Air-gas flue pipe DN110/160, 250mm, white, push-fit, for room-air-dependent operation 2651546

Air-gas flue pipe DN110/160, 250 mm, white, push-fit

This pipe is designed for ventilation and flue gas systems supplied by heating devices operating on the principle of room-dependent air – i.e., those that draw oxygen from the interior of the room rather than from outside. Therefore, it does not require a separate pipe for supplying external air – its function is to simultaneously exhaust flue gases and supply fresh air to the burner through a double-walled construction.

The construction consists of two concentric pipes: the inner pipe with a diameter of 110 mm exhausts flue gases, while the outer pipe with a diameter of 160 mm supplies combustion air. Both pipes are made of white polypropylene, resistant to the corrosive effects of flue gases and moisture. The push-fit connection allows for quick and airtight installation without additional fastening elements – simply insert one pipe into the other and secure it with clips or straps.

The 250 mm length makes it an ideal connecting element – e.g., between the device outlet and a vertical pipe or at a wall penetration. It requires no special tools for installation, which facilitates the installer's work and shortens the implementation time.

All materials meet the requirements for plastic systems in gas and heating installations. The pipe is not suitable for devices operating on the principle of room-independent air – other solutions are required for such systems.

Why does it work?

• The push-fit connection eliminates the risk of leaks when installed correctly.
• The white color facilitates identification and inspection.
• Polypropylene does not corrode – it lasts longer than metal pipes in humid or aggressive environments.
• Compatible with the operating type of devices that do not have their own external ventilation.
