## Summary description

Omnigena VAO150 is a horizontal 150‑liter diaphragm pressure tank designed for water systems. It features a preinstalled flexible diaphragm to separate water and air, providing steady pressure, reduced pump cycling and protection for connected equipment. Suitable for domestic water supply, irrigation and booster systems where stable pressure and water reserve are needed.

## Long description

Omnigena VAO150 horizontal 150 L diaphragm pressure tank is designed for domestic and light-commercial water systems. The factory‑installed flexible diaphragm separates the water chamber from the air cushion, providing a reliable 150‑liter water reserve and helping to maintain steady system pressure. The horizontal steel shell is suitable for installation in basements, pump rooms or other confined spaces where a low-profile tank is required. The Omnigena VAO150 reduces pump cycling, protects connected pumps and fixtures, and supports irrigation, booster and household water supply applications.
Advantages
The preinstalled diaphragm prevents waterlogging and preserves the air cushion for consistent pressure delivery. With a 150 L capacity, the VAO150 offers a useful reserve that decreases pump start frequency and extends pump service life. The horizontal configuration simplifies installation under or beside equipment and allows more flexible plumbing layouts. Omnigena manufacturing and standard connectors ensure compatibility with common residential and light‑commercial systems.
Suitable for
Domestic water supply systems (pressure stabilization and reserve)
Garden and lawn irrigation with steady pressure requirements
Booster systems to reduce pump cycling and stabilize output
Small commercial or workshop water installations

EAN: 5901292912826
Type: Horizontal diaphragm pressure tank

How to use
Mount the Omnigena VAO150 on a stable horizontal surface close to the pump or system manifold, ensuring the connection fitting matches the system piping. Before commissioning, check the diaphragm condition and verify precharge pressure according to the system requirements — typically measured at the air valve with the tank drained of water. Connect piping, install necessary shut‑off and non‑return valves, then fill and purge the system to remove trapped air. Start the pump and observe pressure behavior to confirm correct operation and adjusted cut‑in/cut‑out setpoints on the pressure switch.
Usage recommendations
For reliable performance, verify the tank precharge periodically (at least annually) and adjust to the manufacturer‑recommended value for your system. Avoid exposing the tank to freezing temperatures and protect the external shell from corrosive environments. Use compatible fittings and follow local plumbing codes when integrating the Omnigena VAO150 into water supply or booster systems.
