Altecnic Discal Automatic Air Separator 22mm Without Drain 551002

The Discal Automatic Air Separator is an Altecnic component designed to remove entrained air and microbubbles from the water circulating in a heating system. Fitted on 22mm pipework, this version has no drain facility. It sits within the Altecnic air separation range and is used on boiler and heating circuits.

• Persistent gurgling, hissing or rushing noises from the pipework or near the separator, indicating air is no longer being released.
• Cold spots or uneven heat output at radiators, suggesting air remains trapped in the circuit.
• Water weeping or staining around the separator body, cap or connections.
• Repeated need to bleed radiators shortly after they have been vented.
• Corrosion debris or sludge visible at the separator, restricting internal separation.

• Confirm the pipework at the installation point is 22mm, as this unit is sized for 22mm connections.
• Check whether a drain facility is required at this position, since this version is supplied without a drain.
• Confirm the existing separator is an Altecnic air separation unit and that the replacement is intended for the same location on the circuit.
• Isolate and drain down the relevant section of the system before removal of the old separator.
