Savvy manufacturers never stop researching to reduce costs and improve productivity… While the in advance expense of electricity tools is without question attractive, pneumatic tools provide a lower total price 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 even more importantly safety. Air powered grinders are becoming more popular due to benefits provided regarding their cost. Adopting air powered grinders ends in greater personal savings through the entire lifetime of the tool.
On this page, we explore 5 clear benefits afforded by the use of industrial grade pneumatic grinders.
1. No recourse of electrical Shock
Grinders of varieties are generally utilized in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a hazard to operator safety as a result of electrical shock. Furthermore, metal fabricators often depend upon flammable chemicals, including acetone, to scrub and prep metals ahead of welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when in confined spaces including those found in the mining and tank cleaning industries. In comparison, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore produce a safer workplace which lessens the likelihood of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose won’t ever emit a spark and could be utilized in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower inside a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the effectiveness of their tools by the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications could be that the power fed to the motor isn’t the same wattage that comes to fruition at the spindle of the tool. In fact, only 50% to 60% of the rated wattage actually concerns the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will offer 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 is often a priority on your operation (then when isn’t it?), pneumatic grinders can assist you meet your purpose. Whenever using grinders of any type, Revolutions Each and every minute (RPM) play an important role from 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 include a speed control mechanism, (also called a governor), that ensures proper RPM by controlling the ventilation on the tool. As the operator places downward pressure on the abrasive, the governor “opens up”, increasing venting towards the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, something Manager for Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and also heat – dropping them in water, or baking them under a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which must be respected. With no periodic rest, heat generated from the motor itself will diminish performance and ultimately cause premature tool failure. In fact, for every single 4 minutes running, an electric grinder was designed to have one minute respite.
Furthermore, the generation of particles is built into any material removal process. Together with the open grate style motor compartments essential for cooling, electric tool motors tend to be vulnerable to the buildup of dust and debris. On the other hand, Industrial Grade Air Tools were created particularly for use within foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools use a 100% duty cycle, meaning they are built to run Twenty-four hours a day 7 days a week (when in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Fibreglass which makes them more up against the impact from repeated drops. Pneumatic grinders could even be used underwater in the event the exhaust is vented above the surface!
5. Simplicity of Servicing and Sustainability
A commercial grade grinder isn’t a disposable item of equipment as well as doesn’t immediately result in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders could be updated and be periodically rebuilt more often than not over. The typical electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, to start, a whole new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very industrial grade air grinder can increases to 2000 hours between tune ups. When it’s time to service your air tools, convenient and clearly labeled kits are available that contain the most common wear parts.
