The piCLASSIC upgraded vacuum pump series is based on COAX ® technology. With its compressed air source for energy, the product is easy to turn off and on, thus ideal for operations that only need vacuum intermittently. The unit is available with 70% more vacuum flow capacity than older designs. Its design features a low weight and a new modular design that allows the user to upgrade performance by adding cartridges (up to a total of 6). The product can be installed close to the point of vacuum and features few moving parts.
