Compressed air filters tested for indirect food contact
Donaldson Filtration Deutschland, Haan, Germany, reports that it is now able to ensure greater safety in the application of compressed air used in the food and beverage industry. The Ultra-Filter DF series of compressed air filters for volume flow rates from 35 to 1100m³/h, was tested for indirect food contact, and under the applied testing conditions fulfilled the requirements of Section 31 (1) of the German Food and Feed Code (LFGB), as well as Article 3 of the (EC) Regulation No 1935/2004. The tests relate to materials, such as housing, filter media, seals and surface coatings.
This means that for the first time compressed air filters are available to manufacturers and operators of equipment for contamination-free food processing and beverage production. The development of the UltraPleat® filter medium in 2013 was a major step towards lowering the differential pressure, which is crucial for reduction in the energy requirement, by up to an additional 50%. This filtration technology uses specially structured coated high-tech fibres, which are processed into a pleated filter medium with high filtration efficiency for liquid particles and a high absorption capacity for solid particles. Donaldson’s head office is in Bloomington, MN. www.donaldson.com
