COAX® technology 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.
Piab vacuum pumps are of the multi-stage ejector type – a technology patented by PIAB in 1973. These vacuum pumps were developed to provide extra vacuum flow in combination with deep maximum vacuum levels while keeping energy consumption at a minimum. Piab pumps have no moving parts that vibrate or wear out – important features that contribute heavily to outstanding operational reliability and a pleasant, noise-free working environment.
