Savvy manufacturers never stop researching to reduce costs and improve productivity… While the in advance expense of electrical energy tools is certainly attractive, pneumatic tools offer a lower price tag of ownership and greater throughput in the long run.
Industrial air grinders give you a totally different value proposition than electric grinders. They’re engineered for longevity, efficiency, and more importantly safety. Air powered grinders are gaining in popularity due to the benefits provided in terms of their cost. Adopting air powered grinders results in greater financial savings through the time of the tool.
In the following paragraphs, we explore 5 obvious benefits afforded by way of industrial grade pneumatic grinders.
1. Non-recourse of Electric Shock
Grinders of all varieties are likely to be utilized in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a danger to operator safety resulting from electrical shock. Furthermore, metal fabricators often count on flammable chemicals, like acetone, to scrub and prep metals before welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when working in confined spaces like those located in the mining and tank cleaning industries. On the other hand, air tools require no electricity, as well as their rotary vane air motors generate no spark. Pneumatic grinders therefore develop a safer workplace which cuts down on likelihood of generating OSHA violations. In other words, air tools are safer than electric tools because a cloak hose will never emit a spark and can be used in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders offer a better capacity to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower within a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the potency of their tools with 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 is not same wattage that comes to fruition at the spindle of the tool. In fact, only 50% to 60% of the rated wattage actually arrives to the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will offer that same level of power to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside if you’ll. If increasing worker output is often a priority to your operation (when isn’t it?), pneumatic grinders can assist you meet your purpose. When working with 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 execute optimally at the specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by regulating the air flow to the tool. Since the operator places downward pressure around the abrasive, the governor “opens up”, increasing air flow towards the motor and ensuring the best 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 as well as heat – dropping them in water, or baking them within a hot sun doesn’t help either.” By their very nature electric motors use a rated duty cycle which should be respected. With no periodic rest, the temperature generated by the motor itself will diminish performance and eventually cause premature tool failure. In fact, for each 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. Using the open grate style motor compartments necessary for cooling, electric tool motors tend to be vulnerable to the accumulation of debris and dust. As opposed, Industrial Grade Air Tools are made designed for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning these are meant to run Round the clock 7 days a week (when combined with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Fibreglass which makes them more resistant to the impact from repeated drops. Pneumatic grinders could even be used underwater when the exhaust is vented over the surface!
5. Simple Servicing and Sustainability
An industrial grade grinder is not a disposable item of equipment and immediately finish up in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders may be tuned up and stay periodically rebuilt often times over. The common electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a whole new pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a totally industrial grade air grinder can increase to 2000 hours between tune-ups. When it’s time to service your air tools, convenient and clearly labeled kits can be obtained that contain the commonest wear parts.
