The ELBI AFV300 is a vertical accumulator (bladder) tank designed for boosting and stabilizing water pressure in commercial and residential systems. This 300‑litre vertical pressure vessel from ELBI features a replaceable bladder and robust coated shell for long service life, making it ideal for potable water installations, pump systems, and pressure‑boosting applications.

Key performance features include a 300 L capacity, a replaceable EPDM membrane suitable for potable water, and construction with long‑lasting epoxy coating. Typical operating temperature range and material details support both domestic and light industrial use. These design choices prioritize hygiene (potable water compatibility), reduced pump cycling, and reliable pressure retention.

Pressure ratings vary by sub‑model: ELBI AFV units are commonly offered in versions rated up to 10 bar and in higher‑pressure 16 bar variants depending on the specific AFV designation and market. Check the exact model code when specifying for high‑pressure systems. This product is sold under part number 022‑620 in several supplier catalogs.

Typical connections and dimensions for the AFV300 family include a main inlet of 1¼" with an auxiliary ¾" connection (aux often requires blanking/valving), and approximate footprint D ≈ 650 mm with height around 1.2–1.27 m. The replaceable bladder design separates water from metal components to reduce corrosion and simplify maintenance. These features make the AFV300 suitable for pump stations, pressure boosting, rainwater harvesting systems, and potable water buffering.
