Executive Summary
The purpose of this report is to convey the results of the compressed air quality analysis performed in Medical
Components of America’s facility in December of 2016 specifically looking for a reason for component failure in
the compressed air system.
The results from the Compressed air samples are below:

1: Methodology
Compressed air sampling device
The compressed air was sampled using the TRI air sampling device in the
photo to the right. The device is used for sampling particulate, oil mist,
and dew point.
Lab Area: The sample taken in the lab area was the sample point closest
to the compressor room after the catalytic converter unit.
Production Area: The sample from the production area was taken from
the compressed air line that was connected to a piece of production
equipment that was down for maintenance.
2: Analysis
The full results from the compressed air samples can be found at the end of the report. The dew point in the
sample report represents the dew point of the compressed air at the pressure of the sample (5-6 PSIG). The
dew point of the compressed air had to be calculated using the formula P1/P2=e1/e2 where P is compressed air
pressure and e is Saturation Vapor Pressure found from the table below.
a. Dew Point - The dew point of the compressed air was in the ISO Class 4 range. To be able to
bring the dew point to a Class greater than 4 a different drying process must be used. The most
common drying process to bring dew point to below the freezing point of water is through the use
of a regenerative desiccant dryer. With the use of a dryer with a dew point setting of -100 F the
ISO quality with respect to dew point can be brought to Class 1.

b. Oil Mist - The oil mist content of the compressed air was in the ISO Class 1 range. The oil content
of the compressed air was lower than the minimum reporting limit of 0.02 mg/m^3.
c. Particle Size - The particle size could not be determined by using TRI’s air sample. The total
particle concentration was determined to be in the low to almost non-existent range.
System Configuration:
The drawing below shows the current compressed air supply system configuration. It includes filtration, drying
equipment and a catalytic converter unit to remove oil from the compressed air system.

Damaged Components:
The photos below show some of the damaged components in the compressed air system.
Green Corrosion on brass fittings and an inline filter dryer that looks melted
Plastic fittings (two manifolds and one elbow) are cracking:

Conclusions:
The compressed air leaving the compressor room is clean, dry and has a minimum amount of oil content. The
issues with the components in the compressed air system is not due to water or oil contamination in the compressed
air system. The component failure is not due to normal compressed air contamination, but seems to be due to a
corrosive substance in the compressed air.
