Pneumatic versus Hydraulic

Pneumatic versus Hydraulic

If you are in the market for a high-capacity torque wrench, one of the most important aspects you need to consider is whether you reach for the Pneumatic or Hydraulic power tool. Both have their pros, and both certainly have their cons; therefor, it’s essential to have a comprehensive understanding of both before you spend your hard-earned cash. Like most things in life, the question of which is better ultimately comes down to the use-case scenario.

Entry:

While both tools require a basic understanding to operate, Pneumatic wrenches are typically much easier to use. Firstly, the Pneumatic wrench can be efficiently used by one person, unlike its hydraulic counterpart, which sometimes requires two people to operate safely. This need for only one person is because pneumatic wrenches are powered by a general-use airline, meaning there is no need for specialised equipment, resources, or maintenance regarding oil management. On the other hand, the Hydraulic wrench uses a specialised oil that can become a real headache when misused.

Winner: Pneumatic

Safety:

When purchasing a high-powered torque wrench, safety should be of primary concern, and while both Pneumatic and Hydraulic tools have their risks, they differ in what to watch out for regarding safety precautions. Both tools provide general risks through pinch points close to your hands and chords that pose a tripping hazard. However, due to the large size and previously mentioned complexity of the Hydraulic Wrench, it is much more dangerous due to its dependence on electricity and hydraulic fluid, which poses a severe fire risk when mismanaged.

Winner: Pneumatic

Output:

Now it’s time for what we have been all waiting for; the power, or output, of both machines. Both tools have their use here; however, if you use them for high-capacity torque application, you would be remiss in reaching for the pneumatic wrench as the hydraulic variation is up to six times more powerful. Due to its large size and fasteners, a hydraulic wrench can reach a maximum torque capacity of up to thirty-five thousand pounds.

Winner: Hydraulic

So, who wins the battle betweeen Pneumatic versus Hydraulic? The answer is; it depends. If you want a general-use tool that does everything well and doesn’t pose any serious risk to you or your employees, the Pneumatic wrench is the one for you. However, suppose you need the capabilities of a high-capacity torque wrench and have an advanced understanding of health and safety. In that case, the hydraulic wrench will provide you with the most satisfaction. At the end of the day, the real winner is the consumer, as we are lucky enough to have the option of choosing which tool is best.

Winner: Consumer
