Brand: ELBI. A compact, coated vertical accumulator/pressure vessel designed for boosting and stabilizing water pressure in domestic and light commercial pumping systems. This model is a 24 litre (approx. 25 L listed by some distributors) vertical diaphragm accumulator rated for up to 16 bar maximum working pressure.

The AFV 24-16 uses a replaceable EPDM diaphragm/bladder to separate water from the air chamber, ensuring potable water compatibility and long service life. Typical applications include booster sets, pressure stabilization for low-supply mains, reducing pump cycling (anti-hunting), and small-scale hydronic or potable water systems.

• Capacity: 24 litres (nominal).
• Maximum pressure: 16 bar; hydrostatic test pressure commonly specified around 22.9 bar in technical datasheets.
• Precharge: factory precharge typically ~2.5 bar (adjustable on-site).
• Connection: 1" main connection (check local BSP/NPT variant).
• Materials & finish: mild steel body with durable epoxy/powder coating for corrosion resistance; replaceable EPDM bladder.
• Operating temperature range: approximately -10°C to +99°C.

Built for reliable pressure stabilization and reduced pump cycling, the ELBI AFV 24-16 (SKU 022-631) is a practical, serviceable choice for installers seeking a compact vertical accumulator with a replaceable bladder and robust coating for corrosion protection. For installation, verify precharge, inlet connection type, and local pressure requirements to ensure optimal performance.
