Learn Basic Facts about Air Tools and Air Compressor
------------------------------------------------------------*-----*-------------------------------------------------------------Air tool is a pneumatic tool. It is either a pneumatic powered tool or air powered tool. The air tools
are usually driven by compressed air supplied from any type of gas compressors. Such
pneumatic tools can also be driven by carbon dioxide (CO 2) compressed and stored in small
cylinders for easy portability. It is quite safe to run pneumatic tools and maintenance of such tools
is also easier compared to electric power tools. Further, pneumatic tools have high power-toweight ratio and hence, a lighter and smaller tool will be able to accomplish the task that large
electric power tools perform.
The pneumatic tools of general grade are quite inexpensive but they have shorter life. Hence,
they are termed in tooling industries as disposable tools. However, the pneumatic tools of
industrial grade are much more expensive but have long life spans. Normally, all pneumatic tools
are cheaper when compared to their equivalent electric power tools. These tools were somewhat
unpopular in the do-it-yourself (DIY) markets earlier but due to the ease of operation and safety,
many DIY people have started using them. Anyhow, manufacturing and industrial settings have
been using pneumatic tools as mandatory equipment for long.
Air tools have certain specific technical terms when it comes to selection of the right tool. Air
pressure measured in psi/bar, free speed in rpm, horse power in hp, air consumption in cfm/scfm
or m3/min, and spindle size, etc. determine the selection of the pneumatic tools. It is compulsory
for all pneumatic tools to have ISO 9001:2008 certifications. Most countries insist on this ISO
9001:2008 certification for import or export of pneumatic tools, along with CE marking on them.
Air Compressor
Air compressors are devices that convert power into kinetic energy. The power source is normally
an electric motor, a gasoline engine or a diesel engine. The air compressors compress and
pressurise the air, which is released in quick and short bursts on command. Several types of air
compression methods are available but the major categories are positive displacement
compression and negative displacement compression. Air compressors are divided into other
minor categories and models based on the following factors.
Types of Air Compressor
By Design and Operational Principle
1. Reciprocating Compressor
2. Turbo Compressor
3. Rotary Screw Compressor
Based on Number of Stages
1. Single Stage Compressor
2. Two Stage Compressor
3. Multi Stage Compressor
Based on Pressure Limits
1. Low Pressure Compressor
2. Medium Pressure Compressor
3. High Pressure Compressor
4. Super High Pressure Compressor
Based on Capacity
1. Low Capacity Compressor
2. Medium Capacity Compressor

3. 3. High Capacity Compressor
Based on Cooling Method
1. Water Cooled Compressor
2. Air Cooled Compressor
Positive Displacement Air Compressors
Positive Displacement air compressors function when air is forced into a chamber and the volume
of the chamber is reduced to achieve air compression. Most of the piston type of air compressors
utilizes this principle of pumping air into air chamber by the continuous motion of pistons. These
compressors use on-way values for guiding the air into the chamber and the air gets compressed.
Another type of positive displacement compression method is used in rotary screw compressors.
Two helical matching screws guide air into the chamber when they turn and the volume of the
chamber gets reduced when the screws turn. Similarly, vane compressors utilize slotted rotors
with varied blade placements for guiding air into the chambers and compress their volumes.
Negative Displacement Air Compressors
Negative displacement air compressor is mainly centrifugal compressor. This compressor uses a
spinning impeller, which accelerates to generate centrifugal force and then decelerates captured
air, pressurising the air.

A BRIEF NOTE ON AIR TOOLS AND THEIR COMPRESSORS
------------------------------------------------------------*-----*-------------------------------------------------------------The Air Tools might be conventional in nature, but there are still many people who prefer using
these kinds of tools to have better results. This category of tools includes different kinds of
equipments like the air sanders and hammers, spray guns, and air wrenches, etc. These
particular naming of the equipments is because of the fact that they are powered by air,
compressed and stored. Many may argue that they are old and have been replaced by the
electrical power tools, but that is not an entirely right notion. These kinds of tools are still in use
and many people rely on them as they are more powerful than their electric counterparts. The
best thing about this kind of tools is that the kind of torque and RPM they provide are way more
than that of the electrical tools. Also, not to forget that they are quite light weighted and easy to
use.
The other aspects
Not only the above mentioned but there are several other reasons which makes the Air Tools
popular among the users. These tools help the users to do the work in a much faster as well as
hassle free manner. They are light weighted and thus are absolutely easy to handle. The
versatility of this kind of tool is an added factor which enhances the list of advantages for this tool.
Also, the tools powered by air are absolutely less expensive and thus buying a tool like this will
not dig a hole in your pocket. Moreover the longevity for the tools powered by air instead of
electricity is worth a mention. These kinds of tools do not have any kind of engine of their own

