What it is
The Discal Slim Automatic Air Separator 22mm is an Altecnic air separation device for use in heating and boiler systems. It removes entrained air and microbubbles from circulating system water, helping to maintain stable flow and reduce air-related noise. The slim body format allows installation where a standard separator would be too bulky.
Signs this part needs replacing
- Radiators require frequent bleeding despite no obvious system leaks
- Persistent gurgling or rushing water noise through pipework and the pump
- Pump cavitation noise or erratic circulation
- Cold spots at radiators caused by trapped air pockets
- Visible corrosion or sludge build-up around the separator body or tappings
Before you order
- Confirm the system pipework at the intended installation point is 22mm
- Check available clearance for the slim body and any surrounding fittings
- Verify the installation position and flow direction suit the unit before isolating
- Have the system drained or isolated ahead of fitting
