Product description

Caleffi ROBOCAL Automatic Air Vent, 40 mm, 1/2 inch – 115 °C – 502640

Caleffi ROBOCAL Automatic Air Vent, 40 mm, 1/2 inch – 115 °C – 502640 is an air vent that helps automatically discharge air that builds up in closed-loop heating systems. During water filling, maintenance, or water loss in heating systems, air can accumulate inside pipes and radiators. Air remaining in the system can impede the healthy circulation of hot water, causing some areas to not heat sufficiently.

In such situations, an **automatic air vent** helps expel accumulated air from the system without any user intervention, contributing to more efficient system operation.

Why Does Air Form in Heating Systems?

In closed-loop central heating systems, air can enter the system when it is filled with water or when the water level drops for any reason. This air collects at high points within the system and at the upper sections of radiators.

Air trapped in radiators can prevent hot water from reaching the entire radiator surface. As a result, some sections of the radiator may remain cold, or uneven heating may occur throughout the system.

For cast iron and panel radiators, manual air vents are typically used to bleed this air. However, especially in multi-story buildings, automatic air vents are preferred to continuously bleed air that forms at the high points of the system.

Where Is the Caleffi ROBOCAL Automatic Air Vent Used?

The Caleffi ROBOCAL 502640 automatic air vent can be used at high points in central heating and closed-loop heating systems where air may accumulate.

In apartment buildings, villas, workplaces, and central heating systems of various scales, installing an automatic air vent at the highest points of the system helps ensure that air forming within the system is regularly discharged.

In particular, it is recommended to use an automatic air vent at the highest point of each riser line in multi-story buildings. These points are usually located in the attic or upper levels of the system.

In domestic heating systems, depending on the system layout, the highest radiator, towel rail, or a suitable system point can be considered for automatic air vent installation.
