Savvy manufacturers never stop researching ways to reduce costs and improve productivity… Whilst the up front expense of electrical energy tools is certainly attractive, pneumatic tools give you a lower sum total of ownership and greater throughput over time.
Industrial air grinders offer a totally different value proposition than electric grinders. They are engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are increasing in popularity due to the benefits provided in terms of their cost. Adopting air powered grinders results in greater cost benefits through the entire time of the tool.
In this post, we explore 5 clear benefits afforded through industrial grade pneumatic grinders.
1. Non-recourse of electrical Shock
Grinders of most varieties are often employed in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a hazard to operator safety resulting from electrical shock. Furthermore, metal fabricators often depend on flammable chemicals, such as acetone, to clean and prep metals before welding. Pools of spilled liquids can readily be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when employed in confined spaces for example those based in the mining and tank cleaning industries. In comparison, air tools require no electricity, as well as their rotary vane air motors generate no spark. Pneumatic grinders therefore develop a safer work place which decreases the odds of generating OSHA violations. To put it simply, air tools are safer than electric tools because an air hose won’t emit a spark and can be used in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders offer a better chance to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower in a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength of their tools through the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications could be that the power fed into the motor isn’t the same wattage that involves the spindle of the tool. Actually, only 50% to 60% with the rated wattage actually involves the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will supply that same volume of capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for just a moment. If increasing worker output can be a priority for the operation (and when don’t you find it?), pneumatic grinders will help you meet your goals. Whenever using grinders of any type, Revolutions Per Minute (RPM) play an important role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally with a specific RPM. Fortunately, modern pneumatic grinders are equipped with a speed control mechanism, (also known as a governor), that ensures proper RPM by money air flow towards the tool. Since the operator places downward pressure on the abrasive, the governor “opens up”, increasing ventilation towards the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, something 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 under a hot sun doesn’t help either.” By their very nature electric motors have a very rated duty cycle which should be respected. With out a periodic rest, the temperature generated through the motor itself will diminish performance and eventually cause premature tool failure. In reality, for every single 4 minutes running, an electric powered grinder is designed to get one minute respite.
Furthermore, the generation of particles is built into any material removal process. Together with the open grate style motor compartments necessary for cooling, electric tool motors will be more prone to the buildup of the dust and dirt. On the other hand, Industrial Grade Air Tools were created specifically for use within foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning they’re meant to run Twenty-four hours a day 7 days a week (when combined with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not Fibreglass driving them to more up against the impact from repeated drops. Pneumatic grinders could be used underwater if the exhaust is vented higher than the surface!
5. Easy Servicing and Sustainability
A commercial grade grinder is not an disposable device and doesn’t immediately end up in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders may be updated and be periodically rebuilt more often than not over. The common electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a whole new list 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 can be obtained that contain the most frequent wear parts.
