Protan Ventiflex Duo
Protan Ventiflex Duo is a concept that has been developed to transport air through narrow passages or in tunnels with limited headroom without compromising the air flow.
For narrow passages
The idea is simply to substitute the main duct, with two smaller diameter ducts, through a transition piece, not compromising on air volume and other capabilities of the designed ventilation system.
Less energy consumption
Protan Ventiflex Duo has a larger cross-section than other similar systems, which means lower energy consumption for the same installation height and fan output. It also delivers more air to the face with the same fan output.
Two independent ducts
The two standard ducts are independent, and are utilizing all the standard coupling systems. The advantage is obvious, the duo-duct has no conceptual limitations for the total duct-length installation.
In order to ensure efficient delivery of our best-selling ventilation systems, the products we offer are divided into three categories.
