The ELBI AC25 (often listed as AC25 / AC25 GPM) is a compact, coated bladder accumulator designed for domestic water boost and small commercial booster systems. It reduces pump cycling (pump hunting), smooths pressure delivery for taps and fixtures, and is well suited for domestic water supply, garden irrigation and compact pressurization units.

• Capacity: ~24–25 litres (nominal 24 L working capacity).
• Bladder: Replaceable EPDM bladder—suitable for potable (sanitary) water applications.
• Working pressure: 8 bar (10 bar maximum rating on many AC25 variants).
• Connections: Typically 3/4" – 1" main connection depending on variant; compact footprint for direct pump mounting.
• Finish & Standards: Blue epoxy powder coating for corrosion resistance; CE-certified models / compliant construction and wide operating temperature (-10°C to +99°C for most AC models).

Constructed from durable steel with a food-grade, non-toxic bladder that fully separates water and air, the AC25 delivers quiet operation, low maintenance and reliable pressure stabilization for showers, faucets and irrigation lines. Its compact size and mounting options make it ideal for integration with small booster pumps and packaged pressure sets.
