working on your house or in your shop, this guide offers valuable tips
and pointers on light to heavy-duty compressors, along with answers to
all the questions you may have about buying and using an air compressor.
Compressor + Air Tools Advantages:
" Air tools
are more powerful than traditional electric tools
" Air tools deliver higher torque and higher RPM to help get the
job done quickly
" Air tools are versatile and easily interchangeable
" Air tools are a safe alternative to other sources
power tools can dramatically decrease the amount of time spent on a project.Many
homeowners will use smaller, portable units (either hand-carried or wheeled)
that move easily from the garage to the house, yard or roof. Common air
tools, such as brad nailers, reversible drills, and impactwrenches, require
about 0-5 CFM(Cubic feet per minute-units in which air flow is measured).
It's important to know if the compressor you purchase will drive the air
tool you'll need for your project. For example, smaller air nailers, run
on 2-5 CFM at 70 to 90 PSI, while larger shears, sanders, and polishers
require up to 10 or more CFM and 100 to 120 PSI.
compressors used for business/professionalapplications are often classified
"industrial grade." They're packed with features that let you
take on more demanding jobs with more horsepower, more CFM, more PSI and
more (longer) run times. Though some industrial-grade compressors are
portable, many are stationary units with large-capacity, ASME certified
air tanks (up to 120 gallons), greater HP, more CFM air volume and faster
recovery time to run a wide variety of air tools for as long as you need
them to do the job.
do I determine my CFM Requirements?
The chart below
includes some common air tools and their average CFM measurements. Reference
this chart to determine what continuous CFM rating is required of your
air compressor. Air tools are often rated as "Average CFM."
"Average CFM" is typically based on a 25% duty cycle (15 seconds
out of a min.). This sometimes creates a problem with tools that are used
on a continuous basis (ex. Orbital sanders, die grinders, etc.) Nailers
and impact wrenches typically don't have the same problem since by their
nature are used more intermittently. If you plan on using an air tool
on a continuous basis, it is a good idea to multiply the "Average
CFM" x 4 to get a continuous CFM rating for the tool.
