The Flamco Airfix P-H pressure expansion vessel for potable water is designed to stabilise pressure and reduce pressure surges in potable water distribution systems, e.g. domestic waterworks and booster sets. The horizontal design makes installation easier where height is limited or where a “horizontal” mounting position is required. The vessel is charged with nitrogen to maintain the pre-charge pressure for longer and is fitted with a replaceable diaphragm. The construction is designed for reliable, hygienic operation in potable water applications and meets the requirements of the relevant Pressure Equipment Directive.

Main features

• For potable water systems (domestic waterworks, booster sets, distribution pipework)
• Horizontal design, side connection
• Nitrogen charge for more stable pre-charge over time
• Replaceable diaphragm (serviceable design)
• Operating temperature suitable for hot water in installations
