Flamco

Designed for mains-fed potable and fresh water systems, the Flamco Airfix D Expansion Vessel is a full flow-through potable vessel that prevents stagnation and nuisance safety-valve discharge by absorbing thermal expansion.

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.

A synthetic flow-through insert and the supplied brass flow-dividing T-piece (3 R ¾") divert all connection flow through the vessel, continuously flushing it to inhibit bacterial growth. The butyl diaphragm is taste/odour neutral, while corrosion-resistant internal coatings protect both water and nitrogen sides. Each vessel is factory tested, nitrogen pre-charged for longer pre-pressure retention, and internationally approved.

• Flow-through operation constant refresh prevents tepid, stagnant water
• Protects safety devices reduces safety-valve lift and leakage risk
• Potable-safe butyl diaphragm adds no colour, odour or taste
• Efficient & hygienic no waste of potable water during operation
• Durability vessel halves coated before assembly; clamp ring protected
• Nitrogen pre-charge for better long-term pressure stability
• Includes: special brass flow-dividing T-piece (3 R ¾")
• Optional: Airfixcontrol for quick annual pre-charge checks

Engineered for potable and general water services, the Flamco Airfix D-E Expansion Vessel uses a full flow-through construction to prevent stagnation and support hygienic, high-quality water delivery.

A replaceable butyl bladder (DIN 4807/5) is formulated to add no colour, odour or taste, while a coated two-way system connection ensures complete vessel flow-through with low pressure drop. The Airfix D-E includes a pressure gauge with blow-back protection, nitrogen pre-charge for long pre-pressure retention, and an anti-oxidation coating on the inside of the connection flange.

• Full flow-through design to minimise bacterial growth
• Potable-safe bladder — no impact on taste, colour or odour
• Nitrogen pre-charge for longer pressure stability
• Coated flange & two-way connection to prevent oxidation and ensure flushing
