You May Not See the Contaminant Residues In Ductwork

When asked about his pitching, Walter Johnson, the legendary Major League Baseball pitcher for the Washington Senators is credited with the saying . . . “You can’t hit what you can’t see”. And I’m sure you’ve heard the more profound . . . “Just because you can’t see it, doesn’t mean it’s not there”.

Whether you’re talking baseball or just plain old everyday life, there’s truth in both quotes.   I don’t know about you, but I can’t see air . . . but I know it’s there.

What we don’t see can be just as important as what we do see.  It depends on our perspective.

Take the industrial environment for example.

Manufacturing typically creates all kinds of contaminants whether it’s dust, smoke, mists, or any number of different particulates.  These contaminants are removed from the manufacturing facility through an exhaust system. Ideally, these contaminants are filtered from the exhaust air before it is released back into the atmosphere.  But residues from the manufacturing can, over time, buildup in the exhaust ductwork itself.  This buildup can prevent airflow, can possibly be a fire hazard, and can potentially be released into the atmosphere.

Because it is in the ductwork, it’s hidden.  And you probably don’t see it.  But it can be there. Regular cleaning to remove the residual buildup should be done.

It may not be an easy job . . . which is why we hope you call us.
