Several Advantages Of Using Air Powered Grinders In Place Of Electric

Posted by

Savvy manufacturers never stop looking for ways to keep costs down and improve productivity… As the up front expense of electric power tools is without question attractive, pneumatic tools offer a lower price tag of ownership and greater throughput over the long term.


Industrial air grinders offer a different value proposition than electric grinders. These are engineered for longevity, efficiency, and most importantly safety. Air powered grinders are becoming more popular because of the benefits provided regarding their cost. Adopting air powered grinders results in greater cost benefits through the duration of the tool.

In this post, we explore 5 clear benefits afforded using industrial grade pneumatic grinders.

1. Non-recourse of Electric Shock
Grinders coming from 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 as a result of electrical shock. Furthermore, metal fabricators often depend upon flammable chemicals, like acetone, to clean and prep metals before welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when doing work in confined spaces including those found in the mining and tank cleaning industries. As opposed, air tools require no electricity, as well as their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work environment which decreases the probability of generating OSHA violations. Simply put, air tools are safer than electric tools because an aura hose won’t emit a spark and could be employed in wet conditions.

2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders give a better capacity to weight ratio than electric grinders. To put it simply, pneumatic grinders produce more horsepower within a smaller and lighter 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 stated in electric tool specifications could be that the power fed in the motor is not same wattage that comes to fruition at the spindle in the tool. Actually, only 50% to 60% of the rated wattage actually comes to fruition at the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will provide that very same amount of power to the tool.

3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is often a priority to your operation (so when don’t you think?), pneumatic grinders can help you meet your purpose. When you use grinders of any type, Revolutions Per Minute (RPM) play a vital role from 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 are equipped with a speed control mechanism, (also referred to as a governor), that ensures proper RPM by controlling the ventilation to the tool. Because operator places downward pressure around the abrasive, the governor “opens up”, increasing ventilation to the motor and ensuring the proper spindle speed.

4. 100% Duty Cycle + Powerful 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 warmth – dropping them in water, or baking them within hot sun doesn’t help either.” By their very nature electric motors possess a rated duty cycle which has to be respected. With out a periodic rest, the temperature generated with the motor itself will diminish performance and finally cause premature tool failure. The truth is, for every 4 minutes running, an electric powered grinder is designed to have one minute rest.

Furthermore, the generation of particles is inherent in any material removal process. Using the open grate style motor compartments required for cooling, electric tool motors tend to be vulnerable to the accumulation of dust and debris. In contrast, Industrial Grade Air Tools were created especially for utilization 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 meant to run Around the clock Seven days a week (when in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Abs plastic, fiberglass making them more up against the impact from repeated drops. Pneumatic grinders can even be used underwater if your exhaust is vented across the surface!

5. Easy Servicing and Sustainability
An industrial grade grinder is not a disposable machine as well as doesn’t immediately finish up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders can be updated and turn into periodically rebuilt often over. The normal electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, to start, 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 run up to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits are available that contain the most typical wear parts.
