Savvy manufacturers never stop researching to keep costs down and improve productivity… Whilst the at the start price of electric power tools is certainly attractive, pneumatic tools offer a lower sum total of ownership and greater throughput over time.
Industrial air grinders provide a totally different value proposition than electric grinders. They’re engineered for longevity, efficiency, and above all safety. Air powered grinders are becoming more popular because of the benefits provided in relation to their cost. Adopting air powered grinders leads to greater personal savings during the entire duration of the tool.
In this article, we explore 5 clear benefits afforded by the use of industrial grade pneumatic grinders.
1. No Risk of electrical Shock
Grinders of most varieties are often employed in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a risk to operator safety due to electrical shock. Furthermore, metal fabricators often count on flammable chemicals, for example acetone, to clean and prep metals prior to welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when in confined spaces like those located in the mining and tank cleaning industries. On the other hand, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore develop a safer work place which lessens the likelihood of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose won’t ever emit a spark and is employed in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower inside a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the effectiveness of their tools with the wattage fed to their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications is that the power fed in the motor isn’t the same wattage that comes to fruition at the spindle from the tool. The truth is, only 50% to 60% of the rated wattage actually concerns the abrasive or accessory. On the other hand, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will supply that very same volume of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output can be a priority for your operation (so when is it not?), pneumatic grinders can help you meet your purpose. Whenever using grinders of all sorts, Revolutions Each and every minute (RPM) play a critical role from the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally at the specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (also known as a governor), that ensures proper RPM by governing the venting to the tool. As the operator places downward pressure for the abrasive, the governor “opens up”, increasing venting towards the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, an item Manager for Saws 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 use a rated duty cycle which has to be respected. Without a periodic rest, the temperature generated by the motor itself will diminish performance and eventually cause premature tool failure. In reality, for each 4 minutes running, an electrical grinder is designed to have one minute of sleep.
Furthermore, the generation of particles is inherent in any material removal process. Together with the open grate style motor compartments essential for cooling, electric tool motors are more susceptible to the buildup of debris and dust. In contrast, Industrial Grade Air Tools are designed specifically for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they may be meant to run Around the clock Seven days a week (when used in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Fibreglass making them more resistant to the impact from repeated drops. Pneumatic grinders can also be used underwater if your exhaust is vented over the surface!
5. Simplicity of Servicing and Sustainability
A commercial grade grinder is not a disposable piece of equipment and doesn’t immediately finish up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders may be tuned up and stay periodically rebuilt often over. The typical electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, to start, a whole new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a totally industrial grade air grinder can amass to 2000 hours between tune ups. When it’s time to service your air tools, convenient and clearly labeled kits can be purchased that includes the commonest wear parts.
