The ELBI AFV100 is a 100‑liter vertical diaphragm (bladder) pressure vessel designed for domestic and light industrial water systems. Engineered to separate water from air and protect pumps from short-cycling, this coated expansion vessel delivers reliable pressure buffering, reduced pump starts, and quieter system operation.

Key features

• Capacity: 100 L, vertical format for compact installation.
• Interchangeable food‑grade EPDM bladder to ensure potable water safety and long service life.
• Working temperature range: -10°C to +99°C, suitable for heating and sanitary applications.
• Maximum working pressure: typically up to 10 bar (check model variant for 16 bar options).
• Durable epoxy powder coated steel shell (blue finish) for corrosion resistance and outdoor use.
• Simple maintenance: replaceable diaphragm and accessible precharge valve for quick servicing.

Applications

Ideal as a pump protection accumulator, expansion vessel for closed circuits, or pressure buffer for domestic water supply, garden irrigation and booster systems. The AFV100 reduces water hammer, extends pump life, and lowers energy consumption by minimizing pump cycling—making it suitable for residential, agricultural and light commercial installations.

Installation & maintenance notes

Install vertically on a stable base near the pump or system manifold. Verify precharge pressure before commissioning (factory precharge is common), and check the bladder periodically; a replaceable bladder design simplifies repairs without draining the system. Ensure correct sizing for system flow and pump curve to optimize performance.
