The ELBI AFV 300-16 is a robust vertical accumulator (expansion) vessel engineered for booster pump systems, pressure stabilization and water-hammer protection in commercial and industrial water installations. Designed as a 300‑litre vertical pressure vessel with a 16 bar maximum rating, this tank reduces pump cycling, sustains system pressure during demand peaks and improves overall pump life.

Key features

• Capacity: 300 litres — ideal for medium-to-large booster sets and storage buffering.
• Maximum pressure: 16 bar (suitable for high-pressure systems).
• Replaceable EPDM bladder / membrane — separates water from metal and supports potable water applications where specified. ([pumpsalesdirect.co.uk](https://www.pumpsalesdirect.co.uk/elbi-afv-300-litre-vertical-accumulator-pressure-vessel-300-ltr-16-bar.html?utm_source=chatgpt.com),
• Epoxy/solvent-based protective coating for long-term corrosion resistance and external durability.
• Typical use cases: pressure boosting, pump set accumulator, surge suppression, HVAC hydronic systems and irrigation booster stations.

Technical notes & installation

The AFV series features standardized male BSP connections (main and auxiliary ports) and compact vertical footprint for easy integration into pump skids and vertical plant rooms. Typical dimensions and connection details for the AFV 300/16 are in manufacturer literature (approx. D ~660 mm, H ~1,290 mm with main connection 1¼"). Follow local codes and manufacturer instructions for pre-charge, mounting and service intervals.
