GC - Product PVR Vacuum Design

Flyer

The GC vacuum systems are designed for those customers who need to couple vane vacuum pumps to Roots pumps with reduced overall dimensions.

This solution allows to obtain a greater capacity with a higher maximum pressure (up to 7 x 10-³ mbar) in a relatively small space.

Systems with bypass valve (GC-BP) allow the roots pump to start against atmospheric pressure

The following accessories are useful for installation and for controlling the operating parameters of the pump:

Sono disponibili i seguenti accessori utili per l’installazione e per il controllo dei parametri di funzionamento della pompa:
