Users are split on the advantages of air vs. electric tools. There are things to recommend about both, and situations where one or the other is useful.
Here are some of the advantages that pneumatic tools have over electric ones.
First off, be mindful of moisture and dust. Long power cords are a hazard, especially in industrial settings where they could get crushed or cut inadvertently. Short-circuits and electrocution are a common cause of injury when working with tools; by using pneumatic tools, you will avoid the risk, since a punctured air line can do far less damage, at least at a typical 100-130 psi. Same goes for working in wet environments – if there’s moisture in your work area, you don’t have to worry about getting water in the works and shorting out your pneumatic tool.
Next, the issue of dust works against electric tools as well. Since electric motors have cooling vents, they can ingest dust or shavings. If you’re sanding or grinding conductive materials such as metals or carbon, the dust can get into the motor and cause a short.
Air tools have another advantage – they require less cooling. This is partly due to the fact that they don’t have a motor built in, and partly because the rapid expansion of compressed air as it escapes the tool after being used for motion causes it to cool, keeping the tool temperature down as well.
Due to the fact that they don’t contain a motor, air tools deliver way more power per pound. This makes them especially desirable in applications that require lots of power in a portable package. For a tool like an impact driver, air is practically a must – no electric devices come close to packing the same punch.
These are only some of the reasons to pick an air tool over an electric one. In our next blog post, we will list some of the ways that electric tools are preferable to pneumatics.
