During the operational life of installed filter media in a dust collector, it is frequently found that levels of emission have risen to an unacceptable level, yet often the majority of filters within the installation are known to be intact and in good condition. Invariably, these sporadic failures are as a result of abrasion of the filter elements against each other or the adjacent walls of the equipment, or from flexing of the filter media against the support cage.
Other causes can be localised heat or sparks, the misalignment or progressive loosening of filters against seals, or frequently the accidental introduction of sharp objects into the system.
It is often impossible to locate or identify the failed unit(s), thus conventionally requiring a complete, but unnecessary filter change to restore the original level of performance.
To overcome this problem, and to avoid the potential expense of a major refurbishment, Micronair Engineering have the facility for locating each individual failure by the injection of a UV reactive fluorescent dye - "REACTOLITE®" - into the system.
