Savvy manufacturers never stop researching to reduce costs and improve productivity… While the at the start tariff of electrical power tools is undoubtedly attractive, pneumatic tools offer a lower sum total of ownership and greater throughput over time.
Industrial air grinders provide a very different value proposition than electric grinders. They are engineered for longevity, efficiency, and most importantly safety. Air powered grinders are becoming more popular as a result of benefits provided in terms of their cost. Adopting air powered grinders brings about greater cost benefits throughout the duration of the tool.
In this article, we explore 5 clear benefits afforded by the use of industrial grade pneumatic grinders.
1. Non-recourse of Electric Shock
Grinders of varieties are generally found in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a danger to operator safety due to electrical shock. Furthermore, metal fabricators often count on flammable chemicals, including acetone, to wash and prep metals ahead of welding. Pools of spilled liquids can readily be ignited by faulty electrical cords. Additionally, vapor concentrations could be higher when in confined spaces like those found 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 develop a safer workplace which lessens the probability of generating OSHA violations. Simply put, air tools are safer than electric tools because an aura hose will not emit a spark and is employed in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools through the wattage fed to their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications would be that the power fed in the motor is not same wattage that concerns the spindle of the tool. In fact, only 50% to 60% with the rated wattage actually arrives to the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will give that same amount of power 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 the operation (then when don’t you find it?), pneumatic grinders can help you meet your goals. Whenever using grinders regardless of the sort, Revolutions Each minute (RPM) play a critical role from the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to execute optimally in a specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by regulating the ventilation for the tool. Because operator places downward pressure about the abrasive, the governor “opens up”, increasing air-flow to the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a Product 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 a hot sun doesn’t help either.” By their very nature electric motors use a rated duty cycle which should be respected. With out a periodic rest, heat generated through the motor itself will diminish performance and in the end cause premature tool failure. The truth is, for every 4 minutes running, a power grinder is made to have one minute of rest.
Furthermore, the generation of particles is built into any material removal process. With all the open grate style motor compartments needed for cooling, electric tool motors are more vulnerable to the accumulation of debris and dust. As opposed, Industrial Grade Air Tools are created specifically for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning they are built to run Round the clock Seven days a week (when in combination with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Fibreglass causing them to be more resistant to the impact from repeated drops. Pneumatic grinders could be used underwater if your exhaust is vented across the surface!
5. Simplicity of Servicing and Sustainability
A commercial grade grinder is very little disposable device and doesn’t immediately find themselves in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders may be updated and stay periodically rebuilt more often than not over. The normal electric tool maintenance interval is between 60 and 120 hours and 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 very industrial grade air grinder can increase to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits can be obtained that have the most frequent wear parts.
