Ventiflex VTX Flexible Duct

The VENTIFLEX VTX ducts are designed for the construction of mechanical ventilation systems i.e. distribution systems.
Due to the enlarged inner diameter, they are able to pass the following amounts of air (while maintaining a flow rate of 3 m/s):
– VTX-DN75 – 40 m3/h,
– VTX-DN90 – 55 m3/h.

The VENTIFLEX VTX ducts have the Hygienic Certificate of the National Institute of Hygiene (PZH), which confirms that they meet the hygiene requirements for use.
