These compact Roots blowers belong to the group of dry running positive displacement pumps. This means that there is no need for oil or grease in the compression chamber. Only gear box and bearings that are separated from the pumping chamber are oil lubricated. Two non contacting twin lobe Roots rotors rotate against each other in the compression room. The patented discharge system avoid pulsation problems and simultaneously minimize back flow from discharge. This results in less power requirement, higher compression ratios and a wider turn down range of the blower! Air or gas mixtures are transported in by the movement of the rotors, flow into the housing and are conveyed to the pressure side of the blower, where they are compressed against the connected pipe or system.

Variation 0102

The compact unit contains one Roots blower stage with vertical gas flow, motor, v-belt drive, flanges, filters, silencers, suction or pressure connections, pressure or vacuum relief valve, and non-return valve at pressure blowers.
