Can the filter cloth get clogged?
In a typical industrial application, it is unlikely that the 2-micron filter cloth will become clogged before the breather has reached its full capacity of water. The filter cloth is a patented polyester knit with the two sides made differently. The side that is placed in the “up” position in the breather is knitted with a loose pile surface that closes to 2-micron when hit by incoming air. When air is expelled from the tank, it goes back through the filter and the knit opens back up (loose) throwing off the particles collected on the top surface. In the filter industry this is called “backflushing.” These particles flow out of the breather with the expelled air creating a self-cleaning process. In extreme situations, such as breathers being constantly covered with dust and a customer is concerned, the Ultra Clean C-Series is available with a 25-micron filter cloth.
