Piab

PIAB's patent technology platform is an offshoot of the multistage technology.

COAX® ensures excellent performance at both low and high feed pressures – ideal for situations where compressed air lines deliver air at low or fluctuating pressures. Pumps based on the COAX® technology can operate within the range of 0.17 to 0.60 MPa.

Principle of the COAX® technology
Our latest technology is derived from the multi-stage ejector principle. Note that both a filter and check valves are integrated into the ejector section.
When compressed air (1) passes through the nozzles (2), air is pulled through with the stream of compressed air. "Suction" is thus created at the opening of each stage (3).

Principle of PIAB vacuum pumps
PIAB vacuum pumps are compressed air-driven vacuum pumps. The unique construction makes maximum use of the compressed air and therefore consumes less energy. Large vacuum flows and high levels of vacuum are characteristic of PIAB's vacuum pumps.
When compressed air (1) passes through the nozzles (2), air is pulled through with the stream of compressed air. "Suction" is thus created at the opening of each stage (3), resulting in low pressure, vacuum (4).
