rapidly cooled, for example, if the air line leaves the compressor and then travels thru a cold
warehouse or passes between two buildings, moisture can
condense out and collect inside the
air lines. Compressed air delivery systems need to be designed to remove excess moisture
from the air and air lines. This is typically accomplished with a piece of equipment known as
a dryer. Two types – desiccant dryers and refrigerated dryers are commonly used.
Most air compressors have built in air filters designed to remove dirt and grit from incoming
air. Standard industrial grade air compressor filters typically remove all particles greater than
1 micron in diameter and are sufficient for use with all US Tax Stamping equipment.
Some compressed air systems are designed to ADD lubricant to the compressed air to reduce
the wear and improve the performance of certain types of machinery. Other air delivery
systems contain air/oil separators to remove oil from the compressed air. All US Tax
Stamping equipment is designed to operate on clean (no particles or oil); dry (no water) air
although the 12M case cutter can also accept lubricated compressed air.
All US Tax Stamping stamping machines which utilize compressed air contain their own,
integral coalescing filter bowls which are designed to remove oil, water and dirt which may
have passed thru the primary systems in the compressed air delivery system, but these
systems are intended only to remove occasional contaminants and do NOT eliminate the
need for properly filtered and dried air delivery systems.

The primary choices among compressor types are piston/reciprocating vs
rotary/screw. Among the piston compressors you will select between single and dual
head compressors and lubricated vs oil-less. Screw compressors are generally more
expensive but significantly quieter, usually less than 70 dBA at a distance of 3 feet
from the compressor (a level of sound typical on a busy downtown street) while
reciprocating compressors are often above 80 dBA (a level of sound similar to that
near a typical residential gasoline powered lawn mower.) The level of sound-output
is an important consideration and should not be overlooked. Since it is desirable to
have the compressor located near the stamping equipment it should be noted that it is
difficult to converse and sometimes distracting to work in the particularly noisy
environment surrounding a reciprocating compressor. Ideally the compressor can be
moved around a corner, behind a wall, or one floor above or below the area where
operators will be working – but keep in mind that it is also important to try to have
the compressor, delivery lines and stamping equipment all at nearly the same
temperature as described elsewhere in this document. Screw compressors have fewer
wearing components and generally require a simpler maintenance schedule. Screw
compressors also deliver cleaner air with no oil in the air. This generally extends the
life of the stamping equipment by reducing buildup inside of cylinders and air valves.
If a reciprocating compressor is used it is important to select a high quality oil-
