Savvy manufacturers never stop researching ways to keep your charges down and improve productivity… As the in advance price of electrical power tools is without a doubt attractive, pneumatic tools give you a lower total price of ownership and greater throughput over the long term.
Industrial air grinders provide a totally 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 in relation to their cost. Adopting air powered grinders results in greater cost benefits through the time of the tool.
In the following paragraphs, we explore 5 clear cut benefits afforded using industrial grade pneumatic grinders.
1. Non-recourse of electrical Shock
Grinders of most varieties are generally used in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a threat to operator safety due to electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, such as acetone, to scrub and prep metals just before welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations could be higher when working in confined spaces such as those perfectly located at the mining and tank cleaning industries. On the other hand, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer workplace which decreases the odds of generating OSHA violations. To put it simply, air tools are safer than electric tools because a cloak hose will never emit a spark and is utilized in wet conditions.
2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders provide a better capacity to weight ratio than electric grinders. To put it simply, pneumatic grinders produce more horsepower in the lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength of their tools with the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications would be that the power fed to the motor isn’t the same wattage that involves the spindle of the tool. In fact, only 50% to 60% from the rated wattage actually concerns the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will supply that same level of capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside if you’ll. If increasing worker output is a priority to your operation (then when isn’t it?), pneumatic grinders can help you meet your goals. When you use grinders of any type, Revolutions For each minute (RPM) play a crucial role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally at a specific RPM. Fortunately, modern pneumatic grinders come with 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 for the abrasive, the governor “opens up”, increasing ventilation towards the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, a product or service Manager for Power Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them under a hot sun doesn’t help either.” By their very nature electric motors possess a rated duty cycle which should be respected. Without a periodic rest, heat generated from the motor itself will diminish performance and in the end cause premature tool failure. In fact, for every 4 minutes running, a power grinder is designed to get one minute of sleep.
Furthermore, the generation of particles is inherent in any material removal process. With the open grate style motor compartments required for cooling, electric tool motors tend to be more vulnerable to the buildup of the dust and dirt. On the other hand, Industrial Grade Air Tools were created 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’re made 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, fiberglass which makes them more up against the impact from repeated drops. Pneumatic grinders can also be used underwater when the exhaust is vented above the surface!
5. Easy Servicing and Sustainability
An industrial grade grinder is not an disposable piece of equipment and does not immediately result in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders can be updated 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, at a minimum, a fresh group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a totally 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 found that contain the most typical wear parts.
