Here are Features to specifically look for when choosing an Air Compressor
- ASME (American Society of Mechanical Engineers) tank
- Belt-driven Air
Compressor — Belt-driven compressors generally have
a longer life, with less vibration and heat transferring from the motor/engine
to the pump.
- Cast iron cylinder or cast iron pump sleeves — Cast iron
is typically the standard material for cylinders
- V-design cylinders -- V-design cylinders typically
run cooler that in-line cylinders. Heat is a compressor's worst enemy.
- Vertical
vs. horizontal air compressors -- Vertical compressors
usually take up less floor space than horizontal compressors. Typically,
vertical compressors
are stationary, whereas smaller horizontal compressors are better for
portable applications (such as a truck-mounted compressor).
- 100-percent Continuous Speed
operation vs. Auto Start/Stop operation -- Auto
start/stop operation has preset cut in/cut out pressures. The compressor
actually stops and turns back on as air is needed. With constant
speed operation, the
compressor runs 100-percent of the time and simply adjusts the air output.
Dual control compressors offer both auto start/stop and continuos
speed operation.
- Fully packaged unit with premounted and prewired magnetic motor start,
dual control, belt guard mounted air cooled after cooler and electric
condensate drain
- Low-oil shutdown prevents downtime and costly repairs resulting
from low oil levels
- Oil-Free (or Oil-less) compressors are virtually maintenance-free
performers for light- to general-duty applications. No need for periodic
oil changes.
How to figure out your CFM (cubic feet per minute) Requirements:
The table below shows some common air tools and their average CFM
measurements. Use this table to determine what continuous CFM rating
is required of your air compressor. Air tools are often rated as "Average
CFM." "Average CFM" is normally based on a 25% duty
cycle (15 seconds out of a minute). This sometimes creates a problem
with tools that are used continuously (for example, die grinders,
orbital sanders, etc). Nailers and impact wrenches usually do not have
the
same issue
since by design they are used more intermittently. If you plan on using
an air tool continuously, it's a important to multiply the "Average
CFM" by 4 to get a continuous CFM rating for the air tool.
