Absolute filters

Absolute filters (or HEPA, High Efficiency Particulate Air filters) provide filtration efficiency greater than or equal to 99.98%. They are always used in combination with a pre-filter.

They can be used in air conditioning installations, operation theatres, clean rooms, filling spaces…. Their frame is made of aluminium, galvanized steel or stainless steel, equipped with a peripheral seal. The filter media is made of fiberglass or Teflon (PTFE). The filters are individually factory tested (starting with classification H13). After installation, the filter is once again tested by an independent company, to guarantee a maximum filtration quality.
