Pressure tanks

Thin fluids delivered effortlessly

Low-viscosity media such as oils can be delivered to the point of application directly from pressure tanks by means of compressed air. The tanks can serve either as buffer storage within a metering system or as the main system supply. They are available in various sizes and with options, to accommodate different application requirements. With visual level indicators and electric level sensors, you will always be aware how much material is left in the tank. Alternatively, DOPAG pressure tanks are also available with mounting fixtures.
