The DYNAguard D Eco monitors the dust concentration behind a bag or cartridge filter. It is installed on the clean air side of the filter. It identifies if a filter is damaged, e.g. by cracks, fractures or assembly errors. This allows to replace a damaged or broken filter in time, without losing production time and without polluting the shopfloor or environment. Dust monitors are especially important in case of heavily contaminated air, recirculation into the factory, strict external emission limits or dust reusage.
