Basics of Air Compressors
Air compressors function just as
their name implies - they compress air. This not only
provides a means to inflate tires (bicycle, vehicles, etc.),
water rafts and dinghies, but also provide an energy source
to power a variety of tools (wrenches, staple guns, nail
guns, etc.). Compressors also come in an assortment of types
from those designed for heavy-duty industrial use to the
compact 12 volt air compressors.
12 volt units are commonly used for domestic as well as
lightweight jobs. These tend to be portable air compressors
as they can be easily taken anywhere. Some units can even be
used outdoors away from any power source. This is a popular
option amongst many outdoor enthusiasts and all-terrain
enthusiasts who might require the energy from high-pressured
air to work their outdoor equipment. Many of these units
have been designed to be powered-up from the cigarette
lighter socket of a vehicle and can be used to vary the tire
pressure of a vehicle, off-road bike or bicycle to suit the
varying terrain conditions. Water rafts or dinghies can also
be ported in your vehicle and easily inflated in this way
when you arrive at your destination.
Air compressors come in two main types - electric run
compressors and gas air compressor. The latter does not
necessarily require an electrical source and is more easily
transported from location to location or used on jobs
outdoors. Before you invest in an air compressor, it
important to determine the level of use you intend to put
your compressor to. This will help you determine the
pressure (PSI or pound per square inch) and tank size that
will be best suited for your needs. Contrary to popular
belief, it is the size of the tank in a unit that determines
how long that unit can run for. If you intend to run two
machines at the same time with your compressor unit, you
should consider getting yourself a unit with a larger tank
size. Another important
consideration to make when looking for a suitable compressor
is the CFM or cubic foot per minute of a unit. Every tool
will have it's own CFM output and a device with a lager tank
size will generally have a higher CFM. A typical
recommendation for any given unit is one that has a CFM
capacity of 25% more than what you need. If you get a unit
that is of a lower capacity than your utilization, if may
reduce the lifespan of your air compressor.
You may be given the option of choosing between an oil
lubricated and an oil-free compressor. An oil lubricated
unit needs to be serviced regularly however this gives it a
longer life-span and maintains an optimal performance
rating. If you're concerned about the noise of your machine,
there are certain brands that offer quieter machines.
Unfortunately, these compressors tend to run on lower speed
motors. This 'minor' detail, however, might not be too much
of a drawback if you are planning on using your compressor
in the confines of your home.
Finally, the safety standards of your air compressor should
be the most important consideration in the purchase of a
unit. Make sure that the unit you buy is officially
certified safe and that its air compressor parts are in
full-working condition. Non-certified units with faulty
parts can create hazardous working environments as well as
increase the chances of accidents and even explosions
occurring.
