Piab / Vacuum Pumps

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 25 to 87 psi.

Multi-stage ejector

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.
