Savvy manufacturers never stop searching for ways to keep costs down and improve productivity… Even though the at the start price of electricity tools is certainly attractive, pneumatic tools give a lower price tag of ownership and greater throughput in the lon run.
Industrial air grinders offer a very different value proposition than electric grinders. They are engineered for longevity, efficiency, and more importantly safety. Air powered grinders are rising in popularity due to benefits provided regarding their cost. Adopting air powered grinders ends in greater cost benefits through the entire duration of the tool.
In this post, we explore 5 clear benefits afforded by way of industrial grade pneumatic grinders.
1. Non-recourse of electrical Shock
Grinders of most varieties are often used in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a threat to operator safety resulting from electrical shock. Furthermore, metal fabricators often count on flammable chemicals, such as acetone, to scrub and prep metals just before welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when working in confined spaces like those perfectly located at the mining and tank cleaning industries. In contrast, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore produce a safer workplace which cuts down the likelihood 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 utilized in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders provide a better power to weight ratio than electric grinders. To put it simply, pneumatic grinders produce more horsepower within a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength of their tools by 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 the motor is not the same wattage that comes to fruition at the spindle in the tool. The truth is, only 50% to 60% with the rated wattage actually concerns the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will offer that very same amount of capacity to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output can be a priority for your operation (so when is it not?), pneumatic grinders can help you meet your goals. Whenever using grinders of any type, Revolutions For each minute (RPM) play a critical role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally at the specific RPM. Fortunately, modern pneumatic grinders are equipped with a speed control mechanism, (also called a governor), that ensures proper RPM by money ventilation for the tool. Because the operator places downward pressure for the abrasive, the governor “opens up”, increasing air flow towards the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a Product 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 have a very rated duty cycle which has to be respected. With out a periodic rest, heat generated through the motor itself will diminish performance and finally cause premature tool failure. In fact, for each 4 minutes running, an electrical grinder is made to have one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. Using the open grate style motor compartments essential for cooling, electric tool motors tend to be more prone to the buildup of the dust and dirt. In comparison, Industrial Grade Air Tools are created especially for used 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 designed to run Around the clock 7 days a week (when used in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not ABS plastic driving them to more resistant to the impact from repeated drops. Pneumatic grinders could even be used underwater if the exhaust is vented over the surface!
5. Simple Servicing and Sustainability
An industrial grade grinder is very little disposable device and immediately find themselves in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders might be updated and become periodically rebuilt many times over. The average electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a 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 increase to 2000 hours between tune ups. When it’s time to service your air tools, convenient and clearly labeled kits can be purchased that includes the most common wear parts.
