HAVERHILL, Mass. -- November 4, 2013

The Filtration and Separation Division of Parker Hannifin Corporation, the
global leader in motion and control technologies, has introduced an innovative
compressed air microbial detection device which allows users to quickly test
for microbial contamination in compressed air that comes into contact with
food and food contact surfaces.

The warm, dark, moist environment inside a compressed air system provides the
perfect conditions for microbes to flourish and grow. These bacteria flow
along with the air stream and begin their journey through the compressed air
system. Introducing this type of microbial contamination to food products is
very risky and would be considered a lack of control by the facility. It is
not always apparent where the compressed air is contacting the food. Working
surfaces such as counters and conveyors are obvious and manageable contact
points. However, air is invisible, and leaves no visible trace where it
contacts the food, food contact surfaces, or the packaging.

Currently, the only devices capable of sampling compressed air systems for
microbes are expensive, cumbersome, require lengthy sample times and extensive

The Parker Balston CAMTU detection device allows food safety personnel to
quickly and easily test for contamination present in compressed air supplies
that come in direct contact with food product or food packaging/processing
equipment. The CAMTU is portable, weighing less than one pound, and is
supplied with connection tubing, shut off valve, pressure regulator, and
metering orifice.

To obtain a sample, simply plug the CAMTU into the compressed air system,
expose the petri dish for 20 seconds and then incubate the dish for 24 - 48

Testing is critical for understanding how to properly treat the compressed
air. The CAMTU will assist with identifying Hazard Analysis and Critical
Control Point (HACCP) risks. Without adequate treatment in place, an increased
risk of food product contamination exists.
