|Why do you need an Air Compressor?
An Air Compressor is a versatile tool that can perform a variety of tasks when attached to
Air tools, also known as pneumatic tools, Air tools have several advantages over electric power tools: they have more torque and power than conventional power tools, more durability because of fewer moving parts, and they’re easy to use.
You can use an Air Compressor with Air tools for maintenance and craft projects around the house, repair jobs in the garage, construction projects on the job site, or industrial projects in the shop. Using pneumatic nail guns hammers, other
Air tools, CNC machine, Pneumatic valve, Air guns, Chillers and Production Air like-Blow molding etc,
Air Compressors are available in a wide array of sizes and styles. Choosing the one that’s right for you is really a matter of how it will be used and personal preference. Ask yourself the following before going any further.
- Is there a ready electrical supply?
- Will you be working in confined or unventilated areas?
- Which tools will you want your Compressor to operate?
How to select the right Air Compressor For the job
The type of Air Compressor you need will depend on the above factors, especially which tools your will want your
Air Compressor to operate. Most Air tools have specific requirements for volume and pressure, while
Air Compressors are rated on the following four factors:
PSI-Pound per square inch: This is the measure of
Air pressure delivered by your Compressor. The higher the PSI, the further the
Air can be compressed meaning a larger volume of compressed
Air can be stored in the tank.
CFM-Cubic Feet per Minute: This is the volume of Air that your
Compressor can pump in one minute a specific working pressure. High CFM ratings means a
Compressor can provide more Air-making higher CFM units more practical for larger applications
A thumb Rule
1 HP=approx 4cfm@90PSI (6 to 7 kg/cm2)
HP – Horsepower: This is the unit of measurement for the power your
Air Compressor’s motor produces. Higher horsepower engines produce greater PSI and are capable of carrying a heavier workload.
Tank Size: Units with more powerful motors and larger tanks (measured in gallons) can generate higher levels of PSI for longer amounts of time, providing greater power to your air tools.
Tank Capacity- A thumb rule is to have 5 Liters every 1 CFM of
Air Compressor output
To choose an Air Compressor that will meet the requirements for your tools to function properly, use this formula. Select the tool that requires the highest volume cubic feet per minute (CFM) at the highest pounds per square inch (PSI). Then add 50% to the require CFM as a safety margin.
Example- If a tool requires 3 CFM at 90 PSI; choose an
Air Compressor that provides at a minimum 4.5 CFM at 90 PSI.
