Savvy manufacturers never stop looking for ways to keep costs down and improve productivity… Whilst the beforehand tariff of electricity tools is undoubtedly attractive, pneumatic tools provide a lower price tag of ownership and greater throughput in the lon run.
Industrial air grinders give you a very different value proposition than electric grinders. They’re engineered for longevity, efficiency, and most importantly safety. Air powered grinders are gaining in popularity because of the benefits provided in relation to their cost. Adopting air powered grinders results in greater cost savings through the lifetime 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 coming from all varieties are generally utilized 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 count on flammable chemicals, including acetone, to scrub and prep metals before welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when employed in confined spaces including those perfectly located at 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 build a safer work place which cuts down the likelihood of generating OSHA violations. In other words, air tools are safer than electric tools because an aura hose will never emit a spark and is utilized in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders provide a better chance to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the effectiveness of their tools with 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. The truth is, only 50% to 60% with the rated wattage actually concerns the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will offer that very same volume of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output is often a priority for your operation (when is it not?), pneumatic grinders may help you meet your goals. When you use grinders of any type, Revolutions Per Minute (RPM) play a crucial role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally with a specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (also called a governor), that ensures proper RPM by regulating the air flow on the tool. Because operator places downward pressure about the abrasive, the governor “opens up”, increasing air flow on the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + High end in Harsh Environments
Mitch Burdick, an item 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 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 warmth generated by the motor itself will diminish performance and finally cause premature tool failure. Actually, for every single 4 minutes running, an electrical grinder is made to get one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. Together with the open grate style motor compartments needed for cooling, electric tool motors will be more vunerable to the accumulation of the dust and dirt. On the other hand, 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 100% duty cycle, meaning they may be designed to run Around the clock Seven days a week (when used in combination with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not ABS plastic which makes them more resistant to the impact from repeated drops. Pneumatic grinders could be used underwater if your exhaust is vented higher than the surface!
5. Simple Servicing and Sustainability
An advert grade grinder is very little disposable machine as well as doesn’t immediately end up in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders might be tuned up and turn into periodically rebuilt many times over. The typical electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, to start, a new list 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 can be obtained that includes the most common wear parts.
