Five Aspects Of Using Air Powered Grinders Instead Of Electric

Savvy manufacturers never stop researching ways to keep costs down and improve productivity… Whilst the at the start cost of electrical energy tools is without a doubt attractive, pneumatic tools give a lower price tag of ownership and greater throughput over time.


Industrial air grinders provide a totally different value proposition than electric grinders. They are engineered for longevity, efficiency, and above all safety. Air powered grinders are becoming more popular due to the benefits provided with regards to their cost. Adopting air powered grinders brings about greater financial savings through the entire lifetime of the tool.

In this article, we explore 5 clear benefits afforded through industrial grade pneumatic grinders.

1. No Risk of electrical Shock
Grinders of most varieties are frequently utilized in environments where moisture, conductive materials, and flammable liquids are present. Damaged cords and wires pose a hazard to operator safety due to electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, for example acetone, to clean and prep metals before welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when working in confined spaces such as those found in the mining and tank cleaning industries. On the other hand, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer workplace which cuts down on chance of generating OSHA violations. In other words, air tools are safer than electric tools because an aura hose will never emit a spark and can be employed in wet conditions.

2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders give a better chance to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower within a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools from the wattage fed into their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications could be that the power fed in the motor is not same wattage that comes to fruition at the spindle of the tool. In fact, only 50% to 60% in the rated wattage actually concerns the abrasive or accessory. On the other hand, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will give that very same level of chance to the tool.

3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output is really a priority for your operation (then when don’t you find it?), pneumatic grinders may help you meet your purpose. When working with grinders regardless of the sort, Revolutions For each minute (RPM) play a critical role inside 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 are equipped with a speed control mechanism, (also known as a governor), that ensures proper RPM by governing the air flow to the tool. As the operator places downward pressure around the abrasive, the governor “opens up”, increasing ventilation towards the motor and ensuring the proper spindle speed.

4. 100% Duty Cycle + High end in Harsh Environments
Mitch Burdick, a Product Manager for Tools 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 should be respected. Without a periodic rest, the temperature generated from the motor itself will diminish performance and eventually cause premature tool failure. In reality, for every 4 minutes running, an electrical grinder was designed to have one minute of rest.

Furthermore, the generation of particles is inherent in any material removal process. Using the open grate style motor compartments required for cooling, electric tool motors tend to be prone to the buildup of dust and debris. In contrast, Industrial Grade Air Tools are made especially for use in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they’re made to run Round the clock Seven days a week (when combined with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not Abs plastic, fiberglass driving them to more up against the impact from repeated drops. Pneumatic grinders can also be used underwater if the exhaust is vented higher than the surface!

5. Simplicity of Servicing and Sustainability
An advert grade grinder is very little disposable device as well as doesn’t immediately result in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders could be tuned up and turn into periodically rebuilt often over. The normal electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, at the very least, a fresh pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a truly 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 are available that contain the most typical wear parts.
