Another fact to consider is how much of your equipment will be running at the same time? Download a copy of our Air Consumption Calculator for a listing of the air demand of most air driven tools and a handy calculator to figure out what your operation needs, then use the air flow rate calculator.
Read our blog post about Properly Sizing a System to learn more. The easier way to do all this is simply use our air compressor CFM calculation formula above and it will do all the work for you. Another easy way to calculate your CFM is by using an airflow meter.
This will give you the amount of flow and the pressure that is coming out of a fitting. Flow meters can be installed on individual pieces of equipment or complete systems to provide an instant reading of actual usage. For a more accurate reading, a receiver tank should be installed near the flow meter to even out peaks and valleys in the data. There are different types of flow meters that can be used for point-of-use measuring, and in-line measuring.
VIP Instruments has a vast array of different flow meters. The air gauge on an industrial compressor typically displays PSI within the compressed air system. Ensuring the successful execution of any application requires supplying the respective application with sufficient air flow CFM at the correct pressure PSI.
In a compressed air system, the amount of pressure has a direct impact on the rate of flow. How much more compressor HP does the plant need to maintain the required PSI in the plant header? In this example, supplementing the existing compressor with a 7. Since it can be difficult to gauge the appropriate amount of pressure required for a given application, many operators err on the side of overpressurization, ramping up PSI to ensure enough pressure is achieved.
Identifying critical pressure requires experiential knowledge of the given application and understanding of how to read pressure regulators installed on production equipment. A grease gun is also a simple and relatively low-pressure pneumatic tool to operate, as it only requires 4 cfm at 90 psi. People often stare in wonder at furniture, fixtures and artwork comprised of carved and uniquely cut sheet metal.
If you see a metal wall-hanging in the form of a silhouetted sun, moon, flower or animal, chances are it was done by hand with an air metal nibbler. In a similar manner to how X-Acto knives and ion cutters carve shapes out of paper and cardboard, nibblers make cutting metal as easy as cutting paper.
Additionally, nibblers are good for trimming inches off metal surfaces and contouring the corners of otherwise sharp metal ends. When properly guided along sheet metal with minimum arm pressure, an air nibbler requires 4 cfm at 90 psi. Even the smallest of metal and wood objects are sometimes in need of maintenance. A mini die grinder can also be used for moderate-relief wood stenciling and other crafts work.
From sanding tips to buffer wheels, the tool is lightweight regardless of the attachment. A mini die grinder requires 4 to 6 cfm at 90 psi. Comprised of numerous rattling steel needles, air needle scalers have the power to remove weld slag, rust, paint and various other signs of wear from hard surfaces.
If you see welds on a metal bracket, it can all be removed by gently running an air needle scaler back and forth a few times over the surface area. The needle scaler allows you to restore metal surfaces to shiny smoothness in seconds, and it only requires 8 to 16 cfm at 90 psi. Ideal for artisans and industrial woodworkers alike, the round-disc head of the sander moves in ellipses across each surface, which ensures smoothness by never running over the same spots in the same way twice.
With only modest amounts of hand pressure, a pneumatic orbital sander requires 6 to 9 cfm at 90 psi. Perhaps the greatest of all pneumatic tools is the air paint brush, which eliminates the streaks, splotches and inconsistencies that are often hard to prevent when painting by hand.
As one of the most delicate steps in the final stages of vehicle, building and furniture completion, the flow of paint needs to be free of dirt and moisture. These requirements are made possible with a pneumatic airbrush, which allows you to apply layers of paint and glaze at a perfect standard that could never be matched by rollers, brushes or aerosol spray cans.
For some of the finest colors and finishes, an airbrush requires 3 to With its short handle and sideways jack, the socket wrench or ratchet allows you to dislodge bolts in tight, narrow places that would be hard to reach with a larger, perpendicular tool.
For all the money that home mechanics save with this handy tool, the per-size requirements of a 90 psi impact wrench are as follows:. Some people assume that the rivet went the way of the dodo once welding came along, yet the permanent fastener is still used in plenty of industrial applications. For instance, rivets are preferred in constructions where fastening must be as strong as possible, but where weight must be kept to a minimum, such as with airplanes.
A hydraulic riveter can also be used in home construction, such as when attaching corrugated metal roofing. As one of the less consuming pneumatic tools, the hydraulic riveter requires 4 cfm at 90 psi.
Contemporary pneumatic saws average 9, strokes per minute, which allows for speed and precision when cutting through layers of gauge sheet metal, as well as through plates and strips of aluminum, copper and plastic.
From garden ornaments to pipe art, an air-powered speed saw can serve as a vital tool in the construction of various forms of copper and metal crafts, not to mention automotive and industrial applications. In order to run at optimal capacity, an air speed saw requires 5 cfm at 90 psi. When it comes to heavier-duty metal cutting, you need more than a mere nibbler. With an air shear, you can slice, trim and outline sheet metals for industrial and craft projects. An ideal tool for metal workshops of all capacities, an air shear requires 8 to 16 cfm at 90 psi.
When a screw or bolt seems welded into place, the truth is somewhere in the middle. While time and the elements can make a tight bolt impossible for even the strongest person to unscrew manually, an impact wrench will perform the job in a matter of seconds. An impact wrench can also be used for applying or removing hubcaps as well as for putting together and taking apart fences, decks and outdoor structures.
