Savvy manufacturers never stop researching ways to reduce costs and improve productivity… As the at the start tariff of electric power tools is without question attractive, pneumatic tools give you a lower total cost of ownership and greater throughput over the long term.

Industrial air grinders provide a different value proposition than electric grinders. These are engineered for longevity, efficiency, and most importantly safety. Air powered grinders are increasing in popularity because of the benefits provided regarding their cost. Adopting air powered grinders results in greater cost savings through the entire lifetime of the tool.

In the following paragraphs, we explore 5 clear cut benefits afforded by way of industrial grade pneumatic grinders.

1. No Risk of electrical Shock
Grinders of most varieties are frequently used in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a threat to operator safety due to electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, like acetone, to completely clean and prep metals ahead of welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when working in confined spaces such as those based in the mining and tank cleaning industries. As opposed, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore produce a safer work place which cuts down on probability of generating OSHA violations. To put it simply, air tools are safer than electric tools because an aura hose won’t emit a spark and is found in wet conditions.

2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders provide a better capacity to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower in a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the potency of their tools through the wattage fed inside their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications is that the power fed to the motor isn’t the same wattage that arrives to the spindle of the tool. The truth is, only 50% to 60% of the rated wattage actually involves the abrasive or accessory. On the other hand, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will provide that very same level of power to the tool.

3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is a priority for your operation (and when isn’t it?), pneumatic grinders will help you meet your purpose. When working with grinders of all sorts, Revolutions Each minute (RPM) play a crucial role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to perform optimally at a specific RPM. Fortunately, modern pneumatic grinders come with a speed control mechanism, (also called a governor), that ensures proper RPM by money air flow to the tool. As the operator places downward pressure around the abrasive, the governor “opens up”, increasing venting for the motor and ensuring the best spindle speed.

4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a product or service Manager for Diy equipment at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them within a hot sun doesn’t help either.” By their very nature electric motors possess a rated duty cycle which must be respected. Without a periodic rest, the warmth generated through the motor itself will diminish performance and in the end cause premature tool failure. In reality, for every single 4 minutes running, an electric grinder was designed to have one minute rest.

Furthermore, the generation of particles is inherent in any material removal process. With all the open grate style motor compartments required for cooling, electric tool motors tend to be more prone to the accumulation of the dust and dirt. As opposed, Industrial Grade Air Tools are designed especially for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning they’re meant to run Round the clock Seven days a week (when used in combination with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not Fibreglass driving them to more up against the impact from repeated drops. Pneumatic grinders can even be used underwater in the event the exhaust is vented higher than the surface!

5. Simplicity of Servicing and Sustainability
An advertisement grade grinder is not a disposable piece of equipment and immediately find themselves in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders may be updated and stay periodically rebuilt often over. The common electric tool maintenance interval is between 60 and 120 hours and the tool will typically need, at a minimum, a new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very industrial grade air grinder can run up to 2000 hours between tune-ups. When the time comes to service your air tools, convenient and clearly labeled kits can be found which contain the most frequent wear parts.
