CAMTU Compressed Air Microbial Test Unit (Parker Balston)

The CAMTU compressed air microbial test unit identifies sources of contamination in compressed air. Compressed air is used in a broad range of applications in the food processing industry, such as mixing of ingredients, cutting, sparging, drying of product, transporting/propelling product through processing systems and packaging of final product. In many of these applications, compressed air is in direct contact or indirect contact with food product. The impurities in the compressed air may contaminate the food product which can result in change of color and taste, reduced shelf life, in addition to exposure to bacteria and other micro-organisms, can result in product recalls.

How to use the CAMTU microbial test unit.
To obtain a sample, simply plug the connection tubing into the sample point on the compressed air system, insert a specially designed petri dish into the CAMTU, close the CAMTU, open the shutoff valve and expose the agar for 20 seconds. After exposure simply place the petri dish in an incubator for 48-hours or in a controlled environment of at least 68°F and observe for colony forming units (CFUs). Handles up to 40 PSI.
