The ELBI AFH100 horizontal pressure vessel (accumulator / expansion tank) is a 100 L bladder-type hydrophore designed to stabilize water pressure in pump systems and reduce pump cycling for residential and light industrial applications. It is built for potable water and general water-boost systems where consistent pressure and reliable pump operation are required. /p>

Key specifications

• Capacity: 100 L (horizontal layout)
• Maximum working pressure: 10 bar
• Recommended working range and max temp: -10 °C to +99 °C
• Connection (inlet): 1"
• Factory pre-charge air pressure: typically ~1.5 bar
• Internal bladder: replaceable EPDM diaphragm
• Finish: epoxy powder-coated steel for long-term corrosion protection

These technical features make the AFH100 suitable for hydrophore and booster sets, pressure boosting for domestic water, irrigation tie-ins, and closed-loop systems where separation of water and air (bladder design) protects metal parts and preserves water quality.

Benefits & installation notes

Installing the AFH100 accumulator reduces pump start/stop cycles (improving pump lifetime), smooths pressure fluctuations, and provides short-term reserve water to meet peak demand. The tank is normally supplied factory-precharged; final adjustment of pre-charge should be performed on-site to match the system pressure switch setpoint. Follow standard plumbing best practices and install a safety valve or isolation fittings as required.
