## Summary description

Automatic air vent Hydroland for central heating (C.O.) with DN25 connection and left-side port. Designed to remove trapped air from heating circuits, the device ensures stable circulation and reduces noise and corrosion. Suitable for installation in boilers, manifolds and piping systems where DN25 and left orientation are required.

## Long description

Hydroland automatic air vent for central heating DN25 with left connection is a mechanical component designed to remove trapped air from closed heating circuits. The device ensures stable circulation of heating medium, reduces noise caused by air pockets and helps prevent corrosion by eliminating oxygen-rich air from radiators, boilers and piping. Its DN25 threaded connection and left-side orientation make it suitable for installations where that configuration is required, such as certain manifold layouts and boiler ports.
Advantages
The Hydroland automatic air vent operates without external power and continuously vents air as it accumulates, maintaining consistent hydraulic performance. Constructed for compatibility with standard DN25 pipework, it provides a compact solution that minimizes manual bleeding and maintenance. The left connection orientation simplifies integration into systems that route piping or manifolds in a specific direction, and the mechanism reduces noise and the risk of cavitation in pumps.
Suitable for
 Automatic venting of radiators and convectors in closed central heating systems
 Installation on heating manifolds with left-side port requirements
 Use on boiler ports and sections of piping with DN25 connection
 Replacement of manual air vents to reduce maintenance intervals
Key specifications
 Connection size: DN25 threaded connection compatible with DN25 pipe fittings
 Orientation: left-side discharge port for alignment with specific installations
 Function: automatic mechanical air release for closed heating circuits
 Application: central heating systems including boilers, manifolds and radiators
 Operating principle: passive float-operated venting mechanism
How to use
Install the automatic air vent at a high point in the heating circuit or at designated venting points on manifolds and boiler ports, ensuring the left connection aligns with the system piping. Before fitting, isolate the local section, depressurize and drain if required by the installation instructions of the system. Thread the DN25 connection into the fitting using appropriate sealing material and torque compatible with the pipework. After installation, refill and pressurize the system, then observe the vent for proper operation and absence of leaks. Periodically check the vent for signs of blockage or persistent leakage and replace if the mechanism fails.
Usage recommendations
For reliable performance, install the vent at system high points where air accumulates and combine it with a routine maintenance check of the heating circuit. Use compatible DN25 fittings and avoid overtightening threads. If system water contains significant debris or chemical treatment, consider installing filtration or a dirt separator upstream to prolong vent life.
