Flamco - 8 Ltr - Airfix P Expansion Vessel - Potable Water - OBSOLETE

The Flamco - 8 Ltr - Airfix P Expansion Vessel - Potable Water is a pressure vessel designed to support pressure stability within the system and reduce rapid cycling.

It is built to help protect connected equipment and smooth system operation while giving installers and end users a practical, dependable solution for the application.

Built for sealed potable hot and chilled water systems in domestic and commercial settings, these Potable Water Expansion Vessels stabilise pressure by absorbing thermal expansion for safe, reliable operation.

A nitrogen pre-charge helps retain set pressure longer, while a single threaded steel connection with plastic insert provides a durable, non-flow-through design. Suitable for central heating, cooling and tap water applications (not for solar collector circuits).

• Nitrogen gas filling for longer pre-charge retention
• Single threaded steel connection with plastic insert (no flow-through)
• Potable use supports domestic hot/chilled water
• Heating & cooling compatible for sealed systems

Designed for long service life with broad operating limits and glycol tolerance for demanding installations.
