Savvy manufacturers never stop looking for ways to reduce costs and improve productivity… As the in advance price of electric power tools is certainly attractive, pneumatic tools give you a lower price tag of ownership and greater throughput over time.
Industrial air grinders give you a different value proposition than electric grinders. They’re engineered for longevity, efficiency, and above all safety. Air powered grinders are gaining in popularity as a result of benefits provided in relation to their cost. Adopting air powered grinders results in greater cost savings through the entire lifetime of the tool.
On this page, we explore 5 obvious benefits afforded using industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders coming from all varieties are generally used in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a risk to operator safety caused by electrical shock. Furthermore, metal fabricators often count on flammable chemicals, like acetone, to wash and prep metals prior to welding. Pools of spilled liquids can readily 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, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer workplace which cuts down on likelihood of generating OSHA violations. In other words, air tools are safer than electric tools because an aura hose will never emit a spark and could be employed in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders give you a better chance to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in the smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools through the wattage fed into 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 arrives to the spindle of the tool. In fact, only 50% to 60% of the rated wattage actually concerns the abrasive or accessory. On the other hand, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will offer that very same volume of power 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 (when don’t you find it?), pneumatic grinders can help you meet your goals. When making use of grinders of all sorts, Revolutions Per Minute (RPM) play a vital role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally at the specific RPM. Fortunately, modern pneumatic grinders have a speed control mechanism, (also known as a governor), that ensures proper RPM by money air flow on the tool. Since the operator places downward pressure around the abrasive, the governor “opens up”, increasing air flow towards the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + High Performance 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 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 has to be respected. Without a periodic rest, the heat generated from the motor itself will diminish performance and eventually cause premature tool failure. Actually, for each and every 4 minutes running, an electrical grinder is designed to have one minute of rest.
Furthermore, the generation of particles is built into any material removal process. With all the open grate style motor compartments essential for cooling, electric tool motors are more susceptible to the buildup of debris and dust. As opposed, Industrial Grade Air Tools are created specifically for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning these are built to run Twenty-four hours a day 7 days a week (when used with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not ABS plastic causing them to be more up against the impact from repeated drops. Pneumatic grinders could be used underwater in the event the exhaust is vented above the surface!
5. Simple Servicing and Sustainability
An industrial grade grinder isn’t a disposable item of equipment as well as doesn’t immediately end up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders can be updated and be periodically rebuilt many times over. The average electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at a minimum, a 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 amass 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 frequent wear parts.
