The Robuschi Rotary Lobe Blower range has been renovated, focusing on suiting its customer’s requirements. Robuschi provides premium rotary lobe blowers at varying pressures above atmospheric up to 1,000 mbar (g) and for vacuum duties up to 100 mbar (a) along with maximum air flow of 25,000 m³/h. The large number of models, sizes, options, configurations available provides solutions for most industrial applications.They can operate in pressure and vacuum, equipped as a complete package, customized according to technical requirements and providing optimal performance and maximum uptime with consistent quality and reliability in every application.
As soon as the first lobe passes the opening to the pressure side, the system pressure is adjusted. This is called isochoric compression. The rotors seal each other off to the inside, which prevents a change of pressure.
Positive displacement blowers operate using the isochoric compression principle, also known as external compression. The pressure increase is achieved by intermittently transporting a gaseous medium (e.g. atmospheric air) into a system. By forcing the medium from atmospheric conditions into a system with a given resistance (e.g. a water column, distribution network ), the relevant pressure increase is achieved. The blower will operate at a controlled output level to overcome this resistance.
Positive displacement blowers, comprise two or three conjugate lobe shaped rotors which rotate inside a pre-machined chamber. The chamber is sealed by the rotating rotors. The rotors are synchronized by means of a timing, 1:1 gear ratio, positioned at the end of the shafts. Bearings are positioned externally the compression chamber with an appropriate design lubrication system The drive shafts have labyrinth style oil seals. The lubrication systems is splash in design.
