Frequently asked questions

  1. What is the difference between a membrane tank and a membrane-free tank?

    A membrane tank uses an EPDM bladder that separates water from the compressed air. A membrane-free tank is a cylindrical vessel with direct contact, for duties where that contact is acceptable.

  2. How do I size the pressure-tank volume?

    It depends on pump flow, pressure differential and starts per hour (typically 15 to 20). For booster sets: 100 L for 2–3 m³/h, 200 L for 5 m³/h, 300 L for 10 m³/h.
