## Summary description

Vertical diaphragm pressure tank Omnigena Zbiornik 100L (model VAV100) with 100 L nominal capacity. Designed to stabilize water pressure, reduce pump cycling and provide reserve water volume for domestic and light commercial water supply systems. Features a vertical orientation and internal diaphragm separating air and water for reliable pressure maintenance and corrosion protection.

## Long description

The Omnigena Zbiornik 100L vertical diaphragm pressure tank VAV100 is a 100-litre nominal capacity vessel designed for domestic and light commercial water supply systems. The tank features a vertical orientation and an internal elastomer diaphragm that separates the water chamber from the air cushion, providing stable pressure, reduced pump cycling and a modest reserve of water for intermittent demand. The durable construction and diaphragm design limit direct contact between water and the tank shell, helping to reduce corrosion and maintain consistent operation.
Advantages
The diaphragm design ensures immediate pressure response and prevents waterlogging by keeping the air and water compartments separate. Vertical layout reduces the installation footprint and is suitable for compact pump rooms. The tank supports longer pump life by minimising start-stop cycles and contributes to steady outlet pressure during short draws. Materials and internal layout are selected for routine potable water applications, delivering reliable performance in standard household and small commercial settings.
Suitable for
 Domestic water supply and pressure boosting systems
 Small commercial buildings with intermittent water demand
 Well pump installations and booster pump sets
 Systems requiring pressure stabilization and reduced pump cycling
Key specifications
 Nominal volume: 100 litres
 Orientation: Vertical
 Internal type: Diaphragm (elastomer separating air and water)
 Primary function: Pressure stabilization and water reserve
 Application: Domestic and light commercial water systems
How to use
Install the tank on a level, stable surface near the pump or pressure unit, following local plumbing codes. Connect the tank to the system using appropriate fittings and a shut-off valve for service. Ensure the diaphragm is intact and that pre-charge pressure (air cushion) matches system requirements before commissioning; if necessary, adjust the pre-charge with a pressure gauge and air valve while the tank is isolated and empty of water. After installation, run the pump and observe system pressure and cycling to confirm the tank is regulating pressure as intended. Periodic inspection of connections and the tank exterior is recommended.
Usage recommendations
Match the tank pre-charge pressure to the pump cut-in pressure (typically 2–3 bar lower than cut-out, depending on system settings) and avoid system pressures that exceed the tank's design limits. Do not expose the tank to freezing conditions or direct sunlight for prolonged periods. For best performance, include a shut-off valve and a pressure gauge at the tank connection to allow maintenance and pressure checks without draining the entire system.
