electricity is readily available in most workplaces, so plug your tool into an outlet and get to work quickly.
Purchasing: These tools are easy to purchase as many vendors sell them. No need to go to a professional supplier to buy.
Cost: Generally speaking, the cost of power tools is relatively low.
Mobility: Unrestricted by power source (as long as the battery is charged) - you can use the tool in more situations as you want. With no cables, these tools offer excellent mobility and flexibility. You can easily use these tools in tight and hard-to-access spaces.
Autonomy: For everyday applications and moderate use, cordless tools have good autonomy, as today's batteries last for a long time per charge. The user does not need to interrupt work to change the battery. Battery technology is also constantly improving.
Ergonomic Features: These tools are lighter, more powerful and have a more ergonomic design than power tools.
Cost: They are less expensive to maintain
Productivity: Air tools can last for a long time if they are well maintained and lubricated
Let's take how to choose a grinding machine as an example to understand further. Grinding machines are common in many industries. Electric (plug-in) angle grinder, cordless angle grinder and air-driven angle grinder are all popular and widely used. So, first, ask yourself "What are the key features of the tool that are important to me?"
If performance is critical to your application, an air powered grinder is even better. They have a higher power-to-weight ratio and longer service intervals for better overall performance.
However, if you are very concerned about the initial purchase cost, electric grinder may be a better choice as they are very attractively priced.
Also, if you don't have compressed air readily or any electricity outlets available at the job site, or the portability is the most significant feature in your case, then undoubtedly, cordless grinder will be a more practical choice.
