2. PRESENT TECHNOLOGY AND USE OF HVAC OFFICES SUPERMARKETS PRODUCTION COMPANIES SWIMING POOLS AND SPORT HALLS HOSPITALSHOTELSAIRPORTS HVAC

3. WHY USE NANOFIBRES? Compact filters using the Nanofibres having all the best factors together: Permeability (small pressure drop) The best filtering efficiency Very small thickness of the layer High porosity Low basis weight not increase filter media weight Small pore size High specific surface area Submicron particles capture

4. NEW TECHNOLOGY USING NANOFIBER Schematic of filtering material based on Nanosolution Spunbond Engineered polymeric support providing the stiffness, mechanical strenght and pleat ability for nanofiber layer Active nanofibrous filtering layer with narrow pore size suitable for submicron filtration Schematic of polymeric nanofiber layer on support layer

5. COMPARSION OF PRESENT AND NEW TECHNOLOGY Filtering medium from Nanofibers magnified 600x – filtration class U17 Filtering medium from Nanofibers magnified 5000x Filtering medium from PA6 magnified 500x – filtration class G4 – G5 Filtering medium from PA6 magnified 2000x

6. COMPARSION OF PRESENT AND NEW TECHNOLOGY Current solutionNew design with Nanosolution - Special folded filtering material greatest active filtering surface in small space. Higher efficiency and lower pressure drop - There will be only main filter, no more need for pre-filter - Replacement of pocket filters thanks to much greater active filteration surface, lower pressure drop, and much higher efficiency H12 – U17 F6 – F9

7. BENEFITS OF NANOSOLUTION IN HVAC UNITS High filtration efficiency acc. to the MERV 15 and higher ( 90% efficient at capturing 0,3 – 1.0 micron particles). Longer filter lifetime Lower pressure drop over the filter life and less overall system energy cost Operation savings Possibility of utilisation in existing or new HVAC systems