5. and thus they run with the help of the compressor. The compressors are again like the heart of
the tool and better the compressor better the working of the tool.
The lifeline
The Air Compressors are an extremely important part for your toolkit. While choosing a
compressor, it is extremely important for you to understand the nature as well as the requirement
of your tool. You need to be very keen on the need and purpose of the tools which is in question.
This all is required because of the fact that there are a various kinds of compressors and each
one is suitable for a specific purpose. That is the reason you should be very careful and choose
only that compressor which will provide your tool with the best possible efficiency and strength.
The most essential aspect however, which you need to remember is that you need to choose
such a compressor which has the capability of generating more power that will help in proper
running of your tool and give you best results.
The types
Besides having the versatility in the capability of power the Air Compressors are also different
when it comes to their positioning. On basis of their handling and positioning, they can be broadly
divided in to two parts, the horizontal compressors and the vertical compressors. Both have their
own pros and cons and also the workings of both the compressors are entirely different from each
other. However, the style of compressor you choose entirely depends on the type of equipment or
tool that you are using and the results you wish to attain.

POWER CONVERSION ENHANCES THE PERFORMANCE OF
YOUR ENGINE
------------------------------------------------------------*-----*-------------------------------------------------------------Usually in machines, we use Electric Motors which help us in utilizing the amount of power
supplied. Air compressor is a device that enables us to convert the power of these electric motors
as well as diesel engines into Kinetic energy or energy possessed by a running body. We cannot
directly use the power generated by the motors or engines to accomplish a task. The power
needs to be converted first. The conversion process is carried out by compressing the air which is
eventually to be released in quick successive thrusts.
This process is applicable to a large number of tasks. The most commonly used compressors are
the Centrifugal Compressors. They are also termed as Radial Compressors. These compressors
operate at high speed to generate high pressure. There are four components of a simple
Centrifugal Compressor. They are Inlet, Impeller, Diffuser and Collector. Amongst all these, the
key component is the Impeller. It is basically the set of rotating Blades that raises the energy of
the working gas.
The three major classification of Air Compressor:

6. This type of Air compressor is used in case of Gas turbines, pipeline compressors of Natural gas,
Auto-motive engines and Diesel-engine turbo chargers, oil refineries and also in Air conditioners
as well as in refrigerators. Hence, it has a large amount of importance in various sectors.
Another important classification of Air Compressor is the Rotary Screw Compressor. It follows a
positive displacement mechanism and is commonly used in place of piston compressors. Usually
these compressors are compact and run quite smoothly without much of vibration. Generally,
they are used operate high-power air tools or in large industrial unit. Recently, surveys have
shown that this type of Air compressor is vitally used in treatment of Municipal waste-water.
The third major type of Air compressor is the Turbo Compressor which is also known as the Axial
Compressor. It is a pressure producing machine which produces a continuous flow of
compressed gas at a decreasing rate. These machines are highly efficient but at the same time
complex and expensive as compared to other Compressors such as the Centrifugal ones. The
Axial Compressor is used in High-speed ship engines, Jet Engines, and small scale powerstations.
The Compressed Air efficiently drives the Air Tools
Now after the air is compressed by the Compressors, it helps the Air-tools to perform. The Air
tools are also known as pneumatic tools. Also there are Air-tools that run with the help of
compressed carbon dioxide which is supplied through the gas cylinders. The Air tools are much
safer and cheaper than the electric tools. They have an efficient configuration and the work
performance does not depend upon the size. A petty looking Air tool can perform large tasks.
RPM, Air Pressure, Air Consumption and Horse power are a few technical terms which you need
to feed in your brain to meet the job requirements.
Air-tools and Air compressors are duly inter-related and together help in the better performance of
a machine. In case of Engines, Jets and Ships it is very important to have an efficient set of tools.
Similarly Compressor pumps are necessary as well. Oil-lubed and oil-less are the two types of
pumps available. The oil-less pumps are however more efficient than the oil-lubed ones and the
disposable air tools are however cheaper than the Industrial grade ones.
