Flamco - 25 Ltr - Airfix P Expansion Vessel - 4 BarBuilt for sealed LPHW/CHW systems, this Airfix Expansion Vessel delivers reliable performance with a tidy, installer'friendly form.
For use in potable water, or fresh-water installations.
The Airfix D expansion vessels operate in such a way that the water flows right through and they are continuously flushed with fresh water from the mains.
This prevents tepid, stagnant water from collecting in the vessel in which bacterial growth could occur.
Therefore, users can be assured of high quality potable water.
Applying an Airfix D expansion vessel to a water heater prevents the opening of the safety group or safety valve each time the potable water is heated.
Engineered for day'to'day plantroom demands, it helps maintain stable operation, protects equipment, and simplifies maintenance.
- Reliable absorption of system expansion
- Factory pre-charge for quick commissioning
- Durable diaphragm construction
Pair with suitable isolation, safety devices and treatment to meet site requirements and best practice.

Vessels
Vessels are key to keeping water and heating systems safe, reliable, and running efficiently. They help manage pressure, protect components, and make sure everything works smoothly day after day. At Pumpify, we offer vessels from top manufacturers like Flamco, Mikrofill, Stuart Turner, and Zilmet, so you can pick the right option with confidence.
From classic pressure and expansion vessels that balance system pressure to smart heating vessels that adjust automatically, there’s a solution for every setup. Maybe a flow-through vessel to keep water moving and prevent stagnation is what you need, or a potable water vessel for safe drinking water storage and regulation suits your project better.
With Pumpify, it’s easy to find the right vessel, helping your projects run smoothly and efficiently, every time.
