Flamco expansion vessels for drinking water systems

The diaphragm pressure expansion vessels are suitable for drinking-water heating and pressure boosting systems with flow-through technology. Due to their special design, the Airfix expansion vessels with flow-through construction are constantly flushed with fresh tap water from the mains. This prevents tepid, stagnant water collecting in the vessel and so unwanted bacteria formation in the water circuit. This ensures high quality drinking water.

The expansion vessels are approved according to DIN-DVGW and EU Pressure Equipment Directive 97/23/EU, comply with the KTW-C guideline and fulfill the requirements of DIN 4807/5.
