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.
