RB-DV series of rotary three lobe PD blowers can operate at high vacuum levels thanks to a ROBUSCHI patented device that inject atmospheric air.
The new patented device allows the blower to operate at maximum vacuum without overheating.
RB-DV series blowers can reach vacuum levels of up to 93% on a dead head – 28” Hg without [...]
