Round polypropylene air ducts

Polypropylene ducts is resistant to aggressive vapor environments and temperature extremes. Polypropylene is a light material, the load on the supports of the ventilation system is minimal. The air ducts are subject to corrosion during the entire period of operation, reaching 50 years of age. The use of polypropylene ducts ensures complete tightness of the ventilation system, excluding a leakage of aggressive media. In the manufacture of ducts using conventional polypropylene and modifications of this material with such properties as high resistance to fire and superior conductivity.
