Advantage: Chemical resistance


The surface of the VENTAFLEX air ducts are very resistant against environmental influences

GRP is resistant against solvents, plasticisers, fuel, mineral oil, diluted acids and alkalis: moreover against the influence of exhaust gases or aggressive industrial atmoshere.
The resistance against chemicals is especially beneficial with regard to hygiene and cleaning of the air ducts: the surfaces are not affected by common industrial cleaners.


Impact of different chemicals on GRP-surface

The impact of different chemicals on the surface of the VENTAFLEX air ducts was tested in extensive tests. This is only an extract of the substance tabel – you can get information on further resistances upon request.
