FL-Airfix P18
Flamco - 18 Ltr - Airfix P Expansion Vessel - Potable Water - 10 barBuilt 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.

Vessels
Pressure vessels and expansion vessels play a big role in keeping systems safe and balanced. Expansion vessels are commonly used in heating and hot water setups, where they absorb the natural rise in water volume as it heats. This keeps pressure under control, reduces the chance of leaks, and protects boilers, pumps, and pipework from damage.
Pressure vessels are found in pressurised water systems, including potable water supplies. By storing water under pressure, they cut down on pump cycling, extend system life, and deliver a steadier, more reliable flow.
At Pumpify, you’ll find both pressure and expansion vessels in a variety of sizes and specifications, so it’s simple to choose the right fit for your project.
