Automatic air vent, simple, nickel-plated, FLEXVENT 1/2 inch, 10 bar, with shut-off valve 27742

Automatic air vent – reliable air removal from the system

This nickel-plated Flexvent automatic air vent with a diameter of 1/2 inch is key to the efficient operation of heating, cooling and air conditioning systems. Designed for both professional installers and end-users, it effectively removes air, protecting the installation from corrosion and reduced performance. A solid construction made of nickel-plated brass guarantees long-lasting reliability even in harsh conditions.

Design and application

The Flexvent air vent is distinguished by its compact dimensions, making it easy to install even in tight spaces. Made of brass with a nickel coating, it is resistant to corrosion and mechanical damage. The shut-off valve facilitates servicing and replacement of the device without the need to drain the entire installation. Designed for use in central heating installations, heat pumps, cooling systems and air conditioning systems. The possibility of using with glycol (up to 50% concentration) expands its range of applications.

Advantages and benefits

• Automatic operation: does not require manual operation, which translates into saving time and operating costs.
• Shut-off valve: enables quick installation, disassembly and servicing without the need to shut down the entire system.
• Durable construction: brass body with nickel-plated coating provides corrosion resistance and longevity.
• Installation protection: removing air prevents corrosion, pump cavitation and reduced heating or cooling performance.
• Wide application: ideal for CH installations, heat pumps, cooling systems and air conditioning systems, as well as systems with glycol.
• High efficiency: air flow rate of 1.92 m³/h ensures effective venting of the system.
• Safety: has a leak protection, minimizing the risk of failure.

This air vent is characterized by a nominal diameter of 1/2 inch (15), a maximum working pressure of 10 bar and a maximum medium temperature of 90 °C. The housing is made of brass with a nickel-plated protective coating, and the connection diameter is 21.34 mm.

The Flexvent air vent is an investment in the trouble-free operation of your installation for years to come. Its solid construction and automatic operation ensure comfort of use and cost savings related to servicing and repairs.
