Savvy manufacturers never stop researching to reduce costs and improve productivity… As the up front cost of electrical energy tools is undoubtedly attractive, pneumatic tools give you a lower total price of ownership and greater throughput in the lon run.
Industrial air grinders provide a very different value proposition than electric grinders. They’re engineered for longevity, efficiency, and more importantly safety. Air powered grinders are increasing in popularity because of the benefits provided with regards to their cost. Adopting air powered grinders results in greater personal savings through the entire duration of the tool.
In this article, we explore 5 clear benefits afforded by way of industrial grade pneumatic grinders.
1. No Risk of electrical Shock
Grinders of all varieties are likely to be found in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a danger to operator safety caused by electrical shock. Furthermore, metal fabricators often depend on flammable chemicals, such as acetone, to scrub and prep metals prior to welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when employed in confined spaces such as those located in the mining and tank cleaning industries. In contrast, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work place which cuts down on likelihood of generating OSHA violations. Simply put, air tools are safer than electric tools because an aura hose will not emit a spark and is utilized in wet conditions.
2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders give a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower within a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the effectiveness of their tools through the wattage fed into their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications is that the power fed in to the motor isn’t same wattage that concerns the spindle in the tool. In reality, only 50% to 60% from 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 same amount of capability 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 the operation (then when isn’t it?), pneumatic grinders can help you meet your primary goal. When making use of grinders of all sorts, Revolutions Per Minute (RPM) play a critical role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to execute optimally at the specific RPM. Fortunately, modern pneumatic grinders come with a speed control mechanism, (also known as a governor), that ensures proper RPM by money venting on the tool. Because the operator places downward pressure around the abrasive, the governor “opens up”, increasing air-flow for the motor and ensuring the proper spindle speed.
4. 100% Duty Cycle + Powerful 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 also heat – dropping them in water, or baking them under a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which has to be respected. With out a periodic rest, the heat generated by the motor itself will diminish performance and finally cause premature tool failure. In reality, for every single 4 minutes running, an electric powered grinder was created 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 necessary for cooling, electric tool motors are more susceptible to the buildup of the dust and dirt. As opposed, 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’re made to run 24 hours a day 7 days a week (when used in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Abs plastic, fiberglass causing them to be more up against the impact from repeated drops. Pneumatic grinders can even be used underwater in the event the exhaust is vented above the surface!
5. Simple Servicing and Sustainability
An advertisement grade grinder is not a disposable piece of equipment as well as doesn’t immediately result in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders could be updated and stay periodically rebuilt more often than not over. The normal electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, at a minimum, a 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 run up to 2000 hours between tune-ups. When it’s time to service your air tools, convenient and clearly labeled kits can be found that have the most common wear parts.
