DOVAC Overpressure 2-stage

Increased Pressure Capacity

A 2-stage side channel fan positive pressure refers to a type of side channel fan that has two stages or phases and is used to move air or gas under pressure, where the pressure on the outlet side is higher than on the inlet side.

By using two stages, a DOVAC 2-stage side channel fan can generate higher pressures than a single stage fan. This is often used in more demanding applications where greater pressure is required.

In short, the DOVAC two-stage positive pressure side channel fan is used in industries and applications where higher and greater pressures are required to move air or gas, and where reliability, efficiency and durability are important. The choice of a specific type of fan depends on the specific requirements of the process or application in which it will be used.

Packaging and processing: In the packaging industry, a two-stage side channel fan is often used for vacuum packaging of food products, such as in vacuum sealers. This fan can also come in handy in manufacturing processes that require air to move or manipulate materials, such as when handling paper, cardboard or plastic.

Medical and pharmaceutical applications: In medical and pharmaceutical environments where higher pressure is required for vacuum systems, vacuum formation in laboratory equipment, and for various process controls, this fan is often used.

Industrial Processes: In industries where higher pressure is required to move air or gases, such as in pneumatic conveying systems, air movement in process equipment, and creating vacuum in manufacturing processes, a two-stage positive pressure side channel fan can be used.

Environmental applications: For environmental applications requiring powerful airflow to extract pollutants, compact air in filtration systems, or remove air contaminants, a two-stage side channel fan can be used.

Chemical and petrochemical industry: In environments where aggressive chemicals are used or where higher pressures are required for various processes such as distillation, reaction control, and vacuum degassing, two-stage side channel fans are often used.
