Ideal Automatic Air Vent Kit Isar/Icos 170988

Ideal Automatic Air Vent Kit for Isar/Icos systems is designed to protect and optimise central heating performance. The model 170988 uses a float-operated vent to release air that collects in the system as water circulates. When the water level is high, the float closes the vent; as the level drops, it opens to vent trapped air. This helps maintain efficient operation and supports reliable performance of compatible boilers. It is a genuine, brand-new Ideal Heating spare part, supplied with a manufacturer guarantee.

The vent is compatible with a range of Ideal boilers and is intended as a safety and efficiency component within the heating system. By removing air and preventing air locks, it supports long-term durability and manufacturer-approved protection for the system.
