Colasit complete ventilation systems made of plastic for corrosive exhaust air and gases

Setting the standard for plastic construction and short delivery times

Optimum ventilation solutions

Thanks to the flow-optimised design with high energy efficiency and a long service life due to the material thickness and construction in welded design

Exhaust air systems and ventilation systems made of plastic, integrated into the overall exhaust air technology and ventilation construction


If corrosive exhaust air and gases cannot be excluded in the ventilation system, plastic components are used instead of sheet metal components. 

We supply complete systems and earth-laid ventilation pipes made of plastic with customised design, engineering and 3D planning, as well as all required components such as ducts, pipes, moulded parts, fittings, heat exchangers and plastic fans including assembly. 


Colasit provides optimised solutions in the ventilation area with regard to

  • Consultation and project management
  • Deep flow pressure losses and therefore better energy efficiency
  • Chemical resistance
  • Tightly welded design
  • Ventilation components with high strength and stability 
  • Optimised configuration of plastic fans for the complete system 
  • Short delivery times and short assembly times thanks to standardisation and pre-production of the ventilation components


At Colasit, you get everything optimised for the process from a single source:
