Automatic air vent – comfort and efficiency

The ROBOCAL series air vent, equipped with a check valve, is a reliable solution for automatically removing air from central heating and air conditioning systems. Its function is to prevent noisy system operation, reduce component wear, and ensure optimal heating device performance. The forged brass construction guarantees durability and corrosion resistance, and the check valve facilitates maintenance and replacement.

Construction and application

ROBOCAL valves are characterized by a simple but effective design. The float, protected against vibrations and rotation, ensures stable operation, and the sealing element made of silicone rubber guarantees tightness. Installation on risers of the installation, at points of potential air accumulation (e.g. at air separators or manifolds) allows for effective air removal without manual intervention. The check valve is particularly useful during servicing – after unscrewing the air vent, it automatically stops the water flow, minimizing the risk of flooding.

Key features and benefits

• Automatic operation: Eliminates the need for manual venting of the installation, saving time and effort.
• Durable construction: The forged brass body provides resistance to high pressure (up to 10 bar) and temperature (up to 110°C).
• Check valve: Facilitates maintenance and replacement of the valve, preventing water leaks.
• Protected float: Ensures stable operation even in vibrating conditions.
• Wide application: Ideal for central heating and air conditioning installations with water or glycol solutions (up to 30% concentration).
• Corrosion protection: Removing air reduces the risk of corrosion of installation components, extending their lifespan.
• Energy efficiency: By removing air from the heating system, its efficiency is improved and energy consumption is reduced.

The ROBOCAL air vent is an investment in comfort and reliability of the heating system – both for professional installers and end users.
