The maintenance manager of this Oriented Strand Board (OSB) plant was skeptical of trying a new filter — despite the fact that his crew had to changeout filter bags monthly and perform extra pulse-cleaning cycles during downtime to try to extend filter life. 

He couldn’t believe any filter material was up the challenge of the sticky waxes & resins produced during the manufacture of OSB. He finally decided to test Dura-Life™ filter bags in one of his Donaldson® Torit® RFW baghouse dust collectors, as shown at left. 

Is he happy that he did? Yes! Now, the crew services the bags only during scheduled maintenance time, about every 3 months. Even better, they no longer need downtime cleaning to reduce pressure drop. The Dura-Life filters are running at a lower pressure drop with less pulsing, saving both fan energy and reducing compressed air costs.

“That the Dura-Life filter bags lasted twice as long and downtime pulsing was not required are strong factors for me. I now plan to use Dura-Life bags in all of our dust collectors.”
