Savvy manufacturers never stop researching to keep costs down and improve productivity… Even though the at the start price of electrical energy tools is undoubtedly attractive, pneumatic tools give a lower price tag of ownership and greater throughput over the long term.

Industrial air grinders give a completely different value proposition than electric grinders. They may be engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are gaining in popularity due to benefits provided in terms of their cost. Adopting air powered grinders leads to greater cost benefits during the entire life of the tool.

In this post, we explore 5 clear cut benefits afforded using industrial grade pneumatic grinders.

1. Non recourse of Electric Shock
Grinders of all varieties are likely to be employed in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a hazard to operator safety due to electrical shock. Furthermore, metal fabricators often depend upon flammable chemicals, for example acetone, to clean and prep metals prior to welding. Pools of spilled liquids can easily 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 create a safer workplace which lessens the odds of generating OSHA violations. In other words, air tools are safer than electric tools because a cloak hose will not emit a spark and is utilized in wet conditions.

2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower in the lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength of their tools by the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications would be that the power fed to the motor is not the same wattage that comes to fruition at the spindle from the tool. In fact, only 50% to 60% of the rated wattage actually arrives to 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 capacity to the tool.

3. Increased Productivity
Let’s put ergonomics and ratios aside if you’ll. If increasing worker output is a priority for your operation (then when is it not?), pneumatic grinders can assist you meet your primary goal. Whenever using grinders regardless of the sort, Revolutions Each minute (RPM) play an important role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally with a specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by regulating the venting to the tool. Because the operator places downward pressure on the abrasive, the governor “opens up”, increasing air-flow on the motor and ensuring the best spindle speed.

4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, a Product Manager for Power Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them under a hot sun doesn’t help either.” By their very nature electric motors use a rated duty cycle which must be respected. Without having a periodic rest, the temperature generated through the motor itself will diminish performance and ultimately cause premature tool failure. The truth is, for every 4 minutes running, an electric powered grinder was created to have one minute rest.

Furthermore, the generation of particles is built into any material removal process. Together with the open grate style motor compartments needed for cooling, electric tool motors are more vunerable to the buildup of debris and dust. In contrast, Industrial Grade Air Tools are made especially for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools possess a 100% duty cycle, meaning they may be built to run Around the clock 7 days a week (when combined with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Fibreglass making them 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. Simple Servicing and Sustainability
An advert grade grinder is not a disposable item of equipment and immediately result in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders could be updated and become periodically rebuilt often times over. The average electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, at a minimum, a whole new set of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a really industrial grade air grinder can increases 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 typical wear parts.
