“As you know, a few years ago, our plant installed a plenum dust collector in our eastern US cement plant location. During the following three years we experimented with a variety of polyester filter bags, each with a different surface, treatment, or coating, but all with essentially the same result: average life span was 6 months and in no instance exceeded 9 months. Time after time, without exception, each set of trial bags plugged prematurely, creating high pressure differential, reduced air flow and, consequently, a precipitous drop in production.
After years of struggle, we agreed to test a set of Albarrie’s Tandem Polyester Composite bags. Today, nearly three and one half years later, that same set is still in service, providing the customer with improved production, reduced power consumption, all while maintaining 5”-6” pressure drop with no emissions. The resultant annual saving to our operations can be summed up as follows:
- Increased production/reduced power consumption$57,000.00
- Cost of Two sets of standard Polyester Filter bags$17,000.00
- Labor Saving$4,000.00
Total Annual Saving: $78,000.00
Clearly, our initial investment in Albarrie’s Tandem Polyester filter bags was paid back within six months and, more importantly, we have gleaned an additional savings of over $200,000.00 during the subsequent three years of production.
Operationally, we would be remiss not to mention that the Albarrie composite bags have withstood an impressive amount of abuse, including two major upsets during which moisture entered the collector and totally encrusted the cake on almost every bag. In both instances, airflow was reduced to near zero with a corresponding drop in production. Your bags were subsequently removed, cleaned with counter feeding brushes, returned to service and once again continued to perform well at 5”-6” pressure drop. Obviously, standard polyester bags would have blinded under the same upset conditions, so an additional two complete bag change-outs were avoided.
Albarrie, maintenance and purchasing people are not generally known for heaping lavish praise on their suppliers, but our experience with Albarrie compels us to make an exception. In a nutshell, the consistently high value of both your products and service has given us every reason to continue to rely upon Albarrie for virtually all of our filter media needs.”
