The Flamco Airfix P-H pressure expansion vessel is designed for potable water systems, typically for domestic waterworks and closed installations, where it helps to equalise pressure fluctuations. This protects pipework and fittings and contributes to more stable operation. The vessel is charged with nitrogen to maintain the pre-charge pressure for longer and is factory-tested prior to dispatch. The horizontal (P-H) design allows easy installation where a laid-down mounting position is required.
