Savvy manufacturers never stop searching for ways to keep costs down and improve productivity… As the at the start expense of electrical energy tools is certainly attractive, pneumatic tools give you a lower sum total of ownership and greater throughput in the long run.
Industrial air grinders give you a completely different value proposition than electric grinders. These are engineered for longevity, efficiency, and more importantly safety. Air powered grinders are increasing in popularity due to the benefits provided with regards to their cost. Adopting air powered grinders leads to greater cost savings through the duration of the tool.
In the following paragraphs, we explore 5 clear cut benefits afforded through industrial grade pneumatic grinders.
1. Non-recourse of electrical Shock
Grinders coming from all varieties are likely to be employed in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a risk to operator safety due to electrical shock. Furthermore, metal fabricators often count on flammable chemicals, for example acetone, to scrub and prep metals prior to welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when doing work 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 produce a safer work place which lessens the chance of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose won’t emit a spark and could be employed in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders give you a better capability to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower in a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the strength of their tools with the wattage fed inside 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 to the motor is not the same wattage that involves the spindle of the tool. The truth is, only 50% to 60% in the rated wattage actually concerns the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will supply that same volume of capacity to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is really a priority on your operation (and when don’t you find it?), pneumatic grinders will help you meet your primary goal. Whenever using grinders regardless of the sort, Revolutions Per Minute (RPM) play a critical role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to perform optimally in a specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by money venting for the tool. As the operator places downward pressure on the abrasive, the governor “opens up”, increasing air flow towards the motor and ensuring the right 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 also heat – dropping them in water, or baking them with a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which should be respected. With no periodic rest, heat generated by the motor itself will diminish performance and in the end cause premature tool failure. The truth is, for each 4 minutes running, an electric powered grinder is designed to have one minute respite.
Furthermore, the generation of particles is inherent in any material removal process. With the open grate style motor compartments necessary for cooling, electric tool motors will be more susceptible to the buildup of the dust and dirt. In comparison, Industrial Grade Air Tools are made specifically for used 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 may be made to run Twenty-four hours a day 7 days a week (when used in combination with a filter regulator lubricator). Air tool housings are constructed of aluminum or steel, not Abs plastic, fiberglass causing them to be more resistant to the impact from repeated drops. Pneumatic grinders could be used underwater when the exhaust is vented higher than the surface!
5. Simple Servicing and Sustainability
An advert grade grinder is very little disposable piece of equipment and does not immediately finish up in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders could be tuned up and stay periodically rebuilt often over. The normal electric tool maintenance interval is between 60 and 120 hours and the tool will typically need, at a minimum, a whole new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a truly industrial grade air grinder can increases to 2000 hours between tune-ups. When the time comes to service your air tools, convenient and clearly labeled kits are available that includes the most common wear parts.
