If there are emissions from your filter, this can be caused by leaks in just one bag. Therefore, examine for possible leaks before replacing expensive spare parts. By adding fluorescent leakage detection powder that lights up in ultraviolet light, you can easily locate leaks using with a UV lamp and then replace the filter bag in question.
At konfAir, we offer 2 different UV lamps and several colours of fluorescent powder, packed in easy-to-handle 4 kg buckets. The powder has with its very fine particle sizes ( 4 μm ) a very high performance level due to high viscosity, low dust and is stable in temperatures up to 300 degrees.
