Ideal Automatic Air Vent 172948

The Ideal automatic air vent, part number 172948, is a replacement air-eliminating device used on Ideal Commercial Buccaneer appliances. It sits at a high point in the system and automatically discharges air that collects there, so the water circuit stays free of trapped pockets. It is supplied as a serviceable spare for the Buccaneer range.

• Gurgling, bubbling or rushing noises from the boiler or pipework as air moves through the system.
• High points and radiators that need bleeding repeatedly, even shortly after the system has been filled.
• Water weeping or dripping from the vent body, cap or its connection.
• System pressure that drifts or fluctuates without any obvious leak elsewhere.
• Poor circulation or cold spots at the top of the system that persist after bleeding.

• Confirm the appliance model and serial number against the compatibility list; this vent is listed for Ideal Commercial Buccaneer units.
• The part has also been listed under 94918138 and 1179190, so if your manual or an old invoice quotes either number, this is the same item.
• Inspect the sealing washer on the old vent when it is removed and renew it if it is compressed or perished.
• No GC number is recorded for this part, so match on the Ideal part number and the appliance model.
